Replication database accounts are used for database connections between databases. Replication requires the configuration of these accounts using the same username and password on all databases participating in the replication. Replication connections use fixed user database links. This means that access to the replication account on one server provides access to the other servers participating in the replication. Granting unauthorized access to the replication account provides unauthorized and privileged access to all databases participating in the replication group.

Checks: C-21420r306934_chk

From SQL*Plus: select 'The number of replication objects defined is: '|| count(*) from all_tables where table_name like 'REPCAT%'; If the count returned is 0, then Oracle Replication is not installed and this check is Not a Finding. Otherwise: From SQL*Plus: select count(*) from sys.dba_repcatlog; If the count returned is 0, then Oracle Replication is not in use and this check is Not a Finding. If any results are returned, ask the IAO or DBA if the replication account (the default is REPADMIN, but may be customized) is restricted to IAO-authorized personnel only. If it is not, this is a Finding. If there are multiple replication accounts, confirm that all are justified and documented with the IAO. If they are not, this is a Finding.

Fix: F-21419r306935_fix

Change the password for default and custom replication accounts and provide the password to IAO-authorized users only.

Oracle instance names must not contain Oracle version numbers.

Service names may be discovered by unauthenticated users. If the service name includes version numbers or other database product information, a malicious user may use that information to develop a targeted attack.

Checks: C-21421r306937_chk

From SQL*Plus: select instance_name from v$instance; select version from v$instance; If the instance name returned references the Oracle release number, this is a Finding. Numbers used that include version numbers by coincidence are not a Finding. The DBA should be able to relate the significance of the presence of a digit in the SID.

Fix: F-21420r306938_fix

Follow the instructions in Oracle MetaLink Note 15390.1 (and related documents) to change the SID for the database without re-creating the database to a value that does not identify the Oracle version.

Fixed user and public database links must be authorized for use.

Database links define connections that may be used by the local database to access remote Oracle databases. These links provide a means for a compromise to the local database to spread to remote databases in the distributed database environment. Limiting or eliminating use of database links where they are not required to support the operational system can help isolate compromises to the local or a limited number of databases.

Checks: C-21422r306940_chk

From SQL*Plus: select owner||': '||db_link from dba_db_links; select count(*) from sys.dba_repcatlog; If no records are returned from the first SQL statement, this check is Not a Finding. If the value of the count returned is 0 for the second SQL statement, none of the database links listed above, if any, is used for replication. Confirm the public and fixed user database links listed are documented in the System Security Plan, are authorized by the IAO and are used for replication or operational system requirements. If any are not, this is a Finding.

Fix: F-21421r306941_fix

Document all authorized connections from the database to remote databases in the System Security Plan. Remove all unauthorized remote database connection definitions from the database. From SQL*Plus: drop database link [link name]; OR drop public database link [link name]; Review remote database connection definitions periodically and confirm their use is still required and authorized.

A minimum of two Oracle control files must be defined and configured to be stored on separate, archived disks (physical or virtual) or archived partitions on a RAID device.

Oracle control files are used to store information critical to Oracle database integrity. Oracle uses these files to maintain time synchronization of database files as well as at system startup to verify the validity of system data and log files. Loss of access to the control files can affect database availability, integrity and recovery.

Checks: C-21423r306943_chk

From SQL*Plus: select name from v$controlfile; DoD guidance recommends: 1. A minimum of two distinct control files for each Oracle Database Instance. 2a. Each control file is to be located on separate, archived physical or logical storage devices OR 2b. Each control file is to be located on separate, archived directories within one or more RAID devices 3. The Logical Paths for each control file should differ at the highest level supported by your configuration, for example: UNIX /ora03/app/oracle/{SID}/control/control01.ctl /ora04/app/oracle/{SID}/control/control02.ctl Windows D:/oracle/{SID}/control/control01.ctl E:/oracle/{SID}/control/control02.ctl If this minimum listed above is not met, this is a Finding. Consult with the SA or DBA to determine that the mount points or partitions referenced in the file paths indicate separate physical disks or directories on RAID devices. NOTE: Distinct does not equal dedicated. You may share directory space with other Oracle database instances if present.

Fix: F-21422r306944_fix

To prevent loss of service during disk failure, multiple copies of Oracle control files should be maintained on separate disks in archived directories or on separate, archived directories within one or more RAID devices. Adding or moving a control file requires careful planning and execution. Please consult and follow the instructions for creating control files in the Oracle Database Administrator's Guide, under Steps for Creating New Control Files.

A minimum of two Oracle redo log groups/files must be defined and configured to be stored on separate, archived physical disks or archived directories on a RAID device.

An account permission to grant privileges within the database is an administrative function. Minimizing the number and privileges of administrative accounts reduces the chances of privileged account exploitation. Application user accounts should never require WITH GRANT OPTION privileges since, by definition, they require only privileges to execute procedures or view / edit data.

Checks: C-21425r306949_chk

Access to the following packages should be restricted to authorized accounts only. UTL_FILE: allows Oracle accounts to read and write files on the host operating system. UTL_SMTP: allows messages to be sent from an arbitrary user. UTL_TCP: allows arbitrary data to be sent from the database server. UTL_HTTP: allows the database server to send and receive data via HTTP. DBMS_RANDOM: allows encrypting of data without requiring safe management of encryption keys. DBMS_LOB: allows users access to files stored outside the database. DBMS_SQL: allows users to write dynamic SQL procedures. DBMS_SYS_SQL: allows users to execute SQL with DBA privileges. DBMS_JOB: allows users to submit jobs to the database job queue. DBMS_BACKUP_RESTORE: allows users to backup and restore database data. DBMS_OBFUSCATION_TOOLKIT: allows users access to encryption and decryption functions.

Fix: F-21425r306953_fix

Revoking all default installation privilege assignments from PUBLIC is not required at this time. However, execute permissions to the specified packages is required to be revoked from PUBLIC. Removal of these privileges from PUBLIC may result in invalid packages in version 10.1 and later of Oracle and an inability to execute default Oracle applications and utilities. To correct this problem, grant execute privileges on these packages directly to the SYSMAN, WKSYS, MDSYS and SYSTEM accounts as well as any other default Oracle database and custom application object owner accounts as necessary to support execution of applications/utilities installed with an Oracle Database Server. At a minimum, revoke the following: From SQL*Plus: revoke execute on UTL_FILE from PUBLIC; revoke execute on UTL_SMTP from PUBLIC; revoke execute on UTL_TCP from PUBLIC; revoke execute on UTL_HTTP from PUBLIC; revoke execute on DBMS_RANDOM from PUBLIC; revoke execute on DBMS_LOB from PUBLIC; revoke execute on DBMS_SQL from PUBLIC; revoke execute on DBMS_SYS_SQL from PUBLIC; revoke execute on DBMS_JOB from PUBLIC; revoke execute on DBMS_BACKUP_RESTORE from PUBLIC; revoke execute on DBMS_OBFUSCATION_TOOLKIT from PUBLIC;

Setting this value to TRUE allows operating system authentication over an unsecured connection. Trusting remote operating systems can allow a user to impersonate another operating system user and connect to the database without having to supply a password. If REMOTE_OS_AUTHENT is set to true, the only information a remote user needs to connect to the database is the name of any user whose account is setup to be authenticated by the operating system.

The configuration option SQL92_SECURITY specifies whether table-level SELECT privileges are required to execute an update or delete that references table column values. If this option is disabled (set to FALSE), the UPDATE privilege can be used to determine values that should require SELECT privileges. The SQL92_SECURITY setting of TRUE prevents the exploitation of user credentials with only DELETE or UPDATE privileges on a table from being able to derive column values in that table by performing a series of update/delete statements using a where clause, and rolling back the change. In the following example, with SQL92_SECURITY set to FALSE, a user with only delete privilege on the scott.emp table is able to derive that there is one employee with a salary greater than 3000. With SQL92_SECURITY set to TRUE, that user is prevented from attempting to derive a value. SQL92_SECURITY = FALSE SQL> delete from scott.emp where sal > 3000; 1 row deleted SQL> rollback; Rollback complete SQL92_SECURITY = TRUE SQL> delete from scott.emp where sal > 3000; delete from scott.emp where sal > 3000 * ERROR at line 1: ORA-01031: insufficient privileges

It is critically important to the security of your system that you protect your password file and the environment variables that identify the location of the password file. Any user with access to these could potentially compromise the security of the connection. The REMOTE_LOGIN_PASSWORDFILE setting of "NONE" disallows remote administration of the database. The REMOTE_LOGIN_PASSWORDFILE setting of "EXCLUSIVE" allows for auditing of individual DBA logins to the SYS account. If not set to "EXCLUSIVE,” remote connections to the database as "internal" or "as SYSDBA" are not logged to an individual account.

Checks: C-21430r306964_chk

From SQL*Plus: select value from v$parameter where upper(name) = 'REMOTE_LOGIN_PASSWORDFILE'; If the value returned does not equal 'EXCLUSIVE' or 'NONE', this is a Finding. On UNIX Systems: ls -ld $ORACLE_HOME/dbs/orapw${ORACLE_SID} Substitute ${ORACLE_SID} with the name of the ORACLE_SID for the database. If permissions are granted for world access, this is a finding. On Windows Systems (From Windows Explorer): Browse to the %ORACLE_HOME\database\directory. Select and right-click on the PWD%ORACLE_SID%.ora file, select Properties, select the Security tab. Substitute %ORACLE_SID% with the name of the ORACLE_SID for the database. If permissions are granted to everyone, this is a finding. If any account other than the DBMS software installation account is listed, this is a finding.

Fix: F-21429r306965_fix

Disable use of the remote_login_passwordfile where remote administration is not authorized by specifying a value of NONE.

The WITH ADMIN OPTION allows the grantee to grant a privilege to another database account. Best security practice restricts the privilege of assigning privileges to authorized personnel. Authorized personnel include DBAs, object owners, and, where designed and included in the application's functions, application administrators. Restricting privilege-granting functions to authorized accounts can help decrease mismanagement of privileges and wrongful assignments to unauthorized accounts.

System privileges can be granted to users and roles and to the user group PUBLIC. All privileges granted to PUBLIC are accessible to every user in the database. Many of these privileges convey considerable authority over the database and are granted only to those persons responsible for administering the database.

Permissions on objects may be granted to the user group PUBLIC. Because every database user is a member of the PUBLIC group, granting object permissions to PUBLIC gives all users in the database access to that object. In a secure environment, granting object permissions to PUBLIC should be restricted to those objects that all users are allowed to access.

Oracle listener authentication helps prevent unauthorized administration of the Oracle listener. Unauthorized administration of the listener could lead to DoS exploits; loss of connection audit data, unauthorized reconfiguration or other unauthorized access. This is a Category I finding because privileged access to the listener is not restricted to authorized users. Unauthorized access can result in stopping of the listener (DoS) and overwriting of listener audit logs.

Checks: C-21435r306979_chk

If a listener is not running on the local database host server, this check is Not a Finding. NOTE: This check needs to be done only once per host system and once per listener. Multiple listeners may be defined on a single host system. They must all be reviewed, but only once per database home review. For subsequent database home reviews on the same host system, mark this check as Not a Finding. Determine all Listeners running on the host. For Windows hosts, view all Windows services with TNSListener embedded in the service name - The service name format is: Oracle[ORACLE_HOME_NAME]TNSListener For UNIX hosts, the Oracle Listener process will indicate the TNSLSNR executable. At a command prompt, issue the command: ps -ef | grep tnslsnr | grep -v grep The alias for the listener follows tnslsnr in the command output. You must be logged on the host system using the account that owns the tnslsnr executable (UNIX). If the account is denied local login, have the system SA assist you in this task by 'su' to the listener account from the root account. On Windows platforms, log in using an account with administrator privileges to complete the check. From a system command prompt, execute the listener control utility: lsnrctl status [LISTENER NAME] Review the results for the value of Security. If Security = OFF is displayed, this is a Finding. If Security = ON: Local OS Authentication is displayed, this is not a Finding. If Security = ON: Password or Local OS Authentication, this is a Finding (do not set a password on Oracle versions 10.1 and higher. Instead, use Local OS Authentication). Repeat the execution of the lsnrctl utility for all active listeners.

Fix: F-21434r306980_fix

Configure the listener to use Local OS Authentication. This setting prevents remote administration of the listener, restricts management to the Oracle listener owner account (UNIX) and accounts with administrator privileges (WIN). Remote administration of the listener should not be permitted. If listener administration from a remote system is required, granting secure remote access to the Oracle DBMS server and performing local administration is preferred.

DBMS links provide a communication and data transfer path definition between two databases that may be used by malicious users to discover and obtain unauthorized access to remote systems. Database links between production and development DBMSs provide a means for developers to access production data not authorized for their access or to introduce untested or unauthorized applications to the production database. Only protected, controlled, and authorized downloads of any production data to use for development should be allowed. Only applications that have completed the configuration management process should be introduced by the application object owner account to the production system.

Separation of tablespaces by application helps to protect the application from resource contention and unauthorized access that could result from storage space reuses or host system access controls. Application data should be stored separately from system and custom user-defined objects to facilitate administration and management of its data storage. The SYSTEM tablespace should never be used for application data storage in order to prevent resource contention and performance degradation.

The LOG_ARCHIVE_DEST parameter is used to specify the directory to which Oracle archive logs are written. Where the DBMS availability and recovery to a specific point in time is critical, the protection of archive log files is critical. Archive log files may also contain unencrypted sensitive data. If written to an inadequately protected or invalidated directory, the archive log files may be accessed by unauthorized persons or processes.

Object ownership provides all database object permissions to the owned object. Access to the application object owner accounts requires special protection to prevent unauthorized access and use of the object ownership privileges. In addition to the high privileges to application objects assigned to this account, it is also an account that, by definition, is not accessed interactively except for application installation and maintenance. This reduced access to the account means that unauthorized access to the account could go undetected. To help protect the account, it should be enabled only when access is required.

Checks: C-21448r307018_chk

To obtain a list of users assigned DBA privileges, run the query: select grantee from dba_role_privs where granted_role = ’DBA’; If any records are returned, then verify the account is an authorized application object owner account or a default account installed to support an Oracle product. Verify that any objects owned by custom DBA accounts are for the personal use of that DBA. If any objects are used to support applications or any functions other than DBA functions, this is a Finding.

For UNIX Systems: Log in using the Oracle software owner account and enter the command: umask If the value returned is 022 or more restrictive, this is not a Finding. If the value returned is less restrictive than 022, this is a Finding. The first number sets the mask for user/owner file permissions. The second number sets the mask for group file permissions. The third number sets file permission mask for other users. The list below shows the available settings: 0 = read/write/execute 1 = read/write 2 = read/execute 3 = read 4 = write/execute 5 = write 6 = execute 7 = no permissions Setting the umask to 022 effectively sets files for user/owner to read/write, group to read and other to read. Directories are set for user/owner to read/write/execute, group to read/execute and other to read/execute. For Windows Systems: Review the permissions that control access to the Oracle installation software directories (e.g. \Program Files\Oracle\). DBA accounts, the DBMS process account, the DBMS software installation/maintenance account, SA accounts if access by them is required for some operational level of support such as backups, and the host system itself require access. Compare the access control employed with that documented in the System Security Plan. If access controls do not match the documented requirement, this is a Finding. If access controls appear excessive without justification, this is a Finding.

Replication accounts may be used to access databases defined for the replication architecture. An exploit of a replication on one database could lead to the compromise of any database participating in the replication that uses the same account name and credentials. If the replication account is compromised and it has DBA privileges, the database is at additional risk to unauthorized or malicious action.

Checks: C-21462r307060_chk

If a review of the System Security Plan confirms the use of replication is not required, not permitted and the database is not configured for replication, this check is Not a Finding. If any replication accounts are assigned DBA roles or roles with DBA privileges, this is a Finding.

Fix: F-21461r307061_fix

Restrict privileges assigned to replication accounts to the fewest possible privileges. Remove DBA roles from replication accounts. Create and use custom replication accounts assigned least privileges for supporting replication operations.

