Predictable failure prevention requires organizational planning to address system failure issues. If components key to maintaining system security fail to function, then SQL Server could continue operating in an unsecure state. The organization must be prepared, and the system must be configured, to send an alarm for such conditions and/or automatically shut SQL Server down. If appropriate actions are not taken when component failures occur, a denial of service condition may occur. Appropriate actions can include conducting a graceful application shutdown to avoid losing information. For the purposes of this requirement, "component" may be interpreted as meaning any of the Windows services that comprise a SQL Server instance. "The system" encompasses SQL Server itself, the Windows operating system, and any monitoring/management tools used to control the server.true
Checks: C-47560r6_chk

Check the configuration of SQL Server, the operating system and any monitoring/management tools to verify the system activates an alarm and/or triggers a shutdown of SQL Server when a component failure is detected. If system does not take either or both actions, this is a finding.

Fix: F-46187r4_fix

Configure the system to activate an alarm and/or trigger a SQL Server shutdown when a component failure is detected.

The structure and content of SQL Server error messages need 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. Database logs can be monitored for specific security-related errors. Any error that can have a negative effect on database security should be quickly identified and forwarded to the appropriate personnel. If security-relevant error conditions are not identified by SQL Server they may be overlooked by the personnel responsible for addressing them.
Checks: C-47561r2_chk

Security-related errors must be identified and monitored. In most cases, these items would appear in the SQL Server log file. If security-related error conditions are not being monitored to meet this requirement, this is a finding.

Fix: F-46188r2_fix

Monitor SQL Server log files to determine when a security-related error occurs. Add/Update list of appropriate personnel that are to be alerted when a security related error condition occurs to system documentation. Consider an automated job for both the monitor and the alerting.

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), VPN, or IPSEC tunnel. 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.true
Checks: C-47562r9_chk

If the DBMS exists in the unclassified environment, and data transmission does not cross the boundary between the NIPRNet and the wider Internet, and the application owner and authorizing official have determined that encryption is not required, this is not a finding. Check SQL Server and network settings to determine whether cryptographic mechanisms are used to prevent the unauthorized disclosure of information during transmission. If not, this is a finding. Review system documentation to determine whether the system handles classified information. If the system does not handle classified information, the severity of this check should be downgraded to Category II. From Command Prompt, open SQL Server Configuration Manager by typing sqlservermanager11.msc, and pressing [ENTER]. Navigate to SQL Server Configuration Manager >> SQL Server Network Configuration. Right click on Protocols for [NAME OF INSTANCE], where [NAME OF INSTANCE] is a placeholder for the SQL Server instance name, and click on Properties. On the Flags tab, if Force Encryption is set to "YES", examine the certificate used on the Certificate tab. If Force Encryption is set, a DoD Certificate is not utilized, and a physical encryption measure is utilized, examine the physical encryption devices to determine the following: 1. The plaintext connection to the database server is afforded the highest protections, allowing no access to unauthorized or non-cleared personnel. 2. The encryption device is configured to pass traffic to only the specific IP addresses as identified by the database documentation. 3. The encryption keys utilized are current and valid keys. 4. The keys utilized meet approved organizationally defined compliant algorithms. If any of the preceding requirements is not met, this is a finding. If Force Encryption is set to "NO" or a DoD Certificate is not utilized, and physical encryption measures are not utilized, this is a finding.

Fix: F-46189r4_fix

Deploy organization-approved encryption to the SQL Server network connections. Where physical network devices are used for encryption, set them up such that: 1. The plaintext connection to the database server is afforded the highest protections, allowing no access to unauthorized or non-cleared personnel. 2. The encryption device is configured to pass traffic to only the specific IP addresses as identified by the database documentation. 3. The encryption keys utilized are current and valid keys. 4. The keys utilized meet approved organizationally defined compliant algorithms. Where SQL Server network encryption is used, open SQL Server Configuration Manager. Navigate to SQL Server Configuration Manager >> SQL Server Network Configuration. Right click on Protocols for [NAME OF INSTANCE], where [NAME OF INSTANCE] is a placeholder for the SQL Server instance name, and click on Properties. On the Flags tab, set Force Encryption to YES, provide a DoD certificate on the Certificate tab.

b
SQL Server must ensure, if Database Availability Groups are being used and there is a server failure, that none of the potential failover servers would suffer from resource exhaustion.

SQL Server has a feature called 'Availability Group' which provides automatic failover from a primary SQL Server to a secondary server. This concept is not new, but because SQL Server does warn that if the secondary SQL Server is not dedicated 100% to being a backup server, that "resource exhaustion" may be an issue if there is some load balancing going on. If the primary SQL Server has a backup/secondary server that is dedicated 100% to the primary server's process, this is not a finding. If, however, the processing of the primary SQL Server is loaded to a secondary server that is already partly resourced to process something other than that of the primary SQL Server responsibility, then there can be load balancing issues. Load balancing for the purpose of sharing a secondary/backup SQL Server is often done to share and save on resources.
Checks: C-47563r3_chk

If Database Availability Groups are not being used, this is not applicable (NA). Check the system documentation and check with the administrator regarding processing resources of the backup/secondary SQL Server. If the primary SQL Server has a backup/secondary server that is dedicated 100% to the primary server's processing, this is not a finding. If the secondary/backup SQL Server is already partly resourced to process something other than that of the primary SQL Server processing, then determine what resources would be required for the secondary/backup SQL Server. If the secondary/backup SQL Server is determined to not have enough processing resources to fulfill the function of the primary server's SQL Server process, this is a finding.

Fix: F-46190r3_fix

Allocate replacement server(s) to provide failover support to the Primary SQL Server. If a single solution cannot be employed, split the processing of a secondary SQL Server amongst two or more secondary servers.

Priority protection helps prevent a lower-priority process from delaying or interfering with the information system servicing any higher-priority process. This control does not apply to components in the information system for which there is only a single user/role. The application must limit the use of resources by priority. SQL Server often runs queries for multiple users at the same time. If lower priority processes are utilizing a disproportionately high amount of database resources, this can severely impact higher priority processes. Even if SQL Server's utilization is very small and there may seem to be no need to priority protection, often resources grow exponentially and must be implemented as part of an initial deployment.
Checks: C-47564r2_chk

Review system documentation and determine if one type or more of SQL Server users has a business need for priority usage over other types of users. The need for prioritization most frequently occurs when SQL Server resources are shared between two or more applications or systems where the number of users on more than one system is small or non-existent. This needs to be the case, because SQL Server limits resource based on user accounts and not what process is running. If SQL Server has users that are determined to run significantly high priority processes than other users and the SQL Server "Resource Governor" is not being implemented, this is a finding.

Fix: F-46191r2_fix

SQL Server utilizes the "Resource Governor" to determine who is allowed high processing resources. There are several configurations regarding the "Resource Governor" that mostly comes down to users or groups of users having a "MAX_CPU_PERCENT", "MIN_CPU_PERCENT", "MIN_MEMORY_PERCENT", and/or "MAX_MEMORY_PERCENT" settings. Users are assigned to Workgroups and the Workgroups are configured processing resources via the "Resource Governor".