IP address restriction may be defined for the database listener, by use of the Oracle Connection Manager or by an external network device. Identify the method used to enforce address restriction (interview or System Security Plan review). If enforced by the database listener, then review the SQLNET.ORA file located in the ORACLE_HOME/network/admin directory (note: this assumes that a single sqlnet.ora file, in the default location, is in use; please see the supplemental file "Non-default sqlnet.ora configurations.pdf" for how to find multiple and/or differently located sqlnet.ora files) or the directory indicated by the TNS_ADMIN environment variable or registry setting. If the following entries do not exist, then restriction by IP address is not configured and is a Finding. tcp.validnode_checking=YES tcp.invited_nodes=(IP1, IP2, IP3) If enforced by an Oracle Connection Manager, then review the CMAN.ORA file for the Connection Manager (located in the TNS_ADMIN or ORACLE_HOME/network/admin directory for the connection manager). If a RULE entry allows all addresses ("/32") or does not match the address range specified in the System Security Plan, this is a Finding. (rule=(src=[IP]/27)(dst=[IP])(srv=*)(act=accept)) NOTE: an IP address with a "/" indicates acceptance by subnet mask where the number after the "/" is the left most number of bits in the address that must match for the rule to apply. If this rule is database-specific, then determine if the SERVICE_NAME parameter is set: From SQL*PLUS: select value from v$parameter where name = 'service_names'; If SERVICE_NAME is set in the initialization file for the database instance, use (srv=[service name]), else, use (srv=*) if not set or rule applies to all databases on the DBMS server. If network access restriction is performed by an external device, validate ACLs are in place to prohibit unauthorized access to the DBMS. To do this, find the IP address of the database server (destination address) and source address (authorized IPs) in the System Security Plan. Confirm only authorized IPs from the System Security Plan are allowed access to the DBMS.

Fix: F-21462r307064_fix

Configure the database listener to restrict access by IP address or set up an external device to restrict network access to the DBMS.

The cornerstone of the PKI is the private key used to encrypt or digitally sign information. If the private key is stolen, this will lead to the compromise of the authentication and non-repudiation gained through PKI because the attacker can use the private key to digitally sign documents and can pretend to be the authorized user. Both the holders of a digital certificate and the issuing authority must protect the computers, storage devices, or whatever they use to keep the private keys. All access to the private key of the DBMS must be restricted to authorized and authenticated users. If unauthorized users have access to the DBMS's private key, an attacker could gain access to the primary key and use it to impersonate the database on the network. Transport Layer Security (TLS) is the successor protocol to Secure Sockets Layer (SSL). Although the Oracle configuration parameters have names including 'SSL', such as SSL_VERSION and SSL_CIPHER_SUITES, they refer to TLS.

Checks: C-21472r307090_chk

If PKI is not enabled in Oracle Database, this is not a finding. Review DBMS configuration to determine whether appropriate access controls exist to protect the DBMS’s private key. If strong access controls do not exist to enforce authorized access to the private key, this is a finding. The database supports authentication by using digital certificates over TLS in addition to the native encryption and data integrity capabilities of these protocols. An Oracle Wallet is a container that is used to store authentication and signing credentials, including private keys, certificates, and trusted certificates needed by TLS. In an Oracle environment, every entity that communicates over TLS must have a wallet containing an X.509 version 3 certificate, private key, and list of trusted certificates, with the exception of Diffie-Hellman. If the $ORACLE_HOME/network/admin/sqlnet.ora contains the following entries, TLS is installed. (Note: This assumes that a single sqlnet.ora file, in the default location, is in use.

Application management includes the ability to control the number of users and user sessions utilizing an application. Limiting the number of allowed users, and sessions per user, is helpful in limiting risks related to Denial of Service attacks. This requirement addresses concurrent session control for a single information system account and does not address concurrent sessions by a single user via multiple system accounts. Unlimited concurrent connections to the DBMS could allow a successful Denial of Service (DoS) attack by exhausting connection resources. The organization will need to define the maximum number of concurrent sessions by account type, by account, or a combination thereof. In deciding on the appropriate number, it is important to take into account the work requirements of the various types of user. For example, 2 might be an acceptable limit for general users accessing the database via an application; but 10 might be too few for a database administrator using a database management GUI tool, where each query tab and navigation pane may count as a separate session.

Checks: C-21473r307093_chk

A comprehensive application account management process that includes automation helps to ensure accounts designated as requiring attention are consistently and promptly addressed. Examples include, but are not limited to, using automation to take action on multiple accounts designated as inactive, suspended, or terminated, or by disabling accounts located in non-centralized account stores, such as multiple servers. Enterprise environments make application user account management challenging and complex. A user management process requiring administrators to manually address account management functions adds risk of potential oversight. Automated mechanisms may be comprised of differing technologies that when placed together contain an overall automated mechanism supporting an organization's automated account management requirements. Databases can have large numbers of users in disparate locations and job functions. Automatic account management can help mitigate the risk of human error found in manually managing database access. Note that user authentication and account management should be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP This requirement applies to cases where it is necessary to have accounts directly managed by Oracle.

Checks: C-21474r307096_chk

Determine what the site-defined definition of an acceptably small level of manual account-management activity is. If the site has established the definition, documented it, and obtained ISSO-ISSM-AO approval, use that definition. If not, use the following rule of thumb as the definition: no more than 12 such accounts exist or are expected to exist; no more than 100 manual account-management actions (account creation, modification, locking, unlocking, removal and the like) are expected to occur in the course of a year. If the amount of account management activity is small, as defined in the preceding paragraph, this is not a finding. Otherwise, this is a finding.

Utilize an Oracle feature/product, an OS feature, a third-party product, or custom code to automate some or all account maintenance functionality. - - - - - Roles and Profiles are two Oracle features that should be employed in account management. (Indeed, other requirements mandate the use of Roles.) Following are some notes from Oracle on the use of Profiles. A profile is a named set of resource limits and password parameters that restrict database usage and instance resources for a user. You can assign a profile to each user, and a default profile to all others. Each user can have only one profile, and creating a new one supersedes any earlier one. Profile resource limits are enforced only when you enable resource limitation for the associated database. Enabling such limitation can occur either before starting up the database (the RESOURCE_LIMIT initialization parameter) or while it is open (using an ALTER SYSTEM statement). While password parameters reside in profiles, they are unaffected by RESOURCE_LIMIT or ALTER SYSTEM and password management is always enabled.

Strong access controls are critical to securing application data. Access control policies (e.g., identity-based policies, role-based policies, attribute-based policies) and access enforcement mechanisms (e.g., access control lists, access control matrices, cryptography) must be employed by applications, when applicable, to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, domains) in the information system. Consideration should be given to the implementation of an audited, explicit override of automated mechanisms in the event of emergencies or other serious events. If the DBMS does not follow applicable policy when approving access it may be in conflict with networks or other applications in the information system. This may result in users either gaining or being denied access inappropriately and may be in conflict with applicable policy.

Check DBMS settings to determine whether users are restricted from accessing objects and data they are not authorized to access. If appropriate access controls are not implemented to restrict access to authorized users and to restrict the access of those users to objects and data they are authorized to see, this is a finding. The easiest way to isolate access is by using the Oracle Database Vault. To check to see if the Oracle Database Vault is installed issue the following query: SQL> SELECT * FROM V$OPTION WHERE PARAMETER = 'Oracle Database Vault'; If Oracle Database Vault is installed, review its settings for appropriateness and completeness of the access it permits and denies to each type of user. If appropriate and complete, this is not a finding.

Audit records can be generated from various components within the information system. (e.g., network interface, hard disk, modem, etc.). From an application perspective, certain specific application functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records (i.e., auditable events, timestamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked). Organizations define which application components shall provide auditable events. The DBMS must provide auditing for the list of events defined by the organization or risk negatively impacting forensic investigations into malicious behavior in the information system. Audit records can be generated from various components within the information system, such as network interfaces, hard disks, modems, etc. From an application perspective, certain specific application functionalities may be audited, as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records (i.e., auditable events, timestamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked). Organizations may define the organizational personnel accountable for determining which application components shall provide auditable events. Auditing provides accountability for changes made to the DBMS configuration or its objects and data. It provides a means to discover suspicious activity and unauthorized changes. Without auditing, a compromise may go undetected and without a means to determine accountability. The Department of Defense has established the following as the minimum set of auditable events. Most can be audited via Oracle settings; some may require OS settings. - Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g. classification levels). - Successful and unsuccessful logon attempts, privileged activities or other system level access - Starting and ending time for user access to the system, concurrent logons from different workstations. - Successful and unsuccessful accesses to objects. - All program initiations. - All direct access to the information system. - All account creations, modifications, disabling, and terminations. - All kernel module loads, unloads, and restarts.

Checks: C-21476r307102_chk

Verify, using vendor and system documentation if necessary, that the DBMS is configured to use Oracle's auditing features, or that a third-party product or custom code is deployed and configured to satisfy this requirement. If a third-party product or custom code is used, compare its current configuration with the audit requirements. If any of the requirements is not covered by the configuration, this is a finding. The remainder of this Check is applicable specifically where Oracle auditing is in use. To see if Oracle is configured to capture audit data, enter the following SQLPlus command: SHOW PARAMETER AUDIT_TRAIL or the following SQL query: SELECT * FROM SYS.V$PARAMETER WHERE NAME = 'audit_trail'; If Oracle returns the value 'NONE', this is a finding. To confirm that Oracle audit is capturing information on the required events, review the contents of the SYS.AUD$ table or the audit file, whichever is in use. If auditable events are not listed, this is a finding.

Fix: F-21475r307103_fix

Configure the DBMS's auditing to audit organization-defined auditable events. If preferred, use a third-party tool. The tool must provide the minimum capability to audit the required events. If using a third-party product, proceed in accordance with the product documentation. If using Oracle's capabilities, proceed as follows.

The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records (i.e., auditable events, timestamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked). If the list of auditable events is not configurable, events that should be caught by auditing may be missed. This may allow malicious activity to be overlooked.

Checks: C-21477r307105_chk

Check DBMS settings and documentation to determine whether designated personnel are able to select which auditable events are being audited. If designated personnel are not able to configure auditable events, this is a finding.

Fix: F-21476r307106_fix

Configure the DBMS's settings to allow designated personnel to select which auditable events are audited. Note the following: In Oracle, any user can configure auditing for the objects in his or her own schema by using the AUDIT statement. To undo the audit configuration for an object, the user can use the NOAUDIT statement. No additional privileges are needed to perform this task. To audit objects in another schema, the user must have the AUDIT ANY system privilege. To audit system privileges, the user must have the AUDIT SYSTEM privilege. For more information on the configuration of auditing, please refer to "Auditing Database Activity" in the Oracle Database 2 Day + Security Guide: http://docs.oracle.com/cd/E11882_01/server.112/e10575/tdpsg_auditing.htm and "Verifying Security Access with Auditing" in the Oracle Database Security Guide: http://docs.oracle.com/cd/E11882_01/network.112/e36292/auditing.htm#DBSEG006 and "27 DBMS_AUDIT_MGMT" in the Oracle Database PL/SQL Packages and Types Reference: http://docs.oracle.com/cd/E11882_01/appdev.112/e40758/d_audit_mgmt.htm

Audit records can be generated from various components within the information system, such as network interfaces, hard disks, modems, etc. From an application perspective, certain specific application functionalities may be audited, as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records (i.e., auditable events, timestamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked). Organizations may define the organizational personnel accountable for determining which application components shall provide auditable events. Auditing provides accountability for changes made to the DBMS configuration or its objects and data. It provides a means to discover suspicious activity and unauthorized changes. Without auditing, a compromise may go undetected and without a means to determine accountability. The Department of Defense has established the following as the minimum set of auditable events. Most can be audited via Oracle settings; some may require OS settings. - Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g. classification levels). - Successful and unsuccessful logon attempts, privileged activities or other system level access - Starting and ending time for user access to the system, concurrent logons from different workstations. - Successful and unsuccessful accesses to objects. - All program initiations. - All direct access to the information system. - All account creations, modifications, disabling, and terminations. - All kernel module loads, unloads, and restarts.

Checks: C-21478r307108_chk

Check DBMS and OS settings to determine if auditing is being performed on the events on the DoD-selected list of auditable events. If auditing is not being performed for any of the events on the DoD-selected list of auditable events, this is a finding.

If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In addition, access to audit records provides information an attacker could potentially use to his or her advantage. To ensure the veracity of audit data, the information system and/or the application must protect audit information from any and all unauthorized access. This includes read, write, copy, etc. This requirement can be achieved through multiple methods which will depend upon system architecture and design. Some commonly employed methods include ensuring log files enjoy the proper file system permissions utilizing file system protections and limiting log data location. Additionally, applications with user interfaces to audit records must not allow for the unfettered manipulation of or access to those records via the application. If the application provides access to the audit data, the application becomes accountable for ensuring that audit information is protected from unauthorized access. Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity.

Add controls and modify permissions to protect database audit log data from unauthorized modification, whether stored in the database itself or at the OS level. - - - - - Revoke access to the AUD$ table to anyone who you do not want to have access to the AUD$ table. In the check we looked for all users who had access to the AUD$ table. To fix this, use the REVOKE command to revoke access to users who should not have access to the audit data. REVOKE statement Use the REVOKE statement to remove permissions from a specific user or from all users to perform actions on database objects. The following types of permissions can be revoked: Delete data from a specific table. Insert data into a specific table. Create a foreign key reference to the named table or to a subset of columns from a table. Select data from a table, view, or a subset of columns in a table. Create a trigger on a table. Update data in a table or in a subset of columns in a table. Run a specified routine (function or procedure). If a user named FRED had access to the AUD$ table and you want to revoke that access, use the following command. The syntax that you use for the REVOKE statement for tables is as follows: REVOKE privilege-type ON [ TABLE ] { table-Name | view-Name } FROM grantees SQL>REVOKE SELECT ON TABLE AUD$ FROM FRED; Revoking a privilege without specifying a column list revokes the privilege for all of the columns in the table. Syntax for routines table-privileges include DELETE | INSERT | REFERENCES [column list] | SELECT [column list] | TRIGGER | UPDATE [column list] column list ( column-identifier {, column-identifier}* ) Use the ALL PRIVILEGES privilege type to revoke all of the permissions from the user for the specified table. You can also revoke one or more table privileges by specifying a privilege-list. Use the DELETE privilege type to revoke permission to delete rows from the specified table. Use the INSERT privilege type to revoke permission to insert rows into the specified table. Use the REFERENCES privilege type to revoke permission to create a foreign key reference to the specified table. If a column list is specified with the REFERENCES privilege, the permission is revoked on only the foreign key reference to the specified columns. Use the SELECT privilege type to revoke permission to perform SELECT statements on a table or view. If a column list is specified with the SELECT privilege, the permission is revoked on only those columns. If no column list is specified, then the privilege is valid on all of the columns in the table. Use the TRIGGER privilege type to revoke permission to create a trigger on the specified table. Use the UPDATE privilege type to revoke permission to use the UPDATE statement on the specified table. If a column list is specified, the permission is revoked only on the specified columns. grantees { authorization ID | PUBLIC } [,{ authorization ID | PUBLIC } ] * You can revoke the privileges from specific users or from all users. Use the keyword PUBLIC to specify all users. The privileges revoked from PUBLIC and from individual users are independent privileges. For example, a SELECT privilege on table t is granted to both PUBLIC and to the authorization ID harry. The SELECT privilege is later revoked from the authorization ID 'Harry', but the authorization ID 'Harry' can access the table through the PUBLIC privilege. Restriction: You cannot revoke the privileges of the owner of an object. routine-designator { qualified-name [ signature ] } Cascading object dependencies For views, triggers, and constraints, if the privilege on which the object depends on is revoked, the object is automatically dropped. Derby does not try to determine if you have other privileges that can replace the privileges that are being revoked. For more information, see "SQL standard authorization" in the Java DB Developer's Guide. Limitations The following limitations apply to the REVOKE statement: Table-level privileges All of the table-level privilege types for a specified grantee and table ID are stored in one row in the SYSTABLEPERMS system table. For example, when user2 is granted the SELECT and DELETE privileges on table user1.t1, a row is added to the SYSTABLEPERMS table. The GRANTEE field contains user2 and the TABLEID contains user1.t1. The SELECTPRIV and DELETEPRIV fields are set to Y. The remaining privilege type fields are set to N. When a grantee creates an object that relies on one of the privilege types, the Derby engine tracks the dependency of the object on the specific row in the SYSTABLEPERMS table. For example, user2 creates the view v1 by using the statement SELECT * FROM user1.t1; the dependency manager tracks the dependency of view v1 on the row in SYSTABLEPERMS for GRANTEE(user2), TABLEID(user1.t1). The dependency manager knows only that the view is dependent on a privilege type in that specific row but does not track exactly which privilege type the view is dependent on. When a REVOKE statement for a table-level privilege is issued for a grantee and table ID, all of the objects that are dependent on the grantee and table ID are dropped. For example, if user1 revokes the DELETE privilege on table t1 from user2, the row in SYSTABLEPERMS for GRANTEE(user2), TABLEID(user1.t1) is modified by the REVOKE statement. The dependency manager sends a revoke invalidation message to the view user2.v1, and the view is dropped, even though the view is not dependent on the DELETE privilege for GRANTEE(user2), TABLEID(user1.t1). Column-level privileges Only one type of privilege for a specified grantee and table ID are stored in one row in the SYSCOLPERMS system table. For example, when user2 is granted the SELECT privilege on table user1.t1 for columns c12 and c13, a row is added to the SYSCOLPERMS. The GRANTEE field contains user2, the TABLEID contains user1.t1, the TYPE field contains S, and the COLUMNS field contains c12, c13. When a grantee creates an object that relies on the privilege type and the subset of columns in a table ID, the Derby engine tracks the dependency of the object on the specific row in the SYSCOLPERMS table. For example, user2 creates the view v1 by using the statement SELECT c11 FROM user1.t1; the dependency manager tracks the dependency of view v1 on the row in SYSCOLPERMS for GRANTEE(user2), TABLEID(user1.t1), TYPE(S). The dependency manager knows that the view is dependent on the SELECT privilege type but does not track exactly which columns the view is dependent on. When a REVOKE statement for a column-level privilege is issued for a grantee, table ID, and type, all of the objects that are dependent on the grantee, table ID, and type are dropped. For example, if user1 revokes the SELECT privilege on column c12 on table user1.t1 from user2, the row in SYSCOLPERMS for GRANTEE(user2), TABLEID(user1.t1), TYPE(S) is modified by the REVOKE statement. The dependency manager sends a revoke invalidation message to the view user2.v1, and the view is dropped, even though the view is not dependent on the column c12 for GRANTEE(user2), TABLEID(user1.t1), TYPE(S). Revoke examples To revoke the SELECT privilege on table t from the authorization IDs 'Maria' and 'Harry', use the following syntax: SQL>REVOKE SELECT ON TABLE t FROM maria,harry To revoke the UPDATE and TRIGGER privileges on table t from the authorization IDs 'Anita' and 'Zhi', use the following syntax: SQL>REVOKE UPDATE, TRIGGER ON TABLE t FROM anita,zhi To revoke the SELECT privilege on table s.v from all users, use the following syntax: SQL>REVOKE SELECT ON TABLE s.v FROM PUBLIC To revoke the UPDATE privilege on columns c1 and c2 of table s.v from all users, use the following syntax: SQL>REVOKE UPDATE (c1,c2) ON TABLE s.v FROM PUBLIC To revoke the EXECUTE privilege on procedure p from the authorization ID 'George', use the following syntax: SQL>REVOKE EXECUTE ON PROCEDURE p FROM george RESTRICT

Within the database, object ownership implies full privileges to the owned object including the privilege to assign access to the owned objects to other subjects. Unmanaged or uncontrolled ownership of objects can lead to unauthorized object grants and alterations, and unauthorized modifications to data. If critical tables or other objects rely on unauthorized owner accounts, these objects can be lost when an account is removed. It may be the case that there are accounts that are authorized to own synonyms, but no other objects. If this is so, it should be documented.

If Oracle is hosted on a server that does not support production systems, and is designated for the deployment of samples and demonstrations, this is not applicable (NA). Review documentation and websites from Oracle and any other relevant vendors for vendor-provided demonstration or sample databases, database applications, schemas, objects, and files. Review the Oracle DBMS to determine if any of the demonstration and sample databases, schemas, database applications, or files are installed in the database or are included with the DBMS application. If any are present in the database or are included with the DBMS application, this is a finding.

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions). It is detrimental for applications to provide, or install by default, functionality exceeding requirements or mission objectives. Examples include, but are not limited to, installing advertising software, demonstrations, or browser plug-ins not related to requirements or providing a wide array of functionality not required for the mission. Applications must adhere to the principles of least functionality by providing only essential capabilities. Demonstration and sample database objects and applications present publicly known attack points for malicious users. These demonstration and sample objects are meant to provide simple examples of coding specific functions and are not developed to prevent vulnerabilities from being introduced to the DBMS and host system.

The Oracle external procedure capability provides use of the Oracle process account outside the operation of the DBMS process. You can use it to submit and execute applications stored externally from the database under operating system controls. The external procedure process is the subject of frequent and successful attacks as it allows unauthenticated use of the Oracle process account on the operating system. As of Oracle version 11.1, the external procedure agent may be run directly from the database and not require use of the Oracle listener. This reduces the risk of unauthorized access to the procedure from outside of the database process.

Checks: C-21497r307165_chk

Review the System Security Plan to determine if the use of the external procedure agent is authorized. Review the ORACLE_HOME/bin directory or search the ORACLE_BASE path for the executable extproc (UNIX) or extproc.exe (Windows). If external procedure agent is not authorized for use in the System Security Plan and the executable file does not exist or is restricted, this is not a finding. If external procedure agent is not authorized for use in the System Security Plan and the executable file exists and is not restricted, this is a finding. If use of the external procedure agent is authorized, ensure extproc is restricted to execution of authorized applications. External jobs are run using the account nobody by default. Review the contents of the file ORACLE_HOME/rdbms/admin/externaljob.ora for the lines run_user= and run_group=. If the user assigned to these parameters is not "nobody", this is a finding. For versions 11.1 and later, the external procedure agent (extproc executable) is available directly from the database and does not require definition in the listener.ora file for use. Review the contents of the file ORACLE_HOME/hs/admin/extproc.ora. If external processes are allowed, but the file does not exist, this is a finding. If the following entry does not appear in the file, this is a finding: EXTPROC_DLLS=ONLY:[dll full file name1]:[dll full file name2]:.. [dll full file name] represents a full path and file name. This list of file names is separated by ":". If "ONLY" is specified, then the list is restricted to allow execution of only the DLLs specified in the list and is not a finding. If "ANY" is specified, then there are no restrictions for execution except what is controlled by operating system permissions and is a finding. If no specification is made, any files located in the %ORACLE_HOME%\bin directory on Windows systems or $ORACLE_HOME/lib directory on UNIX systems can be executed (the default) and is a finding. Ensure that EXTPROC is not accessible from the listener. Review the listener.ora file. If any entries reference "extproc", this is a finding. Determine if the external procedure agent is in use per Oracle 10.x conventions. Review the listener.ora file. If any entries reference "extproc", then the agent is in use. If external procedure agent is not authorized for use in the System Security Plan and references to "extproc" exist, this is a finding. Sample listener.ora entries with extproc included: LISTENER = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) ) EXTLSNR = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC)) ) SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = ORCL) (ORACLE_HOME = /home/oracle/app/oracle/product/11.1.0/db_1) (SID_NAME = ORCL) ) ) SID_LIST_EXTLSNR = (SID_LIST = (SID_DESC = (PROGRAM = extproc) (SID_NAME = PLSExtProc) (ORACLE_HOME = /home/oracle/app/oracle/product/11.1.0/db_1) (ENVS="EXTPROC_DLLS=ONLY:/home/app1/app1lib.so:/home/app2/app2lib.so, LD_LIBRARY_PATH=/private/app2/lib:/private/app1, MYPATH=/usr/fso:/usr/local/packages") ) ) Sample tnsnames.ora entries with extproc included: ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = ORCL) ) ) EXTPROC_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = extproc)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = PLSExtProc) ) ) If EXTPROC is in use, confirm that a listener is dedicated to serving the external procedure agent (as shown above). View the protocols configured for the listener. For the listener to be dedicated, the only entries will be to specify extproc. If there is not a dedicated listener in use for the external procedure agent, this is a finding. If the PROTOCOL= specified is other than IPC, this is a finding. Verify and ensure extproc is restricted executing authorized external applications only and extproc is restricted to execution of authorized applications. Review the listener.ora file. If the following entry does not exist, this is a finding: EXTPROC_DLLS=ONLY:[dll full file name1]:[dll full file name2]:... [dll full file name] represents a full path and file name. This list of file names is separated by ":". If "ONLY" is specified, then the list is restricted to allow execution of only the DLLs specified in the list and is not a finding. If "ANY" is specified, then there are no restrictions for execution except what is controlled by operating system permissions and is a finding. If no specification is made, any files located in the %ORACLE_HOME%\bin directory on Windows systems or $ORACLE_HOME/lib directory on UNIX systems can be executed (the default) and is a finding. View the listener.ora file (usually in ORACLE_HOME/network/admin or directory specified by the TNS_ADMIN environment variable). If multiple listener processes are running, then the listener.ora file for each must be viewed. For each process, determine the directory specified in the ORACLE_HOME or TNS_ADMIN environment variable defined for the process account to locate the listener.ora file.

If the use of external procedure agent is required, then authorize and document the requirement in the System Security Plan. If the external procedure agent must be accessible to the Oracle listener, then specify this and authorize it in the System Security Plan. If use of the Oracle External Procedure agent is not required: - Stop the Oracle Listener process - Remove all references to extproc in the listener.ora and tnsnames.ora files - Alter the permissions on the executable files: UNIX - Remove read/write/execute permissions from owner, group and world Windows - Remove Groups/Users from the executable (except groups SYSTEM and ADMINISTRATORS) and allow READ [only] for SYSTEM and ADMINISTRATORS groups If required: - Restrict extproc execution to only authorized applications. - Specify EXTPROC_DLLS=ONLY: [list of authorized DLLS] in the extproc.ora and the listener.ora files - Create a separate, dedicated listener for use by the external procedure agent Please see the Oracle Net Services Administrators Guides, External Procedures section for detailed configuration information.

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions). Additionally, it is sometimes convenient to provide multiple services from a single component of an information system (e.g., email and web services), but doing so increases risk by constraining the ability to restrict the use of functions, ports, protocols, and/or services. To support the requirements and principles of least functionality, the application must support the organizational requirements providing only essential capabilities and limiting the use of ports, protocols, and/or services to only those required, authorized, and approved to conduct official business or to address authorized quality of life issues. Database Management Systems using ports, protocols, and services deemed unsafe are open to attack through those ports, protocols, and services. This can allow unauthorized access to the database and through the database to other components of the information system.

Applications must enforce password encryption when storing passwords. Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read and easily compromised. Database passwords stored in clear text are vulnerable to unauthorized disclosure. Database passwords must always be encoded or encrypted when stored internally or externally to the DBMS.

Checks: C-21499r307171_chk

(Oracle stores and displays its passwords in encrypted form. Nevertheless, this should be verified by reviewing the relevant system views, along with the other items to be checked here.) Ask the DBA to review the list of DBMS database objects, database configuration files, associated scripts, and applications defined within and external to the DBMS that access the database. The list should also include files, tables or settings used to configure the operational environment for the DBMS and for interactive DBMS user accounts. Ask the DBA and/or IAO to determine if any DBMS database objects, database configuration files, associated scripts, and applications defined within or external to the DBMS that access the database, and DBMS/user environment files/settings/tables, contain database passwords. If any do, confirm that DBMS passwords stored internally or externally to the DBMS are encoded or encrypted. If any passwords are stored in clear text, this is a finding. Ask the DBA/SA/Application Support staff if they have created an external password store for applications, batch jobs, and scripts to use. Verify that all passwords stored there are encrypted. If a password store is used and any password is not encrypted, this is a finding. The following are notes on implementing a Secure External Password Store using Oracle Wallet: You can store password credentials for connecting to databases by using a client-side Oracle wallet. An Oracle wallet is a secure software container that stores authentication and signing credentials. This wallet usage can simplify large-scale deployments that rely on password credentials for connecting to databases. When this feature is configured, application code, batch jobs, and scripts no longer need embedded user names and passwords. This reduces risk because the passwords are no longer exposed, and password management policies are more easily enforced without changing application code whenever user names or passwords change. The external password store of the wallet is separate from the area where public key infrastructure (PKI) credentials are stored. Consequently, you cannot use Oracle Wallet Manager to manage credentials in the external password store of the wallet. Instead, use the command-line utility mkstore to manage these credentials. How Does the External Password Store Work? Typically, users (and applications, batch jobs, and scripts) connect to databases by using a standard CONNECT statement that specifies a database connection string. This string can include a user name and password, and an Oracle Net service name identifying the database on an Oracle Database network. If the password is omitted, the connection prompts the user for the password. For example, the service name could be the URL that identifies that database, or a TNS alias you entered in the tnsnames.ora file in the database. Another possibility is a host:port:sid string. The following examples are standard CONNECT statements that could be used for a client that is not configured to use the external password store: CONNECT salesapp@sales_db.us.example.com Enter password: password CONNECT salesapp@orasales Enter password: password CONNECT salesapp@ourhost37:1527:DB17 Enter password: password In these examples, salesapp is the user name, with the unique connection string for the database shown as specified in three different ways. You could use its URL sales_db.us.example.com, or its TNS alias, orasales, from the tnsnames.ora file, or its host:port:sid string. However, when clients are configured to use the secure external password store, applications can connect to a database with the following CONNECT statement syntax, without specifying database logon credentials: CONNECT /@db_connect_string CONNECT /@db_connect_string AS SYSDBA CONNECT /@db_connect_string AS SYSOPER In this specification, db_connect_string is a valid connection string to access the intended database, such as the service name, URL, or alias as shown in the earlier examples. Each user account must have its own unique connection string; you cannot create one connection string for multiple users. In this case, the database credentials, user name and password, are securely stored in an Oracle wallet created for this purpose. The autologin feature of this wallet is turned on, so the system does not need a password to open the wallet. From the wallet, it gets the credentials to access the database for the user they represent.

Fix: F-21498r307172_fix

Develop, document, and maintain a list of DBMS database objects, database configuration files, associated scripts, and applications defined within or external to the DBMS that access the database, and DBMS/user environment files/settings in the System Security Plan. Record whether they do or do not contain DBMS passwords. If passwords are present, ensure they are encoded or encrypted and protected by host system security. The following are notes on implementing a Secure External Password Store using Oracle Wallet: Oracle provides the capability to provide for a secure external password facility. Use the Oracle mkstore to create a secure storage area for passwords for applications, batch jobs, and scripts to use, or deploy a site-authorized facility to perform this function. Check to see what has been stored in the Oracle External Password Store. To view all contents of a client wallet external password store, check specific credentials by viewing them. Listing the external password store contents provides information you can use to decide whether to add or delete credentials from the store. To list the contents of the external password store, enter the following command at the command line: $ mkstore -wrl wallet_location -listCredential For example: $ mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -listCredential The wallet_location specifies the path to the directory where the wallet, whose external password store contents you want to view, is located. This command lists all of the credential database service names (aliases) and the corresponding user name (schema) for that database. Passwords are not listed. Configuring Clients to use the External Password Store: If your client is already configured to use external authentication, such as Windows native authentication or Transport Layer Security (TLS), then Oracle Database uses that authentication method. The same credentials used for this type of authentication are typically also used to log in to the database. For clients not using such authentication methods or wanting to override them for database authentication, you can set the SQLNET.WALLET_OVERRIDE parameter in sqlnet.ora to TRUE. The default value for SQLNET.WALLET_OVERRIDE is FALSE, allowing standard use of authentication credentials as before. If you want a client to use the secure external password store feature, then perform the following configuration task: 1. Create a wallet on the client by using the following syntax at the command line: mkstore -wrl wallet_location -create For example: mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -create Enter password: password The wallet_location is the path to the directory where you want to create and store the wallet. This command creates an Oracle wallet with the autologin feature enabled at the location you specify. The autologin feature enables the client to access the wallet contents without supplying a password. The mkstore utility -create option uses password complexity verification. 2. Create database connection credentials in the wallet by using the following syntax at the command line: mkstore -wrl wallet_location -createCredential db_connect_string username Enter password: password For example: mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -createCredential oracle system Enter password: password In this specification the wallet_location is the path to the directory where you created the wallet. The db_connect_string used in the CONNECT /@db_connect_string statement must be identical to the db_connect_string specified in the -createCredential command. The db_connect_string is the TNS alias you use to specify the database in the tnsnames.ora file or any service name you use to identify the database on an Oracle network. By default, tnsnames.ora is located in the $ORACLE_HOME/network/admin directory on UNIX systems and in ORACLE_HOME\network\admin on Windows. The username is the database logon credential. When prompted, enter the password for this user. 3. In the client sqlnet.ora file, enter the WALLET_LOCATION parameter and set it to the directory location of the wallet you created in Step 1. For example, if you created the wallet in $ORACLE_HOME/network/admin and your Oracle home is set to /private/ora11, then you need to enter the following into your client sqlnet.ora file: WALLET_LOCATION = (SOURCE = (METHOD = FILE) (METHOD_DATA = (DIRECTORY = /private/ora11/network/admin) ) ) 4. In the client sqlnet.ora file, enter the SQLNET.WALLET_OVERRIDE parameter and set it to TRUE as follows: SQLNET.WALLET_OVERRIDE = TRUE This setting causes all CONNECT /@db_connect_string statements to use the information in the wallet at the specified location to authenticate to databases. When external authentication is in use, an authenticated user with such a wallet can use the CONNECT /@db_connect_string syntax to access the previously specified databases without providing a user name and password. However, if a user fails that external authentication, then these connect statements also fail. Below is a sample sqlnet.ora file with the WALLET_LOCATION and the SQLNET.WALLET_OVERRIDE parameters set as described in Steps 3 and 4. WALLET_LOCATION = (SOURCE = (METHOD = FILE) (METHOD_DATA = (DIRECTORY = /private/ora11/network/admin) ) ) SQLNET.WALLET_OVERRIDE = TRUE SSL_CLIENT_AUTHENTICATION = FALSE SSL_VERSION = 1.2 (Note: This assumes that a single sqlnet.ora file, in the default location, is in use. Please see the supplemental file "Non-default sqlnet.ora configurations.pdf" for how to find multiple and/or differently located sqlnet.ora files.)