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 nonsecurity functionality via separate databases or schemas. Database objects or code implementing security functionality should not be commingled with objects or code implementing application logic. When security and nonsecurity functionality is commingled, users who have access to nonsecurity functionality may be able to access security functionality.true
Checks: C-47565r3_chk

Determine elements of security functionality (lists of permissions, additional authentication information, stored procedures, application specific auditing, etc.) which are being housed inside SQL server. For any elements found, check SQL Server to determine if these objects or code implementing security functionality are located in a separate security domain, such as a separate database or schema created specifically for security functionality. Run the following queryto list all the user-defined databases: SELECT Name FROM sys.databases WHERE database_id > 4 ORDER BY 1; If security-related database objects or code are not kept separate, this is a finding.

Fix: F-46192r1_fix

Locate security-related database objects and code in a separate database, schema, or other separate security domain from database objects and code implementing application logic.

When data is exchanged between information systems, the security attributes associated with said data need to be maintained. Security attributes are an abstraction representing the basic properties or characteristics of an entity with respect to safeguarding information, typically associated with internal data structures (e.g., records, buffers, files) within the information system and used to enable the implementation of access control and flow control policies, reflect special dissemination, handling or distribution instructions, or support other aspects of the information security policy. Security attributes may be explicitly or implicitly associated with the information contained within the information system. If database security labels are not maintained as information moves between systems, handling instructions can be lost and data can be accidentally distributed to unauthorized individuals.
Checks: C-47567r2_chk

Review system documentation to determine if the labeling of sensitive data is required under organization-defined guidelines. If the labeling of sensitive data is not required, this is NA. Obtain system configuration setting to determine how data labeling is being performed. This can be through triggers or some other SQL developed means or via a third-party tool. Check to ensure that labels are being associated to data when information is being exchanged between systems. If the labeling is not being associated to data when exchanging data between systems, this is a finding.

Fix: F-46194r3_fix

Develop SQL code or acquire a third party tool to perform data labeling. SQL Server Label Security Toolkit can be downloaded from http://www.codeplex.com. This tool can satisfy all data labeling and security data labeling requirements.

If SQL Server contains publicly available information, though not concerned with confidentiality, SQL Server must maintain the integrity of the data. If data available to the public is not protected from unauthorized modification or deletion, then the data cannot be trusted by those accessing it. The user account associated with public access must not have access to the OS or SQL Server configuration information, include read access to schema information. This requirement is not intended to prevent the establishment of public-facing systems for the purpose of collecting data from the public.
Checks: C-47568r2_chk

If SQL Server is not housing or distributing publicly available information, this finding is NA. Obtain from the DBA or system documentation the list of publicly available data within SQL Server and the role names that assign read-only access to that public data. Obtain the publicly available user account name being used to access SQL Server. Navigate to Start >> Administrative Tools >> Server Manager >> Server Manager (<'server name'>) >> Configuration >> Local Users and Groups >> Groups >> right click 'Guests' >> Properties >> 'Members:' The publicly available user account will likely be in the OS 'Guests' group.

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. NSA has developed Type 1 algorithms for protecting classified information. The Committee on National Security Systems (CNSS) National Information Assurance Glossary (CNSS Instruction No. 4009) defines Type 1 products as: “Cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed. Developed using established NSA business processes and containing NSA approved algorithms are used to protect systems requiring the most stringent protection mechanisms.” NSA-approved cryptography is required to be used for classified information system processing. See FIPS Publication 140-2 and related documents for guidance on approved encryption techniques and certified encryption modules.true

Review system documentation to determine whether cryptography for classified or sensitive information is required by the information owner. If the system documentation does not specify the type of information hosted on SQL Server: classified, sensitive and/or unclassified, this is a finding. If neither classified nor sensitive information exists within SQL Server databases or configuration, this requirement is NA. Note: If the SQL Server is compliant, nothing is displayed. If cryptography is being used by SQL Server, examine evidence that an audit record is created whenever the asymmetric key is accessed by other than authorized users. In particular, view evidence that access by a SYSADMIN or other system privileged account results in the generation of an audit record. This is required because system privileges allow access to encryption keys and can be used to access sensitive data where there is not a need-to-know. Note: The list of acceptable algorithms: "AES 128", "AES 192", "AES 256" and "Triple DES". If cryptography is being used by SQL Server, verify that the cryptography is NIST FIPS 140-2 certified by running the following SQL query: EXEC sp_MSforeachdb ' DECLARE @nCount integer; SELECT @nCount = Count(*) FROM [?].sys.symmetric_keys WHERE key_algorithm NOT IN (''D3'',''A1'',''A2'',''A3''); IF @nCount &gt; 0 SELECT ''?''

Fix: F-46200r9_fix

Document within the system documentation the type of information hosted on SQL Server: classified, sensitive, and/or unclassified. Obtain and utilize native or third-party NIST-validated FIPS 140-2 compliant cryptography solution on SQL Server. Configure cryptographic functions to use FIPS 140-2 compliant algorithms functions. Use DoD certificates to create asymmetric keys stored in the database and used to encrypt sensitive data stored in the database. Run the following SQL script to create a certificate: USE <database name> CREATE CERTIFICATE <certificate name> ENCRYPTION BY PASSWORD = '<password>' FROM FILE = '<path/file_name>' WITH SUBJECT = '<name of person creating key>', EXPIRY_DATE = '<expiration date: yyyymmdd>' Run the following SQL script to create a symmetric key and assign an existing certificate: USE <database name> CREATE SYMMETRIC KEY <'key name'> WITH ALGORITHM = AES_256 ENCRYPTION BY CERTIFICATE <certificate name> Assign the application object owner account as the owner of asymmetric and symmetric keys, and certificates. (Ownership is assigned via the AUTHORIZATION clause of the CREATE statement, or the ALTER AUTHORIZATION statement.) Create audit events for access to the key by other than the application owner account or approved application objects. (If using a server-level SQL Server Audit specification, DATABASE_OBJECT_PERMISSION_CHANGE_GROUP accomplishes this.) Revoke any privileges on encryption keys assigned to principals other than the application object owner account and authorized users. Protect the private key by encrypting it with the database or service master key. For whole-database encryption (Transparent Data Encryption - TDE): USE master; CREATE MASTER KEY ENCRYPTION BY PASSWORD = '<password>'; CREATE CERTIFICATE <certificate name> . . .; USE <database name>; CREATE DATABASE ENCRYPTION KEY WITH ALGORITHM = AES_256 ENCRYPTION BY SERVER CERTIFICATE <certificate name>; ALTER DATABASE <database name> SET ENCRYPTION ON;

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. This may be accomplished by a code embedded within the userid, or via a flag or code columns in a table of users, or by some other means. In any case, the user must be individually identified to, and within, SQL Server via a mapping to an individual account and not mapping to a shared account. 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, and other organizations.
Checks: C-47574r4_chk

Review documentation, SQL Server settings and authentication system settings to determine if non-organizational users are individually identified and authenticated when logging onto the system. If non-organizational users are not uniquely identified and authenticated, this is a finding.

SQL Server 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. Passwords stored in clear text are vulnerable to unauthorized disclosure. Database passwords should always be encoded or encrypted when stored internally or externally to SQL Server.
Checks: C-47577r2_chk

Since Windows security is being leveraged, this check applies to database configuration files, associated scripts, and applications external to SQL Server that access the database. Ask the DBA and/or IAO to determine if any SQL Server database objects, database configuration files, associated scripts, or applications defined as external to SQL Server that access the database/user environment files/settings contain database passwords. If any do, confirm that SQL Server passwords stored externally to the SQL Server are encoded or encrypted. If any passwords are stored in clear text, this is a finding.