A trust anchor is an authoritative entity represented via a public key and associated data. It is used in the context of public key infrastructures, X.509 digital certificates, and DNSSEC. When there is a chain of trust, usually the top entity to be trusted becomes the trust anchor; it can be for example a Certification Authority (CA). A certification path starts with the Subject certificate and proceeds through a number of intermediate certificates up to a trusted root certificate, typically issued by a trusted CA. Path validation is necessary for a relying party to make an informed trust decision when presented with any certificate not already explicitly trusted. Status information for certification paths includes certificate revocation lists or online certificate status protocol responses. Database Management Systems that do not validate certificates to a trust anchor are in danger of accepting certificates that are invalid and/or counterfeit. This could allow unauthorized access to the database.

The cornerstone of the PKI is the private key used to encrypt or digitally sign information. The key by itself is a cryptographic value that does not contain specific user information. When including the DBMS in the Private Key Infrastructure, the authenticated user must map directly to a user account in the DBMS.

Just as individual users must be authenticated, and just as they must use PKI-based authentication, so must any processes that connect to the DBMS. The DoD standard for authentication of a process or device communicating with another process or device is the presentation of a valid, current, DoD-issued Public Key Infrastructure (PKI) certificate that has previously been verified as Trusted by an administrator of the other process or device. This applies both to processes that run on the same server as the DBMS and to processes running on other computers. The Oracle-supplied super-user account, SYS, is an exception. It cannot currently use certificate-based authentication. For this reason among others, use of SYS should be restricted to where it is truly needed.

Encryption is only as good as the encryption modules utilized. Unapproved cryptographic module algorithms cannot be verified and cannot be relied upon to provide confidentiality or integrity, and DoD data may be compromised due to weak algorithms. Applications utilizing encryption are required to use approved encryption modules that meet the requirements of applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. FIPS 140-2 is the current standard for validating cryptographic modules, and NSA Type-X (where X=1, 2, 3, 4) products are NSA-certified hardware-based encryption modules. Authentication modules with weak encryption could allow an attacker to gain access to data stored in the database and to the administration settings of the DBMS.

This requirement focuses on communications protection at the application session, versus network packet, level. Session IDs are tokens generated by web applications to uniquely identify an application user's session. Applications will make application decisions and execute business logic based on the session ID. Unique session identifiers or IDs are the opposite of sequentially generated session IDs, which can be easily guessed by an attacker. Unique session IDs help to reduce predictability of said identifiers. Unique session IDs address man-in-the-middle attacks, including session hijacking or insertion of false information into a session. If the attackers are unable to identify or guess the session information related to pending application traffic, they will have more difficulty in hijacking the session or otherwise manipulating valid sessions. When a user logs out, or when any other session termination event occurs, the application must terminate the user session to minimize the potential for an attacker to hijack that particular user session. Database sessions must be terminated when no longer in use in order to prevent session hijacking.

Checks: C-21504r307186_chk

Review DBMS settings and vendor documentation to verify user sessions are terminated upon user logout. If they are not, this is a finding. Review system documentation and organization policy to identify other events that should result in session terminations. If other session termination events are defined, review DBMS settings to verify occurrences of these events would cause session termination. If occurrences of defined session-terminating events do not cause session terminations, this is a finding. When a user logs out of an Oracle session gracefully or has the session terminated for an idle timeout or any other reason, the session is terminated, and the resources are returned to the system. Check with the DBA to see what mechanism is used to disconnect the session and what events the site uses to determine if a connection needs to be terminated. To test for timeout, open a connection and leave it idle for a period greater than the defined idle timeout setting enforced by the system. Then try to use the connection. If the connection is no longer active, then the mechanism deployed to terminate the connection is active and working.

Fix: F-21503r307187_fix

Configure DBMS settings to terminate sessions upon user logout. Configure DBMS settings to terminate sessions upon the occurrence of any organization or policy-defined session termination event. - - - - - To configure specific session termination processes we need to define the organization or policy-defined session termination event. Below are some examples. Oracle has several ways to disconnect idle sessions, both from within SQL*Plus via resources profiles (connect_time, idle_time) and with the SQL*net expire time parameter. You can use profiles to set the connect time and idle time with "alter profile" statements: alter profile senior_claim_analyst limit connect_time 180000 sessions_per_user 2 ldle_time 1800; Profiles comprise a named set of resource limits. By default, when you create users, they are given the default profile, which provides unlimited use of all resources. The syntax to create a profile follows: CREATE PROFILE LIMIT resource_parameters|password_parameters; Resource_parameters: [SESSIONS_PER_USER n|UNLIMITED|DEFAULT] [CPU_PER_SESSION n|UNLIMITED|DEFAULT] [CPU_PER_CALL n|UNLIMITED|DEFAULT] [CONNECT_TIME n|UNLIMITED|DEFAULT] [IDLE_TIME n|UNLIMITED|DEFAULT] By setting resource limits, you can prevent users from performing operations that will tie up the system and prevent other users from performing operations. You can use resource limits for security, to ensure that users log off the system, so as not to leave the session connected for long periods of time. The system resource limits can be enforced at the session-level, the call level, or both. The session-level is calculated from the time the user logs in to the database until the user exits. The call level applies to each SQL command issued. Session-level limits are enforced for each connection. When a session-level limit is exceeded, only the last SQL command issued is rolled back; no further work can be performed until a commit, rollback, or exit is performed. Using SQLNET.EXPIRE_TIME The sqlnet.expire_time parameter is used to set a time interval, in minutes, to determine how often a probe should be sent verifying that client/server connections are active. If you need to ensure that connections are not left open indefinitely (or up to the time set by operating system-specific parameters), you should set a value that is greater than 0. This protects the system from connections left open due to an abnormal client termination. When the probe detects a terminated connection or a connection no longer in use, it signals an error, causing the server process to exit. This setting is intended for use on the database server side of the connection, which usually handles multiple connections at any one time. Limitations on using this terminated (dead) connection detection feature are: sqlnet.expire_time cannot be used on bequeathed connections. The SQL*Net expire_time probe packet will generate additional network traffic that may downgrade the network's performance, depending on the number of connections. Depending on the operating system that is in use, additional server processing may need to be performed to distinguish the connection probe from other events that occur. This overhead for detection of probe events can result in downgraded network performance. Turning-on expire_time To set up these advanced features, simply edit your sqlnet.ora file. If you are a beginner, follow this procedure: Start the Oracle Network Manager GUI. In the GUI navigator pane, expand the icons Local > Profile. From the list on the right hand pane, select General. Click on the Advanced tab. Next, enter the values for the fields or options you want to set. When you are finished, choose File > Save Network Configuration to write your changes to the sqlnet.ora file. (Note: This assumes that a single sqlnet.ora file, in the default location, is in use. Please see the supplemental file "Non-default sqlnet.ora configurations.pdf" for how to find multiple and/or differently located sqlnet.ora files.) The sqlnet.ora inbound_connect_timeout parameter The sqlnet.ora inbound_connect_timeout parameter is used to limit the time, set in seconds, for a client to connect with the database server and provide the required authentication information. Also see sqlnet.inbound_connect_timeout tips. To limit consumption of Oracle resources by unauthorized users and enable an audit trail, you should set time-limit values for the sqlnet.inbound_connect_timeout parameter in wall-clock seconds. (This parameter does not have default values.) Failure resulting from sqlnet.inbound_connect_timeout will throw an ORA-03136 inbound connection timed out error.

Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive, tape drive) within an organizational information system. Applications and application users generate information throughout the course of their application use. User-generated data and application specific configuration data both need to be protected. Configurations and/or rule sets for firewalls, gateways, intrusion detection/prevention systems, and filtering routers and authenticator content are examples of system information likely requiring protection. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate.

Security functions are defined as "the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based". Developers and implementers can increase the assurance in security functions by employing well-defined security policy models, structured, disciplined, and rigorous hardware and software development techniques, and sound system/security engineering principles. Database Management Systems typically separate security functionality from non-security functionality via separate databases or schemas.

The purpose of this control is to prevent information, including encrypted representations of information, produced by the actions of a prior user/role (or the actions of a process acting on behalf of a prior user/role) from being available to any current user/role (or current process) that obtains access to a shared system resource (e.g., registers, main memory, secondary storage) after the resource has been released back to the information system. Control of information in shared resources is also referred to as object reuse. Data used for the development and testing of applications often involves copying data from production.

Moving data is only a part of the challenge of protecting the data. When the data is moved, it should also be changed so sensitive information is not made available in development environments. With the Oracle Data Masking Pack for Oracle Enterprise Manager, organizations can comply with data privacy and protection mandates that restrict the use of actual customer data. With Oracle Data Masking Pack, sensitive information such as credit card or social security numbers can be replaced with realistic values, allowing production data to be safely used for development, testing, or sharing with out-source or off-shore partners for other nonproduction purposes. When used in conjunction with Oracle Enterprise Manager, it is easy to develop a secure process which is capable of obfuscating the data during the movement process. If the Oracle Data Masking Pack and Enterprise Manager are not available, develop site-specific procedures to manage and obfuscate sensitive data.

Invalid user input occurs when a user inserts data or characters into an application's data entry fields and the application is unprepared to process that data. This results in unanticipated application behavior, potentially leading to an application or information system compromise. Invalid user input is one of the primary methods employed when attempting to compromise an application. All applications need to validate the data users attempt to input to the application for processing. Rules for checking the valid syntax and semantics of information system inputs (e.g., character set, length, numerical range, acceptable values) are in place to verify inputs match specified definitions for format and content. Inputs passed to interpreters are prescreened to prevent the content from being unintentionally interpreted as commands. This calls for inspection of application source code, which will require collaboration with the application developers. It is recognized that in many cases, the database administrator (DBA) is organizationally separate from the application developers and may have limited, if any, access to source code. Nevertheless, protections of this type are so important to the secure operation of databases that they must not be ignored. At a minimum, the DBA must attempt to obtain assurances from the development organization that this issue has been addressed and must document what has been discovered.

Checks: C-21509r307201_chk

Review DBMS code, settings, field definitions, constraints and triggers to determine whether or not data being input into the database is validated. If code exists that allows invalid data to be acted upon or input into the database, this is a finding. If field definitions do not exist in the database, this is a finding. If fields do not contain enabled constraints where required, this is a finding. - - - - - Oracle provides built-in processes to keep data and its integrity intact by using constraints. Integrity Constraint States You can specify that a constraint is enabled (ENABLE) or disabled (DISABLE). If a constraint is enabled, data is checked as it is entered or updated in the database, and data that does not conform to the constraint is prevented from being entered. If a constraint is disabled, then data that does not conform can be allowed to enter the database. Additionally, you can specify that existing data in the table must conform to the constraint (VALIDATE). Conversely, if you specify NOVALIDATE, you are not ensured that existing data conforms. An integrity constraint defined on a table can be in one of the following states: ENABLE, VALIDATE ENABLE, NOVALIDATE DISABLE, VALIDATE DISABLE, NOVALIDATE For details about the meaning of these states and an understanding of their consequences, see the Oracle Database SQL Language Reference. Some of these consequences are discussed here. Disabling Constraints To enforce the rules defined by integrity constraints, the constraints should always be enabled. However, consider temporarily disabling the integrity constraints of a table for the following performance reasons: - When loading large amounts of data into a table - When performing batch operations that make massive changes to a table (for example, changing every employee's number by adding 1000 to the existing number) - When importing or exporting one table at a time In all three cases, temporarily disabling integrity constraints can improve the performance of the operation, especially in data warehouse configurations. It is possible to enter data that violates a constraint while that constraint is disabled. Thus, you should always enable the constraint after completing any of the operations listed in the preceding bullet list. Enabling Constraints While a constraint is enabled, no row violating the constraint can be inserted into the table. However, while the constraint is disabled, such a row can be inserted. This row is known as an exception to the constraint. If the constraint is in the enable nonvalidated state, violations resulting from data entered while the constraint was disabled remain. The rows that violate the constraint must be either updated or deleted in order for the constraint to be put in the validated state. You can identify exceptions to a specific integrity constraint while attempting to enable the constraint. See "Reporting Constraint Exceptions". All rows violating constraints are noted in an EXCEPTIONS table, which you can examine. Enable Nonvalidate Constraint State When a constraint is in the enable nonvalidate state, all subsequent statements are checked for conformity to the constraint. However, any existing data in the table is not checked. A table with enable nonvalidated constraints can contain invalid data, but it is not possible to add new invalid data to it. Enabling constraints in the nonvalidated state is most useful in data warehouse configurations that are uploading valid OLTP data. Enabling a constraint does not require validation. Enabling a constraint nonvalidate is much faster than enabling and validating a constraint. Also, validating a constraint that is already enabled does not require any DML locks during validation (unlike validating a previously disabled constraint). Enforcement guarantees that no violations are introduced during the validation. Hence, enabling without validating enables you to reduce the downtime typically associated with enabling a constraint. Efficient Use of Integrity Constraints: A Procedure Using integrity constraint states in the following order can ensure the best benefits: Disable state. Perform the operation (load, export, import). Enable nonvalidate state. Enable state. Some benefits of using constraints in this order are: No locks are held. All constraints can go to enable state concurrently. Constraint enabling is done in parallel. Concurrent activity on table is permitted. Setting Integrity Constraints Upon Definition When an integrity constraint is defined in a CREATE TABLE or ALTER TABLE statement, it can be enabled, disabled, or validated or not validated as determined by your specification of the ENABLE/DISABLE clause. If the ENABLE/DISABLE clause is not specified in a constraint definition, the database automatically enables and validates the constraint. Disabling Constraints Upon Definition The following CREATE TABLE and ALTER TABLE statements both define and disable integrity constraints: CREATE TABLE emp ( empno NUMBER(5) PRIMARY KEY DISABLE, . . . ; ALTER TABLE emp ADD PRIMARY KEY (empno) DISABLE; An ALTER TABLE statement that defines and disables an integrity constraint never fails because of rows in the table that violate the integrity constraint. The definition of the constraint is allowed because its rule is not enforced. Enabling Constraints Upon Definition The following CREATE TABLE and ALTER TABLE statements both define and enable integrity constraints: CREATE TABLE emp ( empno NUMBER(5) CONSTRAINT emp.pk PRIMARY KEY, . . . ; ALTER TABLE emp ADD CONSTRAINT emp.pk PRIMARY KEY (empno); An ALTER TABLE statement that defines and attempts to enable an integrity constraint can fail because rows of the table violate the integrity constraint. If this case, the statement is rolled back, and the constraint definition is not stored and not enabled. When you enable a UNIQUE or PRIMARY KEY constraint an associated index is created.

Fix: F-21508r307202_fix

Modify database code to properly validate data before it is put into the database or acted upon by the database. Modify database to contain field definitions for each field in the database. Modify database to contain constraints on database columns and tables that require them for data validity. Review the application schemas implemented on the system. Check the DDL for the tables that are created for the applications to see if constraints have been enabled. - - - - - Enabling Constraints Upon Definition The following CREATE TABLE and ALTER TABLE statements both define and enable integrity constraints: CREATE TABLE emp ( empno NUMBER(5) CONSTRAINT emp.pk PRIMARY KEY, . . . ) ; ALTER TABLE emp ADD CONSTRAINT emp.pk PRIMARY KEY (empno); An ALTER TABLE statement that defines and attempts to enable an integrity constraint can fail because existing rows of the table violate the integrity constraint.

Any application providing too much information in error logs and in administrative messages to the screen risks compromising the data and security of the application and system. The structure and content of error messages needs to be carefully considered by the organization and development team. The extent to which the application is able to identify and handle error conditions is guided by organizational policy and operational requirements. Sensitive information includes account numbers, social security numbers, and credit card numbers. Databases can inadvertently provide a wealth of information to an attacker through improperly handled error messages. In addition to sensitive business or personal information, database errors can provide host names, IP addresses, user names, and other system information not required for troubleshooting but very useful to someone targeting the system. This calls for inspection of application source code, which will require collaboration with the application developers. It is recognized that in many cases, the database administrator (DBA) is organizationally separate from the application developers, and may have limited, if any, access to source code. Nevertheless, protections of this type are so important to the secure operation of databases that they must not be ignored. At a minimum, the DBA must attempt to obtain assurances from the development organization that this issue has been addressed, and must document what has been discovered.