Fix: F-46204r2_fix

To ensure individual accountability and prevent unauthorized access, application users (and any processes acting on behalf of users) must be individually identified and authenticated. A shared authenticator is a generic account used by multiple individuals. Use of a shared authenticator alone does not uniquely identify individual users. An example of a shared authenticator is the UNIX OS 'root' user account, a Windows 'administrator' account, an 'sa' account, or a 'helpdesk' account. Legitimate use of shared accounts includes, for example, connection pooling. Since this is insufficient to ensure non-repudiation, such shared accounts should be kept "under the covers," be inaccessible directly to end users, be invoked only after successful individual authentication, be communicated to the DBMS by the application, and be recorded in all relevant audit contexts. (Shared accounts should not be confused with Windows groups, which are used in role-based access control.)
Checks: C-47578r4_chk

Review SQL Server users to determine whether shared accounts exist. If accounts are determined to be shared, determine if individuals are first individually authenticated. If individuals are not individually authenticated before using the shared account (e.g., by the operating system or possibly by an application making calls to the database), this is a finding. If accounts are determined to be shared, determine if they are directly accessible to end users. If so, this is a finding.

SQL Server backups are a critical step in maintaining data assurance and availability. User-level information is data generated by information system and/or application users. In order to assure availability of this data in the event of a system failure, DoD organizations are required to ensure user generated data is backed up at a defined frequency. This includes data stored on file systems, within databases or within any other storage media. Applications performing backups must be capable of backing up user-level information per the DoD-defined frequency. Lost or compromised SQL Server backup or restoration files may lead to not only the loss of data, but also the unauthorized access to sensitive data. SQL Server can maintain local copies of critical control files to provide transparent or easy recovery from hard disk loss or other interruptions to database operation. Backup files, both local to the SQL Server machine and not local to the machine, need the same protections against unauthorized access when stored on backup media as when online and actively in use by the database system. In addition, the backup media needs to be protected against physical loss.

Application recovery and reconstitution constitutes executing an information system contingency plan comprising activities that restore essential missions and business functions. SQL Server utilizes transaction-based processing and is a good example of information systems that are transaction-based. Transaction rollback and transaction journaling are examples of mechanisms supporting transaction recovery. SQL Server may be vulnerable to use of compromised data or other critical files during recovery. Use of compromised files could introduce maliciously altered application code, relaxed security settings, or loss of data integrity. SQL Server mechanisms must be configured to protect all files that could compromise the system or its data during a SQL Server recovery.
Checks: C-47587r3_chk

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 over limiting the services provided by any one component. 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. For detailed guidance on Ports, Protocols, and Services Management (PPSM), refer to the PPSM section of the Information Assurance Support Environment (IASE) web site, at http://iase.disa.mil/ppsm/Pages/index.aspx.

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 every mission, but which cannot be disabled. Applications must adhere to the principles of least functionality by providing only essential capabilities. DBMSs may spawn additional external processes to execute procedures that are defined in the DBMS, but stored in external host files (external procedures). The spawned process used to execute the external procedure may operate within a different OS security context than the DBMS and provide unauthorized access to the host system. The xp_cmdshell extended stored procedure allows execution of host executables outside the controls of database access permissions. This access may be exploited by malicious users who have compromised the integrity of the SQL Server database process to control the host operating system to perpetrate additional malicious activity.

SQL Server's 'sa' account has special privileges required to administer the database. The 'sa' account is a well-known SQL Server account and is likely to be targeted by attackers and thus more prone to providing unauthorized access to the database. This 'sa' default account is administrative and could lead to catastrophic consequences, including the complete loss of control over SQL Server. If the 'sa' default account is not disabled, an attacker might be able to gain access through the account. SQL Server by default, at installation, disables the 'sa' account. Some applications that run on SQL Server require the 'sa' account to be enabled in order for the application to function properly. These applications that require the 'sa' account to be enabled are usually legacy systems.true

SQL Server is 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 every mission, but which cannot be disabled. Applications must adhere to the principles of least functionality by providing only essential capabilities. Unused and unnecessary SQL Server components increase the number of available attack vectors to SQL Server by introducing additional targets for attack. By minimizing the services and applications installed on the system, the number of potential vulnerabilities is reduced. Components of the system that are unused and cannot be uninstalled must be disabled.
Checks: C-47592r5_chk

Review the components and features included in SQL Server and capable of being disabled (by configuration settings, permissions and privileges, etc.). Take note of those which are enabled. Review the system documentation to verify that the enabled components or features are documented and authorized. If any enabled components or features are not authorized, this is a finding.

Fix: F-46219r2_fix

If any components or features of SQL Server are required for operation of applications that will be accessing SQL Server data or configuration, include them in the system documentation. If any unused components or features of SQL Server are installed and cannot be uninstalled or removed, then disable those components or features.

When dealing with change control issues, it should be noted, any changes to the hardware, software, and/or firmware components of the information system can potentially have significant effects on the overall security of the system. If any user were allowed 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. The DBMS software libraries contain the executables used by the DBMS to operate. Unauthorized access to the libraries can result in compromised installations. This may in turn jeopardize data stored in the DBMS and/or operation of the host system. Accordingly, only qualified and authorized individuals shall be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications. Of particular note in this context is that any software installed for auditing and/or audit file management must be protected and monitored.true

Obtain the SQL Server software directory location: from a command prompt, open the registry editor by typing regedit.exe and pressing [ENTER]. Navigate to the following registry location: HKEY_LOCAL_MACHINE &gt;&gt; SOFTWARE &gt;&gt; Microsoft &gt;&gt; Microsoft SQL Server &gt;&gt; [INSTANCE NAME] &gt;&gt; Setup &gt;&gt; SQLBinRoot In the registry tree, the [INSTANCE NAME] for a SQL Server 2012 database engine instance is normally shown as "MSSQL11" followed by a period and the name that was specified for the SQL Server service at installation time. If multiple SQL Server instances are installed, each will have its own [INSTANCE NAME] node and subtree in the registry. The value in the Data column for the SQLBinRoot registry entry is the file system path for the SQL Server 2012 binaries. Navigate to that folder location using a command prompt or Windows Explorer.

Each virtual account has an equivalent Service SID, with the same name. The installer also creates an equivalent SQL Server login, also with the same name. Applying folder and file permissions to Service SIDs, rather than to domain accounts or local computer accounts, provides tighter control because these permissions are available only to the specific service when it is running and not in any other context.

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. Any time 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. If SQL Server were no longer supported, no patches from Microsoft would address newly discovered security vulnerabilities. Unpatched software is vulnerable to attack.

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 of one application can lead to an exploit of other applications sharing the same security context. For example, an exploit of 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 other applications’ database objects or directories. Any method that provides any level of separation of security context assists in the protection between applications.

Verify the SQL Server installations present on the server. From a Command Prompt, type regedit.exe, and press [ENTER]. Navigate to HKEY_LOCAL_MACHINE &gt;&gt; SOFTWARE &gt;&gt; Microsoft &gt;&gt; Microsoft SQL Server &gt;&gt; Instance Names. Each instance installed on the server possesses a key inside a folder under this registry entry. Analysis Services Instances are registered in the OLAP subfolder. Reporting Services Instances are registered in the RS subfolder. Standard SQL Server Instances are registered in the SQL subfolder. Inside each of these folders, a single key is used to reference an Instance's specific Windows Registry tree. Each key will have its own registry tree at the following registry location: HKEY_LOCAL_MACHINE &gt;&gt; SOFTWARE &gt;&gt; Microsoft &gt;&gt; Microsoft SQL Server &gt;&gt; [INSTANCE NAME]. An [INSTANCE NAME] is listed as the Data component of a key found in one of the above OLAP, RS, or SQL folders. To find the installation location of a particular instance, navigate to the following location in the Windows Registry: HKEY_LOCAL_MACHINE &gt;&gt; SOFTWARE &gt;&gt; Microsoft &gt;&gt; Microsoft SQL Server &gt;&gt; [INSTANCE NAME] &gt;&gt; Setup. Examine the value of the 'SqlProgramDir' key. The value of the 'SqlProgramDir' key is the SQL Server installation directory for that SQL Server Instance. Navigate to that folder location using a Command Prompt or Windows Explorer. Only applications that are required for the functioning and administration, not use, of the SQL Server should be located on the same directory node as the SQL Server software libraries.

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 dependant. However, this requirement does apply to applications with software libraries accessible and configurable, as in the case of interpreted languages. Accordingly, only qualified and authorized individuals shall be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications. DBA and other privileged administrative or application owner accounts are granted privileges that allow actions that can have a greater impact on SQL Server security and operation. It is especially important to grant access to privileged accounts to only those persons who are qualified and authorized to use them.
Checks: C-47602r2_chk

Check system documentation for policy and procedures to restrict use of the SQL Server software installation account. Check OS settings to determine whether users are restricted from accessing SQL Server objects and data they are not authorized to access by checking the local OS user accounts. From a Command Prompt, open lusrmgr.msc. Navigate to Users &gt;&gt; right click individual user &gt;&gt; Properties &gt;&gt; Member Of. If appropriate access controls for all users are not implemented to restrict access to only authorized users and to restrict the access of those users to objects and data they are authorized, this is a finding. Review procedures for controlling and granting access to use of the SQL Server software installation account. If access or use of this account is not restricted to the minimum number of personnel required, or unauthorized access to this account has been granted, this is a finding.

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 potentially have significant effects on the overall security of the system. Only qualified and authorized individuals are allowed to obtain access to information system components for the purposes of initiating changes, upgrades, and modifications. Access restrictions for change also include application software libraries. Examples of access restrictions include: physical and logical access controls, workflow automation, media libraries, abstract layers (i.e., changes are implemented into a third-party interface rather than directly into the information system component), and change windows (i.e., changes occur only during specified times, making unauthorized changes outside the window easy to discover). Multiple applications can provide a cumulative negative effect. A vulnerability and subsequent exploit of one application can lead to an exploit of other applications sharing the same security context. For example, an exploit of 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 other applications’ database objects or directories. Any method that provides any level of separation of security context assists in the protection between applications.

Obtain the SQL Server software library installation directory location. From a command prompt, type regedit.exe, and press [ENTER]. Navigate to HKEY_LOCAL_MACHINE &gt;&gt; SOFTWARE &gt;&gt; Microsoft &gt;&gt; Microsoft SQL Server &gt;&gt; Instance Names. Each instance installed on the server possesses a key inside a folder under this registry entry. Analysis Services Instances are registered in the OLAP subfolder. Reporting Services Instances are registered in the RS subfolder. Standard SQL Server Instances are registered in the SQL subfolder. Inside each one of these folders, a single key is used to reference an instance's specific Windows Registry tree. Each key will have its own registry tree at the following registry location: HKEY_LOCAL_MACHINE &gt;&gt; SOFTWARE &gt;&gt; Microsoft &gt;&gt; Microsoft SQL Server &gt;&gt; [INSTANCE NAME]. An [INSTANCE NAME] is listed as the data component of a key found in one of the above OLAP, RS, or SQL folders. To find the installation location of a particular instance, navigate to the following location in the Windows Registry: HKEY_LOCAL_MACHINE &gt;&gt; SOFTWARE &gt;&gt; Microsoft &gt;&gt; Microsoft SQL Server &gt;&gt; [INSTANCE NAME] &gt;&gt; Setup. Examine the value of the 'SqlProgramDir' key. The value of the 'SqlProgramDir' key is the SQL Server installation directory for that SQL Server Instance. Navigate to that folder location using a command prompt or Windows Explorer. Note any custom subdirectories within the SQL Server software library directory. Only applications that are required for the functioning and administration of SQL Server should be located in the same disk directory as the SQL Server software libraries. If any directories or files not installed with the SQL Server software exist within the SQL Server software library directory, this is a finding.

If audit data were to become compromised, competent forensic analysis and discovery of the true source of potentially malicious system activity would be impossible to achieve. To ensure the veracity of audit data, the information system and/or the application must protect audit information from unauthorized deletion. 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, restricting access, and backing up log data to ensure log data is retained. Applications providing a user interface to audit data will leverage user permissions and roles identifying the user accessing the data and the corresponding rights the user enjoys in order to make decisions regarding the deletion of audit data. Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity. Deletion of database audit data could mask the theft or unauthorized modification of sensitive data stored in the database.true

If audit data were to become compromised, competent forensic analysis and discovery of the true source of potentially malicious system activity would be 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. SQL Server and third-party tools are examples of applications that are easily able to view and manipulate audit file data. Additionally, applications with user interfaces to audit records should not allow unfettered manipulation of, or access to, those records via any application. If an application provides access to the audit data, the application becomes accountable for ensuring that audit information is protected from unauthorized access. This requirement can be achieved through multiple methods, which will depend upon system architecture and design.

Protection of audit records and audit data is of critical importance. Care must be taken to ensure privileged users cannot circumvent audit protections put in place. Auditing might not be reliable when performed by an information system that the user being audited has privileged access to. The privileged user could inhibit auditing or directly modify audit records. To prevent this from occurring, privileged access shall be further defined between audit-related privileges and other privileges, thus limiting the users with audit-related privileges. Reducing the risk of audit compromises by privileged users can also be achieved, for example, by performing audit activity on a separate information system where the user in question has limited access, or by using storage media that cannot be modified (e.g., write-once recording devices). If an attacker were to gain access to audit tools, they could analyze audit logs for system weaknesses or weaknesses in the auditing itself. An attacker could also manipulate logs to hide evidence of malicious activity.true

Obtain the SQL Server audit file location(s) by running the following SQL script: SELECT DISTINCT LEFT(path, (LEN(path) - CHARINDEX('\',REVERSE(path)) + 1)) AS "Audit Path" FROM sys.traces UNION SELECT log_file_path AS "Audit Path" FROM sys.server_file_audits For each audit, the path column will give the location of the file. Verify that all audit files have the correct permissions by doing the following for each audit file: Navigate to audit folder location(s) using a command prompt or Windows Explorer. Right-click the file/folder, click Properties. On the Security tab, verify that at most the following permissions are applied: Administrator(read) Users (none) Audit Administrator (Full Control) Auditors group (Read) SQL Server Service SID OR Service Account (Full Control) [Notes 1, 2] SQL Server SQL Agent Service SID OR Service Account, if SQL Server Agent is in use. (Read, Execute, Write) [Notes 1, 2] If any less restrictive permissions are present (and not specifically justified and approved), this is a finding.