Check DBMS settings and custom database and application code to verify error messages do not contain information beyond what is needed for troubleshooting the issue. If database errors contain PII data, sensitive business data, or information useful for identifying the host system, this is a finding. (Notes on Oracle's approach to this issue: Out of the box, Oracle covers this. For example, if a user does not have access to a table, the error is just that the table or view does not exist. The Oracle database is not going to display a Social Security Number in an error code unless an application is programmed to do so. Oracle applications will not expose the actual transactional data to a screen. The only way Oracle will capture this information is to enable specific logging levels. Custom code would require a review to ensure compliance.)

If the application provides too much information in error logs and administrative messages to the screen, this could lead to compromise. The structure and content of error messages need to be carefully considered by the organization and development team. The extent to which the information system is able to identify and handle error conditions is guided by organizational policy and operational requirements. Some default DBMS error messages can contain information that could aid an attacker in, among others things, identifying the database type, host address, or state of the database. Custom errors may contain sensitive customer information. It is important that error messages are displayed only to those who are authorized to view them. This calls for inspection of application source code, which will require collaboration with the application developers.

(If the application is coded in Oracle PL/SQL, the EXCEPTION block can be used to suppress or divert error messages. Most other programming languages provide comparable facilities, such as TRY ... CATCH.) ii) For each unauthorized user of each tool, remove the ability to access it. For each tool where access to DBMS error messages is not required and can be configured, suppress the messages. For each role/user that needs access to the error messages, or needs a tool where the messages cannot be suppressed, document the need in the system security plan.

The SRG states: "To prevent the compromise of authentication information, such as passwords, during the authentication process, the feedback from the information system shall not provide any information that would allow an unauthorized user to compromise the authentication mechanism." "Obfuscation of user-provided information when typed into the system is a method used in addressing this risk."

"Database applications may allow for entry of the account name and password as a visible parameter of the application execution command. This practice should be prohibited and disabled to prevent shoulder surfing." SQL*Plus is an essential part of any Oracle installation. SQL*Plus cannot be configured not to accept a plain-text password. Since the typical SQL*Plus user is a database administrator, the consequences of password compromise are particularly serious. Therefore, the use of plain-text passwords must be prohibited, as a matter of practice and procedure.

Oracle provides the capability to provide for a secure external password facility. Use the Oracle mkstore to create a secure storage area for passwords for applications, batch jobs and scripts to use or deploy a site-authorized facility to perform this function. Check to see what has been stored in the Oracle External Password Store. To view all contents of a client wallet external password store, check specific credentials by viewing them. Listing the external password store contents provides information you can use to decide whether to add or delete credentials from the store. To list the contents of the external password store, enter the following command at the command line: $ mkstore -wrl wallet_location -listCredential For example: $ mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -listCredential The wallet_location specifies the path to the directory where the wallet, whose external password store contents you want to view, is located. This command lists all of the credential database service names (aliases) and the corresponding user name (schema) for that database. Passwords are not listed. Configuring Clients to Use the External Password Store: If your client is already configured to use external authentication, such as Windows native authentication or Transport Layer Security (TLS), then Oracle Database uses that authentication method. The same credentials used for this type of authentication are typically also used to log in to the database. For clients not using such authentication methods or wanting to override them for database authentication, you can set the SQLNET.WALLET_OVERRIDE parameter in sqlnet.ora to TRUE. The default value for SQLNET.WALLET_OVERRIDE is FALSE, allowing standard use of authentication credentials as before. If you want a client to use the secure external password store feature, then perform the following configuration task: 1. Create a wallet on the client by using the following syntax at the command line: mkstore -wrl wallet_location -create For example: mkstore -wrl c:\oracle\product\12.1.0\db_1\wallets -create Enter password: password The wallet_location is the path to the directory where you want to create and store the wallet. This command creates an Oracle wallet with the autologin feature enabled at the location you specify. The autologin feature enables the client to access the wallet contents without supplying a password. The mkstore utility -create option uses password complexity verification. 2. Create database connection credentials in the wallet by using the following syntax at the command line: mkstore -wrl wallet_location -createCredential db_connect_string username Enter password: password For example: mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -createCredential oracle system Enter password: password In this specification: The wallet_location is the path to the directory where you created the wallet. The db_connect_string used in the CONNECT /@db_connect_string statement must be identical to the db_connect_string specified in the -createCredential command. The db_connect_string is the TNS alias you use to specify the database in the tnsnames.ora file or any service name you use to identify the database on an Oracle network. By default, tnsnames.ora is located in the $ORACLE_HOME/network/admin directory on UNIX systems and in ORACLE_HOME\network\admin on Windows. The username is the database logon credential. When prompted, enter the password for this user. 3. In the client sqlnet.ora file, enter the WALLET_LOCATION parameter and set it to the directory location of the wallet you created in Step 1. For example, if you created the wallet in $ORACLE_HOME/network/admin and your Oracle home is set to /private/ora11, then you need to enter the following into your client sqlnet.ora file: WALLET_LOCATION = (SOURCE = (METHOD = FILE) (METHOD_DATA = (DIRECTORY = /private/ora11/network/admin) ) ) 4. In the client sqlnet.ora file, enter the SQLNET.WALLET_OVERRIDE parameter and set it to TRUE as follows: SQLNET.WALLET_OVERRIDE = TRUE This setting causes all CONNECT /@db_connect_string statements to use the information in the wallet at the specified location to authenticate to databases. When external authentication is in use, an authenticated user with such a wallet can use the CONNECT /@db_connect_string syntax to access the previously specified databases without providing a user name and password. However, if a user fails that external authentication, then these connect statements also fail. Below is a sample sqlnet.ora file with the WALLET_LOCATION and the SQLNET.WALLET_OVERRIDE parameters set as described in Steps 3 and 4. Below is a sample SQLNET.ORA File with Wallet Parameters set: WALLET_LOCATION = (SOURCE = (METHOD = FILE) (METHOD_DATA = (DIRECTORY = /private/ora12/network/admin) ) ) SQLNET.WALLET_OVERRIDE = TRUE SSL_CLIENT_AUTHENTICATION = FALSE SSL_VERSION =1.2 (Note: This assumes that a single sqlnet.ora file, in the default location, is in use. Please see the supplemental file "Non-default sqlnet.ora configurations.pdf" for how to find multiple and/or differently located sqlnet.ora files.)

It is critical when a system is at risk of failing to process audit logs as required; it detects and takes action to mitigate the failure. Audit processing failures include: software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. Applications are required to be capable of either directly performing or calling system-level functionality performing defined actions upon detection of an application audit log processing failure. The Security Requirements Guide says, "A failure of database auditing will result in either the database continuing to function without auditing or in a complete halt to database operations. The database must be capable of taking organization-defined actions to avoid either a complete halt to processing or processing transactions in an unaudited manner." This STIG requirement mandates the implementation of a method to mitigate Oracle's inability to automatically reuse audit trail space on a first-in, first-out basis.

When dealing with change control issues, it should be noted, any changes to the hardware, software, and/or firmware components of the information system and/or application can potentially have significant effects on the overall security of the system. If the application were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. This requirement is contingent upon the language in which the application is programmed, as many application architectures in use today incorporate their software libraries into, and make them inseparable from, their compiled distributions, rendering them static and version-dependent.

When dealing with change control issues, it should be noted, any changes to the hardware, software, and/or firmware components of the information system and/or application can potentially have significant effects on the overall security of the system. Multiple applications can provide a cumulative negative effect. A vulnerability and subsequent exploit to one application can lead to an exploit of other applications sharing the same security context. For example, an exploit to a web server process that leads to unauthorized administrative access to host system directories can most likely lead to a compromise of all applications hosted by the same system. Database software not installed using dedicated directories both threatens and is threatened by other hosted applications. Access controls defined for one application may by default provide access to the other application's database objects or directories. Any method that provides any level of separation of security context assists in the protection between applications.

Non-organizational users include all information system users other than organizational users which include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors, guest researchers, individuals from allied nations). Non-organizational users shall be uniquely identified and authenticated for all accesses other than those accesses explicitly identified and documented by the organization when related to the use of anonymous access, such as accessing a web server. Accordingly, a risk assessment is used in determining the authentication needs of the organization. Scalability, practicality, and security are simultaneously considered in balancing the need to ensure ease of use for access to federal information and information systems with the need to protect and adequately mitigate risk to organizational operations, organizational assets, individuals, other organizations, and the Nation.

Information system management functionality includes functions necessary to administer databases, network components, workstations, or servers, and typically requires privileged user access. The separation of user functionality from information system management functionality is either physical or logical and is accomplished by using different computers, different central processing units, different instances of the operating system, different network addresses, combinations of these methods, or other methods, as appropriate. An example of this type of separation is observed in web administrative interfaces that use separate authentication methods for users of any other information system resources. This may include isolating the administrative interface on a different domain and with additional access controls. If administrative functionality or information regarding DBMS management is presented on an interface available for users, information on DBMS settings may be inadvertently made available to the user.

Checks: C-21521r307237_chk

Check DBMS settings and vendor documentation to verify administrative functionality is separate from user functionality. If administrator and general user functionality is not separated either physically or logically, this is a finding.

Fix: F-21520r307238_fix

Configure DBMS settings to separate database administration and general user functionality. Provide those who have both administrative and general-user responsibilities with separate accounts for these separate functions.

The DBMS must protect against an individual using a group account from falsely denying having performed a particular action.

Non-repudiation of actions taken is required in order to maintain application integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e.g., indicating concurrence or signing a contract), and receiving a message. Non-repudiation protects individuals against later claims by an author of not having authored a particular document, a sender of not having transmitted a message, a receiver of not having received a message, or a signatory of not having signed a document. Group authentication does not provide individual accountability for actions taken on the DBMS or data. Whenever a single database account is used to connect to the database, a secondary authentication method that provides individual accountability is required. This scenario most frequently occurs when an externally hosted application authenticates individual users to the application and the application uses a single account to retrieve or update database information on behalf of the individual users. When group accounts are utilized without another means of identifying individual users, users may deny having performed a particular action. This calls for inspection of application source code, which will require collaboration with the application developers. It is recognized that in many cases, the database administrator (DBA) is organizationally separate from the application developers and may have limited, if any, access to source code. Nevertheless, protections of this type are so important to the secure operation of databases that they must not be ignored. At a minimum, the DBA must attempt to obtain assurances from the development organization that this issue has been addressed and must document what has been discovered.

Checks: C-21522r307240_chk

If there are no group accounts available to more than one user, this is not a finding. If a group account is used by an application to interact with the database, review the System Security Plan, the tables in the database, and the application source code/documentation to determine whether the application captures the individual user's identity and stores that identity along with all data inserted and updated (also with all records of reads and/or deletions, if these are required to be logged). If there are gaps in the application's ability to do this, and the gaps and the risk are not defined in the system documentation and accepted by the AO, this is a finding. If users are sharing a group account to log on to Oracle tools or third-party products that access the database, this is a finding. To ensure that user activities other than SELECT, INSERT, UPDATE and DELETE are also monitored and attributed to individuals, verify that Oracle auditing is enabled. To see if Oracle is configured to capture audit data, enter the following SQLPlus command: SHOW PARAMETER AUDIT_TRAIL or the following SQL query: SELECT * FROM SYS.V$PARAMETER WHERE NAME = 'audit_trail'; If Oracle returns the value 'NONE', this is a finding.

Fix: F-21521r307241_fix

Use accounts assigned to individual users where feasible. Configure DBMS to provide individual accountability at the DBMS level, and in audit logs, for actions performed under a shared database account. Modify applications and data tables that are not capturing individual user identity to do so. Create and enforce the use of individual user IDs for logging on to Oracle tools and third-party products. If Oracle (or third-party) auditing is not already enabled, enable it. For Oracle auditing, use this query: ALTER SYSTEM SET AUDIT_TRAIL=<audit trail type> SCOPE=SPFILE; Audit trail type can be 'OS', 'DB', 'DB,EXTENDED', 'XML' or 'XML,EXTENDED'. After executing this statement, it may be necessary to shut down and restart the Oracle database. For more information on the configuration of auditing, please refer to "Auditing Database Activity" in the Oracle Database 2 Day + Security Guide: http://docs.oracle.com/cd/E11882_01/server.112/e10575/tdpsg_auditing.htm and "Verifying Security Access with Auditing" in the Oracle Database Security Guide: http://docs.oracle.com/cd/E11882_01/network.112/e36292/auditing.htm#DBSEG006 and "27 DBMS_AUDIT_MGMT" in the Oracle Database PL/SQL Packages and Types Reference: http://docs.oracle.com/cd/E11882_01/appdev.112/e40758/d_audit_mgmt.htm If the site-specific audit requirements are not covered by the default audit options, deploy and configure Fine-Grained Auditing. For details, refer to Oracle documentation, at the locations above. If this level of auditing does not meet site-specific requirements, consider deploying the Oracle Audit Vault. The Audit Vault is a highly configurable option from Oracle made specifically for performing the audit functions. It has reporting capabilities as well as user-defined rules that provide additional flexibility for complex auditing requirements.

Oracle database products must be a version supported by the vendor.

Unsupported commercial and database systems should not be used because fixes to newly identified bugs will not be implemented by the vendor. The lack of support can result in potential vulnerabilities. Systems at unsupported servicing levels or releases will not receive security updates for new vulnerabilities, which leaves them subject to exploitation. When maintenance updates and patches are no longer available, the database software is no longer considered supported and should be upgraded or decommissioned.

Security faults with software applications and operating systems are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling, must also be addressed expeditiously. Anytime new software code is introduced to a system there is the potential for unintended consequences. There have been documented instances where the application of a patch has caused problems with system integrity or availability. Due to information system integrity and availability concerns, organizations must give careful consideration to the methodology used to carry out automatic updates. Unsupported software versions are not patched by vendors to address newly discovered security versions. An unpatched version is vulnerable to attack.

Checks: C-41643r667468_chk

Follow the vendor instruction for determining the product version number. View the vendor-provided list of supported versions. To be considered supported, the vendor must report that the version is supported by security patches to reported vulnerabilities. If the security patch support for the installed version cannot be determined or the version is not shown as supported, this is a finding. If the software does not contain the latest security patches, this is a finding. Oracle produces security patches on a quarterly basis on or about the fifteenth of the month. The first patch of a calendar year is delivered in January and then April, July and October respectively. There is an automated notice that is available to anyone with access to My Oracle Support. Check to see if the DBA or Administrator of the Oracle account at My Oracle Support is registered to receive the Oracle Security Patch notice. This notice is available to anyone with a valid My Oracle Support. The security notification contains information on the current security update and also the platforms and versions that will be supported by the next patch. For complete information on the availability of the security patch for your specific system, please refer to the Oracle Lifetime Support Policy. Check My Oracle Support for the latest Oracle Quarterly Patch Update patch number, and then check the inventory of the instance you are reviewing and see if the latest security patch is installed using the following command. Issue the following command: $ <ORACLE_HOME>/OPatch/opatch lsinventory -detail -oh <ORACLE_HOME> Check to see if the latest available patch is installed.

Preventing the disclosure of transmitted information requires that applications take measures to employ some form of cryptographic mechanism in order to protect the information during transmission. This is usually achieved through the use of Transport Layer Security (TLS), SSL VPN, or IPSEC tunnel. Alternative physical protection measures include Protected Distribution Systems (PDS). PDS are used to transmit unencrypted classified NSI through an area of lesser classification or control. Inasmuch as the classified NSI is unencrypted, the PDS must provide adequate electrical, electromagnetic, and physical safeguards to deter exploitation. Refer to NSTSSI No. 7003 for additional details on a PDS. Information in transmission is particularly vulnerable to attack. If the DBMS does not employ cryptographic mechanisms preventing unauthorized disclosure of information during transit, the information may be compromised.

Checks: C-41645r667474_chk

Check DBMS settings to determine whether cryptographic mechanisms are used to prevent the unauthorized disclosure of information during transmission. Determine whether physical measures are being used instead of cryptographic mechanisms. If neither cryptographic nor physical measures are being utilized, this is a finding.

This requirement is related to remote access, but more specifically to the networking protocols allowing systems to communicate. Remote access is any access to an organizational information system by a user (or an information system) communicating through an external, non-organization controlled network (e.g., the Internet). Examples of remote access methods include dial-up, broadband, and wireless. Some networking protocols allowing remote access may not meet security requirements to protect data and components. Bluetooth and peer-to-peer networking are examples of less than secure networking protocols. The DoD Ports, Protocols, and Services Management (PPSM) program provides implementation guidance on the use of IP protocols and application and data services traversing the DoD Networks in a manner supporting net-centric operations. Applications implementing or utilizing remote access network protocols need to ensure the application is developed and implemented in accordance with the PPSM requirements. In situations where it has been determined that specific operational requirements outweigh the risks of enabling an insecure network protocol, the organization may pursue a risk acceptance. Using protocols deemed non-secure would compromise the ability of the DBMS to operate in a secure fashion. The database must be able to disable network protocols deemed non-secure.