Fix: F-46315r7_fix

Modify audit file permissions to meet the requirement to protect against unauthorized access. Navigate to the audit folder location(s) using a command prompt or Windows Explorer. Right-click on the file, click Properties. On the Security tab, modify the security permissions to: Administrator(read) Users (none) Audit Administrator(Full Control) Auditors group (Read) SQL Server Service SID OR Service Account (Full Control) [Notes 1, 2] SQL Server SQL Agent Service SID OR Service Account, if SQL Server Agent is in use. (Read, Execute, Write) [Notes 1, 2] ----- Note 1: It is highly advisable to use a separate account for each service. When installing SQL Server in single-server mode, you can opt to have these provisioned for you. These automatically-generated accounts are referred to as virtual accounts. Each virtual account has an equivalent Service SID, with the same name. The installer also creates an equivalent SQL Server login, also with the same name. Applying folder and file permissions to Service SIDs, rather than to domain accounts or local computer accounts, provides tighter control, because these permissions are available only to the specific service when it is running, and not in any other context. (However, when using failover clustering, a domain account must be specified at installation, rather than a virtual account.) For more on this topic, see http://msdn.microsoft.com/en-us/library/ms143504(v=sql.110).aspx. Note 2: Tips for adding a service SID/virtual account to a folder's permission list. 1) In Windows Explorer, right-click on the folder and select "Properties." 2) Select the "Security" tab 3) Click "Edit" 4) Click "Add" 5) Click "Locations" 6) Select the computer name 7) Search for the name 7.a) SQL Server Service 7.a.i) Type "NT SERVICE\MSSQL" and click "Check Names".

Information system auditing capability is critical for accurate forensic analysis. Audit record content which may be necessary to satisfy the requirement of this control includes: time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked. Detection of suspicious activity, including access attempts and successful access from unexpected places, during unexpected times, or other unusual indicators, can support decisions to apply countermeasures to deter an attack. Without detection, malicious activity may proceed without hindrance. In SQL Server's case, this is a combination of the standard audit trace, as well as the operating system logs. Only the SQL Server logs are validated for this check, as the other part is dependent upon the operating system.
Checks: C-47638r4_chk

Check to see that all required events are being audited. From the query prompt: SELECT DISTINCT traceid FROM sys.fn_trace_getinfo(0); All currently defined traces for the SQL server instance will be listed. If no traces are returned, this is a finding. Determine the trace(s) being used for the auditing requirement. In the following, replace # with a trace ID being used for the auditing requirements. From the query prompt: SELECT DISTINCT(eventid) FROM sys.fn_trace_geteventinfo(#); The following required event IDs should be listed: 14, 15, 18, 20, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 115, 116, 117, 118, 128, 129, 130, 131, 132, 133, 134, 135, 152, 153, 170, 171, 172, 173, 175, 176, 177, 178. If any of the audit event IDs required above is not listed, this is a finding. Notes: 1. It is acceptable to have the required event IDs spread across multiple traces, provided all of the traces are always active, and the event IDs are grouped in a logical manner. 2. It is acceptable, from an auditing point of view, to include the same event IDs in multiple traces. However, the effect of this redundancy on performance, storage, and the consolidation of audit logs into a central repository, should be taken into account. 3. It is acceptable to trace additional event IDs. This is the minimum list. 4. Once this check is satisfied, the DBA may find it useful to disable or modify the default trace that is set up by the SQL Server installation process. (Note that the Fix does NOT include code to do this.) Use the following query to obtain a list of all event IDs, and their meaning: SELECT * FROM sys.trace_events; 5. Because this check procedure is designed to address multiple requirements/vulnerabilities, it may appear to exceed the needs of some individual requirements. However, it does represent the aggregate of all such requirements. 6. Microsoft has flagged the trace techniques and tools used in this Check and Fix as deprecated. They will be removed at some point after SQL Server 2014. The replacement feature is Extended Events. If Extended Events are in use, and cover all the required audit events listed above, this is not a finding.

It is critical that, when SQL Server is at risk of failing to process audit logs as required, it takes action to mitigate the failure. If the system were to continue processing without auditing enabled, actions could be taken on the system that could not be tracked and recorded for later forensic analysis. In many system configurations, the disk space allocated to the auditing system is separate from the disks allocated for the operating system; therefore, this may not result in a system outage. This places the onus on the DBMS to detect and take actions. A failure of SQL Server auditing will result in either the database continuing to function without auditing, or the halting of SQL Server operations. In this case, the database must cease processing immediately in order to not allow unlogged transaction to occur. Note that trace file rollover does not count as an audit failure, provided that the system is also configured to shut down when it runs out of space. Trace file rollover can be a useful technique for breaking the log into manageable pieces, for archiving, or for transfer to a log management system.true
Checks: C-47639r10_chk

From the query prompt: SELECT DISTINCT traceid FROM sys.fn_trace_getinfo(0); All currently defined traces for the SQL Server instance will be listed. If no traces are returned, this is a finding. Determine the trace being used for the auditing requirement. Replace # in the following code with a traceid being used for the auditing requirements. From the query prompt, determine whether the trace options include the value 4, which means SHUTDOWN_ON_ERROR: SELECT CAST(value AS INT) FROM sys.fn_trace_getinfo(#) where property = 1; If the query does not return a value, this is a finding. If a value is returned but is not 4 or 6, this is a finding. (6 represents the combination of values 2 and 4. 2 means TRACE_FILE_ROLLOVER.) NOTE: Microsoft has flagged the trace techniques and tools used in this STIG as deprecated. They will be removed at some point after SQL Server 2014. The replacement feature is Extended Events. If Extended Events are in use and configured to satisfy this requirement, this is not a finding.

Fix: F-46321r4_fix

If a trace does not exist, create a trace specification that complies with requirements. If a trace exists, but is not set to SHUTDOWN_ON_ERROR, modify the SQL Server audit setting to immediately shutdown the database in the event of an audit failure by setting property 1 to a value of 4 or 6 for the audit. (See the SQL Server Help page for sys.sp_trace_create for implementation details.)

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 will 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 a log repository or the OS when a designated log directory is nearing capacity.

Configure SQL Server during the installation and/or configuration process to determine if adequate storage capacity has been allocated for audit logs. If SQL Server audit logs that are being generated exceed the amount of space reserved for those logs, the system may shutdown or take other measures to stop processing in order to protect transactions from continuing unlogged. After the initial setup of SQL Server audit log configuration, it is best to check the available space frequently until the maximum number of files has been reached. Checking the available space can help determine the balance of online audit data with space required.

Check the SQL Server audit setting on the maximum number of files of the trace used for the auditing requirement. Select * from sys.traces. Determine the audit being used to fulfill the overall auditing requirement. Examine the max_files and max_size parameters. SQL will overwrite the oldest files when the max_files parameter has been exceeded. Care must be taken to ensure that this does not happen, or data will be lost. The amount of space determined for logging by SQL Server is calculated by multiplying the maximum number of files by the maximum file size. If auditing will outgrow the space reserved for logging before being overwritten, this is a finding.

This requires specific information regarding the outcome of the action or event that the audit record is referring to. If outcome status information is not recorded and stored with the audit record, the record itself is of very limited use. Success and failure indicators ascertain the outcome of a particular event. As such, they also provide a means to measure the impact of an event and help authorized personnel to determine the appropriate response. Without knowing the outcome of audit events, it is very difficult to accurately recreate the series of events during forensic analysis. If auditing is enabled, SQL Server does capture the outcome status-specific information in all audit records.

Information system auditing capability is critical for accurate forensic analysis. Audit record content which may be necessary to satisfy the requirement of this control includes, but is not limited to: time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked. SQL Server is capable of a range of actions on data stored within the database. It is important, for accurate forensic analysis, to know exactly who performed what actions. This requires specific information regarding the source of the event an audit record is referring to. If the source of the event information is not recorded and stored with the audit record, the record itself is of very limited use. The source of the event can be a user account and sometimes a system account when timed jobs are run. Without information establishing the source of activity, the value of audit records from a forensics perspective is questionable. If auditing is enabled, SQL Server does capture the source of the event-specific information in all audit records.

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. Use of shared accounts 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 (as in connection pooling). When shared accounts are utilized without another means of identifying individual users, users may deny having performed a particular action. (Shared accounts should not be confused with Windows groups, which are used in role-based access control.)true
Checks: C-47651r4_chk

Obtain the list of authorized SQL Server accounts in the system documentation. If accounts are determined to be shared, determine if individuals are first individually authenticated. If individuals are not individually authenticated before using the shared account (e.g., by the operating system or possibly by an application making calls to the database), this is a finding. (The key is individual accountability. If this can be traced, this is not a finding.) If accounts are determined to be shared, determine if they are directly accessible to end users. If so, this is a finding. Review contents of audit logs, traces and data tables to confirm that the identity of the individual user performing the action is captured. If shared identifiers are found, and not accompanied by individual identifiers, this is a finding. Note: Privileged installation accounts may be required to be accessed by the DBA or other administrators for system maintenance. In these cases, each use of the account must be logged in some manner to assign accountability for any actions taken during the use of the account.

Fix: F-46333r3_fix

Remove user-accessible shared accounts and use individual userids. Build/configure applications to ensure successful individual authentication prior to shared account access. Ensure each user's identity is received and used in audit data in all relevant circumstances. Design, develop, and implement a method to log use of any account to which more than one person has access. Restrict interactive access to shared accounts to the fewest persons possible.

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, time stamps, 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 SQL Server 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.

SQL Server Authentication does not provide for many of the authentication requirements of the DoD. In some cases workarounds are present, but the authentication is not as robust and does not provide needed functionality. Without that functionality, SQL Server is vulnerable to authentication attacks. Consideration must be given to the placement of SQL server inside a forest to ensure evaluation of risk within the environment is considered. Risk includes introduction of risk to SQL Server from other applications or workstations as well as risk from introduction of SQL server itself into an established environment. There may be situations where SQL Server Authentication must remain enabled, because of constraints imposed by a third-party application. In such a case, document the constraint in the system security plan, and obtain signed approval.true

SQL Server's 'sa' account has special privileges required to administer the database. The 'sa' account is a well-known SQL Server account name and is likely to be targeted by attackers, and is thus more prone to providing unauthorized access to the database. Since the SQL Server 'sa' is administrative in nature, the compromise of a default account can have catastrophic consequences, including the complete loss of control over SQL Server. Since SQL Server needs for this account to exist and it should not be removed, one way to mitigate this risk is to change the 'sa' account name.
Checks: C-47654r2_chk

Verify the SQL Server default 'sa' account name has been changed. Navigate to SQL Server Management Studio &gt;&gt; Object Explorer &gt;&gt; &lt;'SQL Server name'&gt; &gt;&gt; Security &gt;&gt; Logins. If SQL Server default 'sa' account name is in the 'Logins' list, this is a finding.

This requirement is intended to limit exposure due to operating from within a privileged account. SQL Server does support the organizational requirement that users of information system accounts with access to an organization-defined list of security functions or security-relevant information use non-privileged accounts and 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 SQL Server installation account requires privileges not required for SQL Server 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.
Checks: C-47655r2_chk

Open Active Directory Users and Computers (available from menus or run dsa.msc) Determine the location of the accounts or groups to be reviewed. The default is the Users container, but they could have been created or moved to an Organizational Unit (OU) that is domain specific. Right-click each DBA user. Click Properties. Click the 'Member of' tab. If any parent groups are listed that are not specific to DBA roles, this is a finding. Right-click each DBA Group. Click Properties. Select the 'Members' tab. Review the list of group members. If any account that does not represent a DBA is listed, this is a finding.

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 an organization-defined list 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 misassignment 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 by SQL Server may be executed under OS or domain accounts with unnecessary privileges. This can lead to unauthorized access to OS resources and compromise of the OS, SQL Server, or any other services provided by the host platform.
Checks: C-47657r4_chk

Determine which OS or domain accounts are used by SQL Server to run external procedures. Validate that these accounts have only the privileges necessary to perform the required functionality.

Audit of privileged activity may require physical separation, employing information systems on which the user does not have privileged access. To limit exposure and provide forensic history of activity when operating from within a privileged account or role, SQL Server does support organizational requirements that users of information system accounts, or roles, with access to an organization-defined list of security functions or security-relevant information, use non-privileged accounts, or roles, when accessing other (non-security) system functions. SQL Server provides access logging that ensures users who are granted a privileged role (or roles) have their privileged activity logged. DBAs, if assigned excessive privileges, could perform actions that endanger the information system or hide evidence of malicious activity.

Checks: C-47659r5_chk

Check to see that all required events are being audited. From the query prompt: SELECT DISTINCT traceid FROM sys.fn_trace_getinfo(0); All currently defined traces for the SQL server instance will be listed. If no traces are returned, this is a finding. Determine the trace(s) being used for the auditing requirement. In the following, replace # with a trace ID being used for the auditing requirements. From the query prompt: SELECT DISTINCT(eventid) FROM sys.fn_trace_geteventinfo(#); The following required event IDs should be listed: 14, 15, 18, 20, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 115, 116, 117, 118, 128, 129, 130, 131, 132, 133, 134, 135, 152, 153, 170, 171, 172, 173, 175, 176, 177, 178. If any of the audit event IDs required above is not listed, this is a finding. Notes: 1. It is acceptable to have the required event IDs spread across multiple traces, provided all of the traces are always active, and the event IDs are grouped in a logical manner. 2. It is acceptable, from an auditing point of view, to include the same event IDs in multiple traces. However, the effect of this redundancy on performance, storage, and the consolidation of audit logs into a central repository, should be taken into account. 3. It is acceptable to trace additional event IDs. This is the minimum list. 4. Once this check is satisfied, the DBA may find it useful to disable or modify the default trace that is set up by the SQL Server installation process. (Note that the Fix does NOT include code to do this.) Use the following query to obtain a list of all event IDs, and their meaning: SELECT * FROM sys.trace_events; 5. Because this check procedure is designed to address multiple requirements/vulnerabilities, it may appear to exceed the needs of some individual requirements. However, it does represent the aggregate of all such requirements. 6. Microsoft has flagged the trace techniques and tools used in this Check and Fix as deprecated. They will be removed at some point after SQL Server 2014. The replacement feature is Extended Events. If Extended Events are in use, and cover all the required audit events listed above, this is not a finding.