Checks: C-41646r667477_chk

Review the PPSM Technical Assurance List to acquire an up-to-date list of network protocols deemed non-secure. (For definitive information on Ports, Protocols and Services Management (PPSM), refer to http://iase.disa.mil/ppsm/index.html.) Review DBMS settings to determine if the database is utilizing any network protocols deemed non-secure. If the DBMS is not using any network protocols deemed non-secure, this is not a finding.. If the database is utilizing protocols specified as non-secure in the PPSM, verify the protocols are explicitly identified in the System Security Plan and that they are in support of specific operational requirements. If they are not identified in the SSP or are not supporting specific operational requirements, this is a finding. If non-secure network protocols are not being used but are not disabled in the DBMS's configuration, this is a finding. After determining the site-specific operational requirements and which protocols are explicitly defined in the System Security Plan, check the $TNS_ADMIN setting for the location of the Oracle listener.ora file. The listener.ora file is a configuration file for Oracle Net Listener that identifies the following: A unique name for the listener, typically LISTENER A protocol address that it is accepting connection requests on, and A service it is listening for. If the listener.ora file shows a PROTOCOL= statement and the PROTOCOL is deemed non-secure, that is a finding. LISTENER= (DESCRIPTION= (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=sale-server)(PORT=1521)) (ADDRESS=(PROTOCOL=ipc)(KEY=extproc)))) SID_LIST_LISTENER= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=sales.us.example.com) (ORACLE_HOME=/oracle11g) (SID_NAME=sales)) (SID_DESC= (SID_NAME=plsextproc) (ORACLE_HOME=/oracle11g) (PROGRAM=extproc))) Protocol Parameters The Oracle Listener and the Oracle Connection Manager are identified by protocol addresses. The information below contains the "Protocol-Specific Parameters" used by the Oracle protocol support. Protocol-Specific Parameters Protocol: IPC Parameter: PROTOCOL Notes: Specify ipc as the value. Protocol: IPC Parameter: KEY Notes: Specify a unique name for the service. Oracle recommends using the service name or SID of the service. Example: (PROTOCOL=ipc)(KEY=sales) Protocol: Named Pipes Parameter: PROTOCOL Notes: Specify nmp as the value. Protocol: Named Pipes Parameter: SERVER Notes: Specify the name of the Oracle server. Protocol: Named Pipes Parameter: PIPE Notes: Specify the pipe name used to connect to the database server. This is the same PIPE keyword specified on the server with Named Pipes. This name can be any name. Example: (Protocol=nmp) (SERVER=USDOD) (PIPE=dbpipe01) Protocol: SDP Parameter: PROTOCOL Notes: Specify sdp as the value. Protocol: SDP Parameter: HOST Notes: Specify the host name or IP address of the computer. Protocol: SDP Parameter: PORT Notes: Specify the listening port number. Example: (PROTOCOL=sdp)(HOST=sales-server)(PORT=1521) (PROTOCOL=sdp)(HOST=192.168.2.204)(PORT=1521) Protocol: TCP/IP Parameter: PROTOCOL Notes: Specify TCP as the value. Protocol: TCP/IP Parameter: HOST Notes: Specify the host name or IP address of the computer. Protocol: TCP/IP Parameter: PORT Notes: Specify the listening port number. Example: (PROTOCOL=tcp)(HOST=sales-server)(PORT=1521) (PROTOCOL=tcp)(HOST=192.168.2.204)(PORT=1521) Protocol: TCP/IP with SSL Parameter: PROTOCOL Notes: Specify tcps as the value. Protocol: TCP/IP with SSL Parameter: HOST Notes: Specify the host name or IP address of the computer. Protocol: TCP/IP with SSL Parameter: PORT Notes: Specify the listening port number.

Disable any network protocol listed as non-secure in the PPSM documentation. To disable the protocol deemed not secure, stop the listener by issuing the following command as the Oracle Software owner, typically Oracle. $ lsnrctl stop This will stop the listener. Edit the LISTENER.ORA file and remove the protocols deemed not secure and restart the listener. For example, if TCP was deemed as not secure and the listener.ora would need to be changed and the tcp entry would need to be removed. That would only allow the listener to listen for an IPC connection. LISTENER= (DESCRIPTION= (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=sale-server)(PORT=1521)) - remove this line and properly balance the parentheses - (ADDRESS=(PROTOCOL=ipc)(KEY=extproc)))) SID_LIST_LISTENER= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=sales.us.example.com) (ORACLE_HOME=/oracle11g) (SID_NAME=sales)) (SID_DESC= (SID_NAME=plsextproc) (ORACLE_HOME=/oracle11g) (PROGRAM=extproc))) Revise the client side TNSNAMES.ORA to align the PROTOCOL value in the PROTOCOL portion of the connect string. For example, if TCP was deemed as not secure and the listener.ora was changed to listen for an IPC connection the code below would be required: net_service_name= (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=sales1-svr)(PORT=1521)) (ADDRESS=(PROTOCOL=tcp)(HOST=sales2-svr)(PORT=1521)) (CONNECT_DATA= (SERVICE_NAME=sales.us.example.com)))

Temporary application accounts could be used in the event of a vendor support visit where a support representative requires a temporary unique account in order to perform diagnostic testing or conduct some other support-related activity. When these types of accounts are created, there is a risk that the temporary account may remain in place and active after the support representative has left. To address this, in the event temporary application accounts are required, the application must ensure accounts designated as temporary in nature shall automatically terminate these accounts after an organization-defined time period. Such a process and capability greatly reduces the risk that accounts will be misused, hijacked, or data compromised. Note: User authentication and account management should be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP. This requirement applies to cases where it is necessary to have accounts directly managed by Oracle. Temporary database accounts must be identified in order for the system to recognize and terminate them after a given time period. The DBMS and any administrators must have a means to recognize any temporary accounts for special handling.

Checks: C-41647r667480_chk

If the organization has a policy, consistently enforced, forbidding the creation of emergency or temporary accounts, this is not a finding. If all user accounts are authenticated by the OS or an enterprise-level authentication/access mechanism, and not by Oracle, this is not a finding. If using database mechanisms to satisfy this requirement, look for a profile for use with temporary accounts. To obtain a list of profiles: SELECT PROFILE#, NAME FROM SYS.PROFNAME$; To obtain a list of users assigned a given profile (TEMPORARY_USERS, in this example): SELECT USERNAME, PROFILE FROM SYS.DBA_USERS WHERE PROFILE = 'TEMPORARY_USERS' ORDER BY USERNAME; To obtain a list of users that have NOT been assigned the DEFAULT (the resulting list of profiles can be quickly scanned for any profile like TEMPORARY, in this example): SELECT USERNAME, PROFILE FROM SYS.DBA_USERS WHERE PROFILE <> 'DEFAULT' ORDER BY PROFILE; If no profile for temporary accounts can be identified, this is not a finding.

Fix: F-41606r667481_fix

Use a profile with a distinctive name (for example, TEMPORARY_USERS), so that temporary users can be easily identified. Whenever a temporary user account is created, assign it to this profile. Set values in the profile as needed for temporary users - see below for further information.

CPU_PER_SESSION - Specify the CPU time limit for a session, expressed in hundredths of seconds. CPU_PER_CALL - Specify the CPU time limit for a call (a parse, execute, or fetch), expressed in hundredths of seconds. CONNECT_TIME - Specify the total elapsed time limit for a session, expressed in minutes. IDLE_TIME - Specify the permitted periods of continuous inactive time during a session, expressed in minutes. Long-running queries and other operations are not subject to this limit. LOGICAL_READS_PER_SESSION - Specify the permitted number of data blocks read in a session, including blocks read from memory and disk. LOGICAL_READS_PER_CALL - Specify the permitted number of data blocks read for a call to process a SQL statement (a parse, execute, or fetch). PRIVATE_SGA - Specify the amount of private space a session can allocate in the shared pool of the system global area (SGA). Refer to size_clause for information on that clause. COMPOSITE_LIMIT - See Oracle documentation for more details. Password Parameters: Use the following clauses to set password parameters. Parameters that set lengths of time are interpreted in number of days. For testing purposes you can specify minutes (n/1440) or even seconds (n/86400). FAILED_LOGIN_ATTEMPTS - Specify the number of failed attempts to log in to the user account before the account is locked. PASSWORD_LIFE_TIME - Specify the number of days the same password can be used for authentication. If you also set a value for PASSWORD_GRACE_TIME, then the password expires if it is not changed within the grace period, and further connections are rejected. If you omit this clause, then the default is 180 days. PASSWORD_REUSE_TIME and PASSWORD_REUSE_MAX - These two parameters must be set in conjunction with each other. PASSWORD_REUSE_TIME specifies the number of days before which a password cannot be reused. PASSWORD_REUSE_MAX specifies the number of password changes required before the current password can be reused. For these parameters to have any effect, you must specify an integer for both of them. If you specify an integer for both of these parameters, then the user cannot reuse a password until the password has been changed the number of times specified for PASSWORD_REUSE_MAX during the number of days specified for PASSWORD_REUSE_TIME. For example, if you specify PASSWORD_REUSE_TIME to 30 and PASSWORD_REUSE_MAX to 10, then the user can reuse the password after 30 days if the password has already been changed 10 times. If you specify an integer for either of these parameters and specify UNLIMITED for the other, then the user can never reuse a password. If you specify DEFAULT for either parameter, then Oracle Database uses the value defined in the DEFAULT profile. By default, all parameters are set to UNLIMITED in the DEFAULT profile. If you have not changed the default setting of UNLIMITED in the DEFAULT profile, then the database treats the value for that parameter as UNLIMITED. If you set both of these parameters to UNLIMITED, then the database ignores both of them. This is the default if you omit both parameters. PASSWORD_LOCK_TIME - Specify the number of days an account will be locked after the specified number of consecutive failed logon attempts. If you omit this clause, then the default is 1 day. PASSWORD_GRACE_TIME - Specify the number of days after the grace period begins during which a warning is issued and logon is allowed. If you omit this clause, then the default is 7 days. PASSWORD_VERIFY_FUNCTION - lets a PL/SQL password complexity verification script be passed as an argument to the CREATE PROFILE statement. Oracle Database provides a default script, but you can create your own routine or use third-party software instead.

The DBMS must provide a mechanism to automatically terminate accounts designated as temporary or emergency accounts after an organization-defined time period.

Temporary application accounts could ostensibly be used in the event of a vendor support visit where a support representative requires a temporary unique account in order to perform diagnostic testing or conduct some other support related activity. When these types of accounts are created, there is a risk that the temporary account may remain in place and active after the support representative has left. To address this, in the event temporary application accounts are required, the application must ensure accounts designated as temporary in nature shall automatically terminate these accounts after an organization-defined time period. Such a process and capability greatly reduces the risk that accounts will be misused, hijacked, or data compromised. User authentication and account management should be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP. This requirement applies to cases where it is necessary to have accounts directly managed by Oracle. Temporary database accounts must be automatically terminated after an organization-defined time period in order to mitigate the risk of the account being used beyond its original purpose or timeframe.

Checks: C-41648r667483_chk

If the organization has a policy, consistently enforced, forbidding the creation of emergency or temporary accounts, this is not a finding. If all user accounts are authenticated by the OS or an enterprise-level authentication/access mechanism, and not by Oracle, this is not a finding. Check DBMS settings, OS settings, and/or enterprise-level authentication/access mechanisms settings to determine if the site utilizes a mechanism whereby temporary or emergency accounts can be terminated after an organization-defined time period. If not, this is a finding. Check the profiles to see what the password_life_time is set to in the table dba_profiles. The password_life_time is a value stored in the LIMIT column, and identified by the value PASSWORD_LIFE_TIME in the RESOURCE_NAME column. SQL>select profile, resource_name, resource_type, limit from dba_profiles where upper(resource_name) like 'PASSWORD_LIFE_TIME'; Verify that the user in question is assigned to a profile with the PASSWORD_LIFE_TIME set to the amount of time the user is expected to be using the password. If not, this is a finding.

Fix: F-41607r667484_fix

If all user accounts are authenticated by the OS or an enterprise-level authentication/access mechanism, and not by Oracle, no fix to the DBMS is required. If using database mechanisms to satisfy this requirement, use a profile with a distinctive name (for example, TEMPORARY_USERS), so that temporary users can be easily identified. Whenever a temporary user account is created, assign it to this profile. Create a job to lock accounts under this profile that are more than n days old, where n is the organization-defined time period.

The DBMS must enforce Discretionary Access Control (DAC) policy allowing users to specify and control sharing by named individuals, groups of individuals, or by both, limiting propagation of access rights and includes or excludes access to the granularity of a single user.

Access control policies (e.g., identity-based policies, role-based policies, attribute-based policies) and access enforcement mechanisms (e.g., access control lists, access control matrices, cryptography) are employed by organizations to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, domains). DAC is a type of access control methodology serving as a means of restricting access to objects and data based on the identity of subjects and/or groups to which they belong. It is discretionary in the sense that application users with the appropriate permissions to access an application resource or data have the discretion to pass that permission on to another user either directly or indirectly. Data protection requirements may result in a DAC policy being specified as part of the application design. Discretionary access controls would be employed at the application level to restrict and control access to application objects and data thereby providing increased information security for the organization. When DAC controls are employed, those controls must limit sharing to named application users, groups of users, or both. The application DAC controls must also limit the propagation of access rights and have the ability to exclude access to data down to the granularity of a single user. Databases using DAC must have the ability for the owner of an object or information to assign or revoke rights to view or modify the object or information. If the owner of an object or information does not have rights to exclude access to an object or information at a user level, users may gain access to objects and information they are not authorized to view/modify.

Checks: C-41649r667486_chk

Check DBMS settings to determine if users are able to assign and revoke rights to the objects and information that they own. If users cannot assign or revoke rights to the objects and information that they own to groups, roles, or individual users, this is a finding.

Fix: F-41608r667487_fix

Modify DBMS settings to allow users to assign or revoke access rights to objects and information owned by the user. The ability to grant or revoke rights must include the ability to grant or revoke those rights down to the granularity of a single user. (Note: in most cases no fix will be necessary. This is default functionality for Oracle.)

The DBMS must restrict grants to sensitive information to authorized user roles.

Applications employ the concept of least privilege for specific duties and information systems (including specific functions, ports, protocols, and services). The concept of least privilege is also applied to information system processes, ensuring that the processes operate at privilege levels no higher than necessary to accomplish required organizational missions and/or functions. Organizations consider the creation of additional processes, roles, and information system accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of information systems. Unauthorized access to sensitive data may compromise the confidentiality of personnel privacy, threaten national security, or compromise a variety of other sensitive operations.

Use of privileged accounts for non-administrative purposes puts data at risk of unintended or unauthorized loss, modification, or exposure. In particular, DBA accounts if used for non-administration application development or application maintenance can lead to miss-assignment of privileges where privileges are inherited by object owners. It may also lead to loss or compromise of application data where the elevated privileges bypass controls designed in and provided by applications. External applications called or spawned by the DBMS process may be executed under OS accounts with unnecessary privileges.

Anytime an authentication method is exposed, to allow for the utilization of an application, there is a risk that attempts will be made to obtain unauthorized access. To defeat these attempts, organizations define the number of times a user account may consecutively fail a login attempt. The organization also defines the period of time in which these consecutive failed attempts may occur. By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute forcing, is reduced. Limits are imposed by locking the account. More recent brute force attacks make attempts over long periods of time to circumvent intrusion detection systems and system account lockouts based entirely on the number of failed logins that are typically reset after a successful login. Note that user authentication and account management must be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP This requirement applies to cases where it is necessary to have accounts directly managed by Oracle. Note also that a policy that places no limit on the length of the timeframe (for counting consecutive invalid attempts) does satisfy this requirement.

(This addresses both O112-C2-005000 and O112-C2-005200.) The limit on the number of consecutive failed logon attempts is defined in the profile assigned to a user. To see what profile is assigned to a user, enter the following query: SQL>SELECT profile FROM dba_users WHERE username = '&USERNAME' This will return the profile name assigned to that user. Now check the values assigned to the profile returned from the query above: SQL>SELECT PROFILE, RESOURCE_NAME, LIMIT FROM DBA_PROFILES WHERE PROFILE LIKE '&PROFILE_NAME' Check the settings for failed_login_attempts - this is the number of consecutive failed login attempts before locking the Oracle user account. If the value is greater than 3, this is a finding.

Discretionary Access Control (DAC) is based on the premise that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which mode (e.g., read or write). Ownership is usually acquired as a consequence of creating the object or via specified ownership assignment. DAC allows the owner to determine who will have access to objects they control. An example of DAC includes user-controlled file permissions. DAC models have the potential for the access controls to propagate without limit, resulting in unauthorized access to said objects. When applications provide a discretionary access control mechanism, the application must be able to limit the propagation of those access rights. The DBMS must ensure the recipient of permissions possesses only the access intended. The database must enforce the ability to limit rights propagation if that is the intent of the grantor. If the propagation of access rights is not limited, users with rights to objects they do not own can continue to grant rights to those objects to other users without limit. This is default for behavior for Oracle.

Checks: C-41661r667522_chk

Verify the DBMS has the ability to grant permissions without the grantee receiving the right to grant those same permissions to another user. Review organization policies regarding access propagation. If an access propagation policy limiting the propagation of rights does not exist, this is a finding. Review DBMS configuration to verify access propagation policies are enforced by the DBMS as configured. If the DBMS does not enforce the access propagation policy, this is a finding.

Fix: F-41620r667523_fix

Create and document an access propagation policy that limits the propagation of rights. Configure the DBMS to enforce the access propagation policy. When a user is granted access to an object they have access to the object. When a used is granted access to an object with the ADMIN option, then they can provide permissions to others. Without the ADMIN option, a user cannot grant access to an object. No configuration is required.

A DBMS utilizing Discretionary Access Control (DAC) must enforce a policy that includes or excludes access to the granularity of a single user.

DAC is based on the notion that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which mode (e.g., read or write). Ownership is usually acquired as a consequence of creating the object or via specified ownership assignment. DAC allows the owner to determine who will have access to objects they control. An example of DAC includes user-controlled file permissions. Including or excluding access to the granularity of a single user means providing the capability to either allow or deny access to objects (e.g., files, folders) on a per single user basis. Databases using DAC must have the ability for the owner of an object or information to assign or revoke rights to view or modify the object or information. If the owner of an object or information does not have rights to exclude access to an object or information at a user level, users may gain access to objects and information they are not authorized to view/modify.

Checks: C-41662r667525_chk

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Audit processing failures include: software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. If audit log capacity were to be exceeded, then events subsequently occurring would not be recorded. Organizations shall define a maximum allowable percentage of storage capacity serving as an alarming threshold (e.g., application has exceeded 80% of log storage capacity allocated) at which time the application or the logging mechanism the application utilizes will provide a warning to the appropriate personnel. A failure of database auditing will result in either the database continuing to function without auditing or in a complete halt to database operations. When audit processing fails, appropriate personnel must be alerted immediately to avoid further downtime or unaudited transactions. This can be an alert provided by the database, a log repository, or the OS when a designated log directory is nearing capacity.

Checks: C-41663r667528_chk

Review DBMS, OS, or third-party logging application settings to determine whether a warning will be provided when a specific percentage of log storage capacity is reached. If no warning will be provided, this is a finding.

Modify DBMS, OS, or third-party logging application settings to alert appropriate personnel when a specific percentage of log storage capacity is reached. For ease of management, it is recommended that the audit tables be kept in a dedicated tablespace. If Oracle Enterprise Manager is in use, the capability to issue such an alert is built in and configurable via the console so an email can be sent to a designated administrator. If Enterprise Manager is unavailable, the following script can be used to monitor storage space; this can be combined with additional code to email the appropriate administrator so they can take action. sqlplus connect as sysdba SQL> set pagesize 300 SQL> set linesize 120 SQL> column sumb format 9,999,999,999,999 SQL> column extents format 999999 SQL> column bytes format 9,999,999,999,999 SQL> column largest format 9,999,999,999,999 SQL> column Tot_Size format 9,999,999,999,999 SQL> column Tot_Free format 9,999,999,999,999 SQL> column Pct_Free format 9,999,999,999,999 SQL> column Chunks_Free format 9,999,999,999,999 SQL> column Max_Free format 9,999,999,999,999 SQL> set echo off SQL> spool TSINFO.txt SQL> PROMPT SPACE AVAILABLE IN TABLESPACES SQL> select a.tablespace_name,sum(a.tots) Tot_Size, SQL> sum(a.sumb) Tot_Free, SQL> sum(a.sumb)*100/sum(a.tots) Pct_Free, SQL> sum(a.largest) Max_Free,sum(a.chunks) Chunks_Free SQL> from SQL> ( SQL> select tablespace_name,0 tots,sum(bytes) sumb, SQL> max(bytes) largest,count(*) chunks SQL> from dba_free_space a SQL> group by tablespace_name SQL> union SQL> select tablespace_name,sum(bytes) tots,0,0,0 from SQL> dba_data_files SQL> group by tablespace_name) a SQL> group by a.tablespace_name; Sample Output SPACE AVAILABLE IN TABLESPACES TABLESPACE_NAME TOT_SIZE TOT_FREE PCT_FREE MAX_FREE CHUNKS_FREE ------------------------------ ------------ ------------ ------------ ------------ ------------ DES2 41,943,040 30,935,040 74 30,935,040 1 DES2_I 31,457,280 23,396,352 74 23,396,352 1 RBS 60,817,408 57,085,952 94 52,426,752 16 SYSTEM 94,371,840 5,386,240 6 5,013,504 3 TEMP 563,200 561,152 100 133,120 5 TOOLS 120,586,240 89,407,488 74 78,190,592 12 USERS 1,048,576 26,624 3 26,624 1

When dealing with access restrictions pertaining to change control, it should be noted any changes to the hardware, software, and/or firmware components of the information system and/or application can have significant effects on the overall security of the system. Accordingly, only qualified and authorized individuals must be allowed to obtain access to application components for the purposes of initiating changes, including upgrades and modifications. Modifications to the DBMS settings, the database files, database configuration files, or the underlying database application files themselves could have catastrophic consequences to the database. Modification to DBMS settings could include turning off access controls to the database, the halting of archiving, the halting of auditing, and any number of other malicious actions.

Review the database backup procedures and implementation evidence. Evidence of implementation includes records of backup events and physical review of backup media. Evidence should match the backup plan as recorded in the system documentation. If backup procedures do not exist or are not implemented in accordance with the procedures, this is a finding. - - - - - The Oracle recommended process for backup and recovery is Oracle RMAN. If Oracle RMAN is deployed, execute the following commands to ensure that the evidence of the implementation of the backup policy includes validating that the files are restorable: Validating Database Files with BACKUP VALIDATE --You can use the BACKUP VALIDATE command to do the following: -- Check datafiles for physical and logical block corruption -- Confirm that all database files exist and are in the correct locations --When you run BACKUP VALIDATE, RMAN reads the files to be backed up in their entirety, as it would during a real backup. RMAN does not, however, actually produce any backup sets or image copies. --You cannot use the BACKUPSET, MAXCORRUPT, or PROXY parameters with BACKUP VALIDATE. --To validate files with the BACKUP VALIDATE command: 1. Start RMAN and connect to a target database and recovery catalog (if used). 2. Run the BACKUP VALIDATE command. For example, you can validate that all database files and archived logs can be backed up by running a command as shown in the following example. This command checks for physical corruptions only. BACKUP VALIDATE DATABASE ARCHIVELOG ALL; To check for logical corruptions in addition to physical corruptions, run the following variation of the preceding command: BACKUP VALIDATE CHECK LOGICAL DATABASE ARCHIVELOG ALL; In the preceding examples, the RMAN client displays the same output that it would if it were really backing up the files. If RMAN cannot back up one or more of the files, then it issues an error message. Validating Backups Before Restoring Them You can run RESTORE ... VALIDATE to test whether RMAN can restore a specific file or set of files from a backup. RMAN chooses which backups to use. The database must be mounted or open for this command. You do not have to take datafiles offline when validating the restore of datafiles, because validation of backups of the datafiles only reads the backups and does not affect the production datafiles. When validating files on disk or tape, RMAN reads all blocks in the backup piece or image copy. RMAN also validates offsite backups. The validation is identical to a real restore operation except that RMAN does not write output files. To validate backups with the RESTORE command: 1. Run the RESTORE command with the VALIDATE option. This following example illustrates validating the restore of the database and all archived redo logs: RESTORE DATABASE VALIDATE; RESTORE ARCHIVELOG ALL VALIDATE; If you do not see an RMAN error stack, then skip the subsequent steps. The lack of error messages means that RMAN had confirmed that it can use these backups successfully during a real restore and recovery. 2. If you see error messages in the output and the RMAN-06026 message, then investigate the cause of the problem. If possible, correct the problem that is preventing RMAN from validating the backups and retry the validation. The following error means that RMAN cannot restore one or more of the specified files from your available backups: RMAN-06026: some targets not found - aborting restore The following sample output shows that RMAN encountered a problem reading the specified backup: RMAN-03009: failure of restore command on c1 channel at 12-DEC-06 23:22:30 ORA-19505: failed to identify file "oracle/dbs/1fafv9gl_1_1" ORA-27037: unable to obtain file status SVR4 Error: 2: No such file or directory Additional information: 3

Multifactor authentication is defined as using two or more factors to achieve authentication. Factors include: (i) Something a user knows (e.g., password/PIN); (ii) Something a user has (e.g., cryptographic identification device, token); or (iii) Something a user is (e.g., biometric). The DBMS must be configured to automatically utilize organization-level account management functions, and these functions must immediately enforce the organization's current account policy. The lack of multifactor authentication makes it much easier for an attacker to gain unauthorized access to a system. Transport Layer Security (TLS) is the successor protocol to Secure Sockets Layer (SSL). Although the Oracle configuration parameters have names including 'SSL', such as SSL_VERSION and SSL_CIPHER_SUITES, they refer to TLS. Use authentication to prove the identities of users who are attempting to log on to the database. Oracle Database enables strong authentication with Oracle authentication adapters that support various third-party authentication services, including TLS with digital certificates, as well as Smart Cards (CAC, PIV).

To assure individual accountability and prevent unauthorized access, application users (and any processes acting on behalf of users) must be individually identified and authenticated. A group authenticator is a generic account used by multiple individuals. Use of a group authenticator alone does not uniquely identify individual users. An example of a group authenticator is the UNIX OS 'root' user account, a Windows 'administrator' account, an 'SA' account, or a 'helpdesk' account. For example, the UNIX and Windows operating systems offer a 'switch user' capability allowing users to authenticate with their individual credentials and, when needed, 'switch' to the administrator role. This method provides for unique individual authentication prior to using a group authenticator. Some applications may not have the need to provide a group authenticator; this is considered a matter of application design. In those instances where the application design includes the use of a group authenticator, this requirement will apply. There may also be instances when specific user actions need to be performed on the information system without unique user identification or authentication. An example of this type of access is a web server which contains publicly releasable information. These types of accesses are allowed but must be explicitly identified and documented by the organization. When group accounts are utilized without another means of identifying individual users, users may deny having performed a particular action.

Checks: C-41670r667549_chk

Review DBMS settings, OS settings, and/or enterprise-level authentication/access mechanism settings to determine whether group accounts exist. If group accounts do not exist, this is NA. Review DBMS settings to determine if individual authentication is required before group authentication. If group authentication does not require prior individual authentication, this is a finding. (Oracle Access Manager may be helpful in meeting this requirement. Notes on Oracle Access Manager follow.) Oracle Access Manager is used when there is a need for multifactor authentication of applications front-ending Oracle Datasets that may use group accounts. Oracle Access Manager supports using PKI-based smart cards (CAC, PIV) for multifactor authentication. When a user authenticates to a smart card application, the smart card engine produces a certificate-based authentication token. You can configure a certificate-based authentication scheme in Oracle Access Manager that uses information from the smart card certificate. Certificate-based authentication works with any smart card or similar device that presents an X.509 certificate. Check: First, check that the Authentication Module is set up properly: 1) Go to Oracle Access Manager Home Screen and click the Policy Configuration tab. Select the X509Scheme. 2) Make sure the Authentication Module option is set to X509Plugin. Second, check your Authentication policy is using the x509Scheme: 1) Go to Oracle Access Manager Home Screen and click the Policy Configuration tab. 2) Select Application Domains. Select Search. 3) Select the application domain protecting the Oracle Database. 4) Select the Authentication Polices tab and Click Protected Resource Policy. 5) Make sure the Authentication Scheme is set to x509Scheme.

Attackers that are able to exploit an inactive DBMS account can potentially obtain and maintain undetected access to the database. Owners of inactive DBMS accounts will not notice if unauthorized access to their user account has been obtained. All DBMS need to track periods of user inactivity and disable accounts after 35 days of inactivity. Such a process greatly reduces the risk that accounts will be hijacked, leading to a data compromise. To address access requirements, some database administrators choose to integrate their databases with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements. Such integration allows the database administrator to off-load those access control functions and focus on core application features and functionality. This policy does not apply to either emergency accounts or infrequently used accounts. Infrequently used accounts are local logon administrator accounts used by system administrators when network or normal logon/access is not available. Emergency accounts are administrator accounts created in response to crisis situations. Note that user authentication and account management must be done via an enterprise-wide mechanism whenever possible.

If all user accounts are managed and authenticated by the OS or an enterprise-level authentication/access mechanism, and not by Oracle, this is not a finding. For accounts managed by Oracle, check DBMS settings to determine if accounts can be automatically disabled by the system after 35 days of inactivity. Also, ask the DBA if an alternative method, such as a stored procedure run daily, to disable Oracle-managed accounts inactive for more than 35 days, has been deployed. If the ability to disable accounts after 35 days of inactivity, by either of these means, does not exist, this is a finding.

For accounts managed by Oracle, create a script or store procedure that runs once a day. Write a SQL statement to determine accounts that have not logged in within 35 days: Example: select username from dba_audit_trail where action_name = 'LOGON' group by username having max(timestamp) < sysdate - 36 And then disable all accounts that have not logged in within 35 days.

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements. Weak passwords are a primary target for attack to gain unauthorized access to databases and other systems. Where username/password is used for identification and authentication to the database, requiring the use of strong passwords can help prevent simple and more sophisticated methods for guessing at passwords. Note that user authentication and account management must be done via an enterprise-wide mechanism whenever possible.

Password complexity or strength is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor of several that determine how long it takes to crack a password. The more complex the password is, the greater the number of possible combinations that need to be tested before the password is compromised. Use of a complex password helps to increase the time and resources required to compromise the password.

Passwords need to be changed at specific policy-based intervals. If the information system or application allows the user to consecutively reuse extensive portions of their password when they change their password, the end result is a password that has not had enough elements changed to meet the policy requirements. Changing passwords frequently can thwart password-guessing attempts or re-establish protection of a compromised DBMS account. Minor changes to passwords may not accomplish this since password guessing may be able to continue to build on previous guesses, or the new password may be easily guessed using the old password. Note that user authentication and account management must be done via an enterprise-wide mechanism whenever possible.

Password maximum lifetime is the maximum period of time, (typically in days) a user's password may be in effect before the user is forced to change it. Passwords need to be changed at specific policy-based intervals as per policy. Any password, no matter how complex, can eventually be cracked. One method of minimizing this risk is to use complex passwords and periodically change them. If the application does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the system and/or application passwords could be compromised. New accounts authenticated by passwords that are created without a password or with an easily guessed password are vulnerable to unauthorized access. Procedures for creating new accounts with passwords should include the required assignment of a temporary password to be modified by the user upon first use.

Password maximum lifetime is the maximum period of time, (typically in days) a user's password may be in effect before the user is forced to change it. Passwords need to be changed at specific policy-based intervals as per policy. Any password, no matter how complex, can eventually be cracked. One method of minimizing this risk is to use complex passwords and periodically change them. If the application does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the system and/or application passwords could be compromised. The storage of passwords in application source or batch job code that is compiled, encoded, or encrypted prevents compliance with password expiration and other management requirements, as well as provides another means for potential discovery. This requirement applies equally to those accounts managed by Oracle and those managed and authenticated by the OS or an enterprise-wide mechanism. This requirement should not be construed as prohibiting or discouraging the encryption of source code, which remains an advisable precaution. This calls for inspection of application source code, which will require collaboration with the application developers. It is recognized that in many cases, the database administrator (DBA) is organizationally separate from the application developers and may have limited, if any, access to source code. Nevertheless, protections of this type are so important to the secure operation of databases that they must not be ignored. At a minimum, the DBA must attempt to obtain assurances from the development organization that this issue has been addressed and must document what has been discovered.