Fix: F-46341r5_fix

Create a trace that meets all auditing requirements. The script provided in the supplemental file, Trace.sql, can be used to do this; edit it as necessary to capture any additional, locally defined events.

When privileged activities are not separated from non-privileged activities, SQL Server could be subject to unauthorized changes of settings or data, which a standard user would not normally have access to outside of an authorized maintenance session. Often, administrator accounts have a unique prefix to help with identification. These accounts are located within SQL Server and may only provide access to one database instance or a limited number of database objects.

The principle of Least Privilege must be applied to the ability of users to access system tables, system management information, other configuration information, and metadata. Unauthorized access to this data could result in unauthorized changes to database objects, access controls, or SQL Server configuration. Only database administrators and other authorized users must be allowed such access. To aid in tracking and administering such permissions, individual logins must not be directly granted permissions or built-in server roles. Instead, user-defined server roles must be created, with the permissions and built-in server roles granted to them; the individual logins must be assigned to the appropriate user-defined server roles. The built-in server role "sysadmin" is a partial exception. This cannot be granted to a user-defined role, only to a login account. Most (not necessarily all) database administrators will need to be members of sysadmin. Without this, most DBCC commands and the system stored procedures/functions listed below are unavailable. The users who require such access must be documented and approved. In addition, if the site uses backup-restore software that connects to SQL Server via the Virtual Device Interface (VDI), the account used by that software must have the sysadmin role. (See Microsoft Knowledge Base article 2926557, http://support.microsoft.com/kb/2926557). If this applies, it must be documented and approved.

Separation of duties is a prevalent Information Technology control that is implemented at different layers of the information system, including the operating system and in applications. It serves to eliminate or reduce the possibility that a single user may carry out a prohibited action. Separation of duties requires that the person accountable for approving an action is not the same person who is tasked with implementing or carrying out that action. The concept of separation of duties extends to processes. The DBMS must run under a custom, dedicated OS or domain account. When the DBMS is running under a shared account, users with access to that account could inadvertently or maliciously make changes to the DBMS’s settings, files, or permissions. Similarly, related services must run under dedicated accounts where this is possible. The SQL Server Browser and Writer services are exceptions: see http://msdn.microsoft.com/en-us/library/hh510203(v=sql.110).aspx and http://msdn.microsoft.com/en-us/library/ms175536(v=sql.110).aspx.true

Examples of separation of duties include: (i) mission functions and distinct information system support functions are divided among different individuals/roles; (ii) different individuals perform information system support functions (e.g., system management, systems programming, configuration management, quality assurance and testing, network security); (iii) security personnel who administer access control functions do not administer audit functions; and (iv) different administrator accounts for different roles. Privileges granted outside the role of the application user job function are more likely to go unmanaged or without oversight for authorization. Maintenance of privileges using roles defined for discrete job functions offers improved oversight of application user privilege assignments and helps to protect against unauthorized privilege assignment.

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). These DAC concepts extend to the server level. Server instances have the potential for the access controls to propagate without limit, resulting in unauthorized access. The DBMS must ensure the recipient of server permissions possesses only the access intended. The DBMS must enforce the ability to limit unauthorized rights propagation. If propagation is not prevented, users can continue to grant rights to other users without limit.true

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.

The concept of least privilege must be applied to SQL Server 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 SQL Server accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of SQL Server and the OS. Unauthorized access to sensitive data or SQL Server control may compromise the confidentiality of personnel privacy, threaten national security, compromise a variety of other sensitive operations or lead to a loss of system control. Access controls are best managed by defining requirements based on distinct job functions and assigning access based on the job function assigned to the individual user. SQL Server's 'Unsafe assembly' permission is a high server-level privilege that must only be granted to individual administration accounts through roles, and users who have access must require this privilege to accomplish the organizational missions and/or functions. If the 'Unsafe assembly' permission is granted to roles that are unauthorized to have this privilege, then this access must be removed. Additionally, the permission must not be denied to a role, because that could disable a user's legitimate access via another role. The fix for this vulnerability specifies the use of REVOKE. Be aware that revoking a permission that is currently denied to a role or user does not necessarily disable the permission. If the user or role can inherent the permission from another role, revoking the denied permission from the user or the first role can effectively enable the inherited permission.true

The concept of least privilege must be applied to SQL Server processes, ensuring that the processes operate at privilege levels no higher than necessary to accomplish required organizational missions and/or functions. Unauthorized access to sensitive data or SQL Server control may compromise the confidentiality of personnel privacy, threaten national security, compromise a variety of other sensitive operations or lead to a loss of system control. Access controls are best managed by defining requirements based on distinct job functions and assigning access based on the job function assigned to the individual user. Privileges granted outside of SQL Server's role-based account assignments are more likely to go unmanaged and without oversight of granted access. Maintenance of privileges using roles defined for discrete job functions offers improved oversight of application user privilege assignments and helps to protect against unauthorized privilege assignment. SQL Server's 'Alter any availability group' permission is a high server-level privilege that must only be granted to individual administration accounts through roles. This administrative privilege must not be assigned directly to administrative user accounts. If administrative user accounts have direct access to administrative roles, this access must be removed. (The SQL Server installer gives this privilege to the system account "NT AUTHORITY\SYSTEM", so this account is excluded from the Check. See article KB2847723 in the Microsoft knowledge base.) Note that this does not apply to logins with names of the form '##MS...##'. These accounts are internal-use system principals provisioned by the DBMS, and required by it for specific purposes.true

The concept of least privilege must be applied to SQL Server 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 SQL Server accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of SQL Server and the OS. Unauthorized access to sensitive data or SQL Server control may compromise the confidentiality of personnel privacy, threaten national security, compromise a variety of other sensitive operations or lead to a loss of system control. Access controls are best managed by defining requirements based on distinct job functions and assigning access based on the job function assigned to the individual user. Privileges granted outside of SQL Server's role-based account assignments are more likely to go unmanaged and without oversight of granted access. Maintenance of privileges using roles defined for discrete job functions offers improved oversight of application user privilege assignments and helps to protect against unauthorized privilege assignment. SQL Server's 'Create endpoint' permission is a high server-level privilege that must only be granted to individual administration accounts through roles.

The concept of least privilege must be applied to SQL Server 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 SQL Server accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of SQL Server and the OS. Unauthorized access to sensitive data or SQL Server control may compromise the confidentiality of personnel privacy, threaten national security, compromise a variety of other sensitive operations or lead to a loss of system control. Access controls are best managed by defining requirements based on distinct job functions and assigning access based on the job function assigned to the individual user. Privileges granted outside of SQL Server's role-based account assignments are more likely to go unmanaged and without oversight of granted access. Maintenance of privileges using roles defined for discrete job functions offers improved oversight of application user privilege assignments and helps to protect against unauthorized privilege assignment. SQL Server's 'Alter any event session' permission is a high server-level privilege that must only be granted to individual administration accounts through roles. This administrative privilege must not be assigned directly to administrative user accounts (or any other user accounts).