Checks: C-41680r667579_chk

Review application source code required to be encoded or encrypted for database accounts used by applications or batch jobs to access the database. Review source batch job code prior to compiling, encoding, or encrypting for database accounts used by applications or the batch jobs themselves to access the database. Determine if the compiled, encoded, or encrypted application source code or batch jobs contain passwords used for authentication to the database. If any of the identified compiled, encoded, or encrypted application source code or batch job code do contain passwords used for authentication to the database, this is a finding. The check would depend on the information provided by the DBA. In a default Oracle installation, all passwords are stored in an encrypted manner. Ask the DBA if they have created an External Password Store for applications, batch jobs, and scripts to use. Secure External Password Store: You can store password credentials for connecting to databases by using a client-side Oracle wallet. An Oracle wallet is a secure software container that stores authentication and signing credentials. This wallet usage can simplify large-scale deployments that rely on password credentials for connecting to databases. When this feature is configured, application code, batch jobs, and scripts no longer need embedded user names and passwords. This reduces risk because the passwords are no longer exposed, and password management policies are more easily enforced without changing application code whenever user names or passwords change. The external password store of the wallet is separate from the area where public key infrastructure (PKI) credentials are stored. Consequently, you cannot use Oracle Wallet Manager to manage credentials in the external password store of the wallet. Instead, use the command-line utility mkstore to manage these credentials. How Does the External Password Store Work? Typically, users (and as applications, batch jobs, and scripts) connect to databases by using a standard CONNECT statement that specifies a database connection string. This string can include a user name and password, and an Oracle Net service name identifying the database on an Oracle Database network. If the password is omitted, the connection prompts the user for the password. For example, the service name could be the URL that identifies that database, or a TNS alias you entered in the tnsnames.ora file in the database. Another possibility is a host:port:sid string. The following examples are standard CONNECT statements that could be used for a client that is not configured to use the external password store: CONNECT salesapp@sales_db.us.example.com Enter password: password CONNECT salesapp@orasales Enter password: password CONNECT salesapp@ourhost37:1527:DB17 Enter password: password In these examples, salesapp is the user name, with the unique connection string for the database shown as specified in three different ways. You could use its URL sales_db.us.example.com, or its TNS alias, orasales, from the tnsnames.ora file, or its host:port:sid string. However, when clients are configured to use the secure external password store, applications can connect to a database with the following CONNECT statement syntax, without specifying database logon credentials: CONNECT /@db_connect_string CONNECT /@db_connect_string AS SYSDBA CONNECT /@db_connect_string AS SYSOPER In this specification, db_connect_string is a valid connection string to access the intended database, such as the service name, URL, or alias as shown in the earlier examples. Each user account must have its own unique connection string; you cannot create one connection string for multiple users. In this case, the database credentials, user name and password, are securely stored in an Oracle wallet created for this purpose. The autologin feature of this wallet is turned on, so the system does not need a password to open the wallet. From the wallet, it gets the credentials to access the database for the user they represent.

Fix: F-41639r667580_fix

Design DBMS application code and batch job code that is compiled, encoded or encrypted, to NOT contain passwords. Oracle provides the capability to provide for a secure external password facility. Use the Oracle mkstore to create a secure storage area for passwords for applications, batch jobs, and scripts to use or deploy a site-authorized facility to perform this function. Check to see what has been stored in the Oracle External Password Store. To view all contents of a client wallet external password store, check specific credentials by viewing them. Listing the external password store contents provides information you can use to decide whether to add or delete credentials from the store. To list the contents of the external password store, enter the following command at the command line: $ mkstore -wrl wallet_location -listCredential For example: $ mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -listCredential The wallet_location specifies the path to the directory where the wallet, whose external password store contents you want to view, is located. This command lists all of the credential database service names (aliases) and the corresponding user name (schema) for that database. Passwords are not listed. Configuring Clients to use the External Password Store: If your client is already configured to use external authentication, such as Windows native authentication or Transport Layer Security (TLS), then Oracle Database uses that authentication method. The same credentials used for this type of authentication are typically also used to log in to the database. For clients not using such authentication methods or wanting to override them for database authentication, you can set the SQLNET.WALLET_OVERRIDE parameter in sqlnet.ora to TRUE. The default value for SQLNET.WALLET_OVERRIDE is FALSE, allowing standard use of authentication credentials as before. If you want a client to use the secure external password store feature, then perform the following configuration task: 1. Create a wallet on the client by using the following syntax at the command line: mkstore -wrl wallet_location -create For example: mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -create Enter password: password The wallet_location is the path to the directory where you want to create and store the wallet. This command creates an Oracle wallet with the autologin feature enabled at the location you specify. The autologin feature enables the client to access the wallet contents without supplying a password. The mkstore utility -create option uses password complexity verification. 2. Create database connection credentials in the wallet by using the following syntax at the command line: mkstore -wrl wallet_location -createCredential db_connect_string username Enter password: password For example: mkstore -wrl c:\oracle\product\11.2.0\db_1\wallets -createCredential oracle system Enter password: password In this specification: The wallet_location is the path to the directory where you created the wallet. The db_connect_string used in the CONNECT /@db_connect_string statement must be identical to the db_connect_string specified in the -createCredential command. The db_connect_string is the TNS alias you use to specify the database in the tnsnames.ora file or any service name you use to identify the database on an Oracle network. By default, tnsnames.ora is located in the $ORACLE_HOME/network/admin directory on UNIX systems and in ORACLE_HOME\network\admin on Windows. The username is the database logon credential. When prompted, enter the password for this user. 3. In the client sqlnet.ora file, enter the WALLET_LOCATION parameter and set it to the directory location of the wallet you created in Step 1. For example, if you created the wallet in $ORACLE_HOME/network/admin and your Oracle home is set to /private/ora11, then you need to enter the following into your client sqlnet.ora file: WALLET_LOCATION = (SOURCE = (METHOD = FILE) (METHOD_DATA = (DIRECTORY = /private/ora11/network/admin) ) ) 4. In the client sqlnet.ora file, enter the SQLNET.WALLET_OVERRIDE parameter and set it to TRUE as follows: SQLNET.WALLET_OVERRIDE = TRUE This setting causes all CONNECT /@db_connect_string statements to use the information in the wallet at the specified location to authenticate to databases. When external authentication is in use, an authenticated user with such a wallet can use the CONNECT /@db_connect_string syntax to access the previously specified databases without providing a user name and password. However, if a user fails that external authentication, then these connect statements also fail. Below is a sample sqlnet.ora file with the WALLET_LOCATION and the SQLNET.WALLET_OVERRIDE parameters set as described in Steps 3 and 4. WALLET_LOCATION = (SOURCE = (METHOD = FILE) (METHOD_DATA = (DIRECTORY = /private/ora12/network/admin) ) ) SQLNET.WALLET_OVERRIDE = TRUE SSL_CLIENT_AUTHENTICATION = FALSE SSL_VERSION = 1.2 (Note: This assumes that a single sqlnet.ora file, in the default location, is in use. Please see the supplemental file "Non-default sqlnet.ora configurations.pdf" for how to find multiple and/or differently located sqlnet.ora files.)

Password maximum lifetime is the maximum period of time, (typically in days) a user's password may be in effect before the user is forced to change it. Passwords need to be changed at specific policy-based intervals as per policy. Any password, no matter how complex, can eventually be cracked. One method of minimizing this risk is to use complex passwords and periodically change them. If the application does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the system and/or application passwords could be compromised. The PASSWORD_LIFE_TIME parameter defines the number of days a password remains valid. This can, but must not be, set to UNLIMITED. Further, the PASSWORD_GRACE_TIME parameter, if set to UNLIMITED, can nullify the PASSWORD_LIFE_TIME. PASSWORD_GRACE_TIME must be set to 0 days (or another small integer). Note that user authentication and account management must be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP. With respect to Oracle, this requirement applies to cases where it is necessary to have accounts directly managed by Oracle.

If all user accounts are authenticated by the OS or an enterprise-level authentication/access mechanism, and not by Oracle, this is not a finding. Review DBMS settings to determine if passwords must be changed periodically. If not, this is a finding: SELECT p1.profile, CASE p1.limit WHEN 'UNLIMITED' THEN 'UNLIMITED' ELSE CASE p2.limit WHEN 'UNLIMITED' THEN 'UNLIMITED' ELSE CASE p3.limit WHEN 'UNLIMITED' THEN 'UNLIMITED' ELSE CASE p4.limit WHEN 'UNLIMITED' THEN 'UNLIMITED' ELSE TO_CHAR(DECODE(p1.limit, 'DEFAULT', p3.limit, p1.limit) + DECODE(p2.limit, 'DEFAULT', p4.limit, p2.limit)) END END END END effective_life_time FROM dba_profiles p1, dba_profiles p2, dba_profiles p3, dba_profiles p4 WHERE p1.profile=p2.profile AND p3.profile='DEFAULT' AND p4.profile='DEFAULT' AND p1.resource_name='PASSWORD_LIFE_TIME' AND p2.resource_name='PASSWORD_GRACE_TIME' AND p3.resource_name='PASSWORD_LIFE_TIME' -- from DEFAULT profile AND p4.resource_name='PASSWORD_GRACE_TIME' -- from DEFAULT profile order by 1; If the "effective_life_time" is greater than 60 for any profile applied to user accounts, and the need for this has not been documented and approved by the ISSO, this is a finding. If the value is greater than 35 for any profile applied to user accounts, and the DBMS is configured to use Password Lifetime to disable inactive accounts (see requirement SRG-APP-000025-DB-000004), this is a finding.

Fix: F-41640r708143_fix

For user accounts managed by Oracle: Modify DBMS settings to force users to periodically change their passwords. For example, using PPPPPP to stand for a profile name: ALTER PROFILE PPPPPP LIMIT PASSWORD_LIFE_TIME 35 PASSWORD_GRACE_TIME 0; Do this for each profile applied to user accounts. (Note that although the DoD requirement is for a password change every 60 days, using a value of â€œ35â€? facilitates the use of PASSWORD_LIFE_TIME as a means of locking accounts inactive for 35 days, as required by SRG-APP-000025-DB-000004. But if 35 is not a practical or acceptable limit for password lifetime, set it to the standard DoD value of 60, and use another method to satisfy SRG-APP-000025-DB-000004.) Where a password lifetime longer than 60 is needed, document the reasons and obtain ISSO approval.

The DBMS must employ cryptographic mechanisms to protect the integrity and confidentiality of non-local maintenance and diagnostic communications.

The act of managing systems and applications includes the ability to access sensitive application information, such as system configuration details, diagnostic information, user information, and potentially sensitive application data. When applications provide a remote management capability inherent to the application, the application needs to ensure all sessions and network connections are terminated when non-local maintenance is completed. When network connections are left open after the database session has closed, the network session is open to session hijacking. The Oracle Listener inherently meets most of this SRG requirement. When a user logs off, or times out, or encounters an unrecoverable network fault, the Oracle Listener terminates all sessions and network connections. The remaining aspect of the requirement, the timeout because of inactivity, is configurable.

Checks: C-41684r667591_chk

Review DBMS settings, OS settings, and vendor documentation to verify network connections are terminated when a database communications session is ended or after a DoD-defined period of inactivity.

Use of cryptography to provide confidentiality and non-repudiation is not effective unless strong methods are employed. Many earlier encryption methods and modules have been broken and/or overtaken by increasing computing power. The NIST FIPS 140-2 cryptographic standards provide proven methods and strengths to employ cryptography effectively. Detailed information on the NIST Cryptographic Module Validation Program (CMVP) is available at http://csrc.nist.gov/groups/STM/cmvp/index.html. Note: this does not require that all databases be encrypted. It specifies that if encryption is required, then the implementation of the encryption must satisfy the prevailing standards.

Cryptography is only as strong as the encryption modules/algorithms employed to encrypt the data. Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. Data files that are not encrypted are vulnerable to theft. When data files are not encrypted they can be copied and opened on a separate system. The data can be compromised without the information owner's knowledge that the theft has even taken place.

Emergency application accounts are typically created due to an unforeseen operational event or could ostensibly be used in the event of a vendor support visit where a support representative requires a temporary unique account in order to perform diagnostic testing or conduct some other support-related activity. When these types of accounts are created, there is a risk that the temporary account may remain in place and active after the support representative has left. In the event emergency application accounts are required, the application must ensure accounts that are designated as temporary in nature shall automatically terminate these accounts after an organization-defined time period. Such a process and capability greatly reduces the risk that accounts will be misused, hijacked, or application data compromised. Note: User authentication and account management must be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP. This requirement applies to cases where it is necessary to have accounts directly managed by Oracle. If it is possible for any temporary emergency accounts to be created and managed by Oracle, then the DBMS or application must provide or utilize a mechanism to automatically terminate such accounts after an organization-defined time period. Emergency database accounts must be automatically terminated after an organization-defined time period in order to mitigate the risk of the account being misused.

Checks: C-41687r667600_chk

If the organization has a policy, consistently enforced, forbidding the creation of emergency or temporary accounts, this is not a finding.

A variety of technologies exist to limit, or in some cases, eliminate the effects of DoS attacks. For example, boundary protection devices can filter certain types of packets to protect devices on an organization's internal network from being directly affected by DoS attacks. Employing increased capacity and bandwidth combined with service redundancy may reduce the susceptibility to some DoS attacks. Some of the ways databases can limit their exposure to DoS attacks are through limiting the number of connections that can be opened by a single user and database clustering.

Organizations are required to employ integrity verification applications on information systems to look for evidence of information tampering, errors, and omissions. The organization is also required to employ good software engineering practices with regard to commercial off-the-shelf integrity mechanisms (e.g., parity checks, cyclical redundancy checks, and cryptographic hashes), and to use tools to automatically monitor the integrity of the information system and the applications it hosts. The DBMS opens data files and reads configuration files at system startup, system shutdown, and during abort recovery efforts. If the DBMS does not verify the trustworthiness of these files, it is vulnerable to malicious alterations of its configuration or unauthorized replacement of data.

Checks: C-41689r667606_chk

Verify the DBMS system initialization and shutdowns are configured to ensure the DBMS system and data files remain in a secure state. If the DBMS does not support this, verify third-party software or custom scripting at the OS level performs this function.

System availability is a key tenet of system security. Organizations need to have the flexibility to be able to define the automated actions taken in response to an identified incident. This includes being able to define a least disruptive action the application takes to terminate suspicious events. A least disruptive action may include initiating a request for human response rather than blocking traffic or disrupting system operation. In order to preserve availability, it is important for the DBMS to terminate suspicious events with the least disruptive action possible. If suspicious events are not terminated, an attacker may gain entry into the system; however, if the system overreacts to a suspicious event and takes an overly disruptive action, a Denial of Service (DoS) may occur.

Checks: C-41690r667609_chk

Obtain the CC/S/A/FA's list of suspicious event types and the actions to be taken in response, ordered from least disruptive to last resort. If the list does not exist, this is a finding. For each event type in the list, review the measures in place in the DBMS/database configuration that are designed to detect and/or counter the event. (Alerting an administrator or operator to the problem is a valid measure.) If, for any event type defined in the list, no means of detecting the event exists, this is a finding. For each event type where an automatic countermeasure is defined, verify that its implementation is congruent with the list of defined actions. If not, this is a finding. Verify that administrators/operators are familiar with the list and the notification mechanism and are equipped to follow the instructions in the list. If not, this is a finding.

Fix: F-41649r667610_fix

If the list does not exist, create it. For any event type defined in the list where no means of detecting the event exists, either create the means of detection or modify the list. For each event type where an automatic countermeasure is defined but its implementation differs from its description in the list, either modify the countermeasure or amend the list. If any administrators/operators are unfamiliar with the list or the notification mechanism, train them. If any administrators/operators are not equipped to follow the instructions in the list, provide them with the means to do so. Ensure the list is incorporated into, or referenced by, the System Security Plan. Note that Oracle Audit Vault and Oracle Database Vault are optional products that can be of considerable use in implementing active protection measures of this kind.

This requirement is intended to limit exposure due to operating from within a privileged account or role. The inclusion of role is intended to address those situations where an access control policy, such as Role Based Access Control (RBAC), is being implemented and where a change of role provides the same degree of assurance in the change of access authorizations for both the user and all processes acting on behalf of the user as would be provided by a change between a privileged and non-privileged account. To limit exposure when operating from within a privileged account or role, the application must support organizational requirements that users of information system accounts, or roles, with access to organization-defined lists of security functions or security-relevant information, use non-privileged accounts, or roles, when accessing other (non-security) system functions. Use of privileged accounts for non-administrative purposes puts data at risk of unintended or unauthorized loss, modification, or exposure. In particular, DBA accounts if used for non-administration application development or application maintenance can lead to miss-assignment of privileges where privileges are inherited by object owners. It may also lead to loss or compromise of application data where the elevated privileges bypass controls designed in and provided by applications. The DBMS software installation account may require privileges not required for database administration or other functions. Use of accounts configured with excess privileges may result in the loss or compromise of data or system settings due to elevated privileges that bypass controls designed to protect them.