Organizations consider the creation of additional processes, roles, and SQL Server accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of SQL Server and the OS. Unauthorized access to sensitive data or SQL Server control may compromise the confidentiality of personnel privacy, threaten national security, compromise a variety of other sensitive operations, or lead to a loss of system control. Access controls are best managed by defining requirements based on distinct job functions and assigning access based on the job function assigned to the individual user. SQL Server's 'Alter any availability group' permission is a high server-level privilege that must only be granted to individual administration accounts through roles and users. If the 'Alter any availability group' permission is granted to roles that are unauthorized to have this privilege, then this access must be removed. Additionally, the permission must not be denied to a role, because that could disable a user's legitimate access via another role. The fix for this vulnerability specifies the use of REVOKE. Be aware that revoking a permission that is currently denied to a role or user does not necessarily disable the permission. If the user or role can inherent the permission from another role, revoking the denied permission from the user or the first role can effectively enable the inherited permission.true

The concept of least privilege must be applied to SQL Server 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 SQL Server accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of SQL Server and the OS. Unauthorized access to sensitive data or SQL Server control may compromise the confidentiality of personnel privacy, threaten national security, compromise a variety of other sensitive operations, or lead to a loss of system control. Access controls are best managed by defining requirements based on distinct job functions and assigning access based on the job function assigned to the individual user. SQL Server's 'Alter any login' permission is a high server-level privilege that must only be granted to individual administration accounts through roles. If the 'Alter any login' permission is granted to roles that are unauthorized to have this privilege, then this access must be removed. Additionally, the permission must not be denied to a role, because that could disable a user's legitimate access via another role. The fix for this vulnerability specifies the use of REVOKE. Be aware that revoking a permission that is currently denied to a role or user does not necessarily disable the permission. If the user or role can inherent the permission from another role, revoking the denied permission from the user or the first role can effectively enable the inherited permission.true

The concept of least privilege must be applied to SQL Server 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 SQL Server accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of SQL Server and the OS. Unauthorized access to sensitive data or SQL Server control may compromise the confidentiality of personnel privacy, threaten national security, compromise a variety of other sensitive operations, or lead to a loss of system control. Access controls are best managed by defining requirements based on distinct job functions and assigning access based on the job function assigned to the individual user. SQL Server's 'Alter any credential' permission is a high server-level privilege that must only be granted to individual administration accounts through roles. If the 'Alter any credential' permission is granted to roles that are unauthorized to have this privilege, then this access must be removed. Additionally, the permission must not be denied to a role, because that could disable a user's legitimate access via another role. The fix for this vulnerability specifies the use of REVOKE.

Non-DAC controls are determined by policy makers and are managed centrally or by a central authority. These controls must not be changed at the discretion of ordinary application users. Data protection requirements may result in a non-DAC policy being specified as part of the application design. Non-DACs are employed at the application level to restrict and control access to application data, thereby providing increased information security for the organization. SQL Server Non-DAC is maintained through the use of Roles. Roles are set up within SQL Server to grant user accounts read and/or write permissions to system objects: databases, tables, columns, etc. After a role is created, user accounts can be assigned to a role granting them permissions of that role. If users have permissions to database objects that they are not authorized to have, the user account that has access to the unauthorized database object must be removed from the role that grants that access. Policy rule sets would be developed to establish that each user receives only the information to which the user is authorized. Frequently, roles grant access to multiple privileges; if a user is authorized and determined to need access to authorized privilege granted by a role, and unauthorized for other privileges of that same role, it may be necessary to split the privileges of one role into two roles.

Once an attacker establishes initial access to a system, they often attempt to create a persistent method of re-establishing access. One way to accomplish this is for the attacker to modify an existing account for later use. Notification of account creation is one method and best practice for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the creation of application user accounts and notifies administrators and/or application owners exist. Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes. To address the multitude of policy based access requirements, many application developers choose to integrate their applications with enterprise level authentication/access mechanisms that meet or exceed access control policy requirements. Such integration allows the application developer to off-load those access control functions and focus on core application features and functionality.

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. Remote network and system access is accomplished by leveraging common communication protocols to establish a remote connection. These connections will typically originate over either the public Internet or the Public Switched Telephone Network (PSTN). Neither of these internetworking mechanisms is private or secure, and they do not by default restrict access to networked resources once connectivity is established. Numerous best practices are employed to protect remote connections, such as utilizing encryption to protect data sessions and firewalls to restrict and control network connectivity. In addition to these protections, auditing must also be utilized in order to track system activity, assist in diagnosing system issues, and provide evidence needed for forensic investigations post security incident.

From the query prompt: SELECT DISTINCT(eventid) FROM sys.fn_trace_geteventinfo(#); The following required event IDs should be listed: 14, 15, 18, 20, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 115, 116, 117, 118, 128, 129, 130, 131, 132, 133, 134, 135, 152, 153, 170, 171, 172, 173, 175, 176, 177, 178. If any of the audit event IDs required above is not listed, this is a finding. Notes: 1. It is acceptable to have the required event IDs spread across multiple traces, provided all of the traces are always active, and the event IDs are grouped in a logical manner. 2. It is acceptable, from an auditing point of view, to include the same event IDs in multiple traces. However, the effect of this redundancy on performance, storage, and the consolidation of audit logs into a central repository, should be taken into account. 3. It is acceptable to trace additional event IDs. This is the minimum list. 4. Once this check is satisfied, the DBA may find it useful to disable or modify the default trace that is set up by the SQL Server installation process. (Note that the Fix does NOT include code to do this.) Use the following query to obtain a list of all event IDs, and their meaning: SELECT * FROM sys.trace_events; 5. Because this check procedure is designed to address multiple requirements/vulnerabilities, it may appear to exceed the needs of some individual requirements. However, it does represent the aggregate of all such requirements. 6. Microsoft has flagged the trace techniques and tools used in this Check and Fix as deprecated. They will be removed at some point after SQL Server 2014. The replacement feature is Extended Events. If Extended Events are in use, and cover all the required audit events listed above, this is not a finding.

Fix: F-46698r7_fix

Create a trace that meets all auditing requirements. The script provided in the supplemental file, Trace.sql, can be used to do this; edit it as necessary to capture any additional, locally defined events.

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. One way SQL Server can limit exposure to DoS attacks is to restrict the number of connections that can be opened by a single user. SQL Server supports this through the use of logon triggers. (Note, however, that this need not be the only, or even the principal, means for satisfying this requirement. Depending on the architecture and capabilities of the network and application, a network device or an application may be more suitable for providing this protection.) When determining the appropriate values for this limit, take the characteristics of the various kinds of user into account, and bear in mind that some applications and some users may need to have multiple sessions open. For example, while a standard account using a simple application may never need more than, say, five connections, a database administrator using SQL Server Management Studio may need significantly more, because each tab in that application counts as a distinct session. Architectural note: In SQL Server, a count of active sessions by user can be obtained from one of the dynamic management views. For example: SELECT original_login_name, count(*) FROM sys.dm_exec_sessions WHERE is_user_process = 1 GROUP BY original_login_name; However, for this to return an accurate count in a logon trigger, the user would have to have the View Server State privilege. (Without this privilege, the trigger sees information only about the current session, so would always return a count of one.) View Server State would give that user access to a wide swath of information about the server, violating SQL2-00-004100. One way to avoid this exposure is to create a summary table, and a view of that table that restricts each user to seeing his/her own count, and establish a frequently-run background job to refresh the table (using the above query or similar). The logon trigger then queries the view to obtain a count that is accurate enough for most purposes.true
