    SV-53258r2_rule SQL2-00-023900 CCI-001297 MEDIUM SQL Server must verify there have not been unauthorized changes to SQL Server software and information. Organizations are required to employ integrity verification applications on information systems to look for evidence of information tampering, errors, and omissions. The organization is also required to employ good software engineering practices with regard to commercial off-the-shelf integrity mechanisms (e.g., parity checks, cyclical redundancy checks, and cryptographic hashes), and to use tools to automatically monitor the integrity of the information system and the applications it hosts. SQL Server opens data files and reads configuration files at system startup, system shutdown, and during abort recovery efforts.
    SV-53259r4_rule SQL2-00-023000 CCI-001328 MEDIUM The system must activate an alarm and/or automatically shut SQL Server down if a failure is detected in its software components. 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
    SV-53260r2_rule SQL2-00-022700 CCI-001311 MEDIUM SQL Server must identify potential security-relevant error conditions. 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.
    SV-53261r3_rule SQL2-00-022600 CCI-001131 HIGH SQL Server must employ cryptographic mechanisms preventing the unauthorized disclosure of information during transmission, unless the transmitted data is otherwise protected by alternative physical measures. Preventing the disclosure of transmitted information requires that applications take measures to employ some form of cryptographic mechanism in order to protect the information during transmission. This is usually achieved through the use of Transport Layer Security (TLS), SSL VPN, or IPSEC tunnel. Alternative physical protection measures include Protected Distribution Systems (PDS). PDS are used to transmit unencrypted classified NSI through an area of lesser classification or control. In as much as the classified NSI is unencrypted, the PDS must provide adequate electrical, electromagnetic, and physical safeguards to deter exploitation. Refer to NSTSSI No. 7003 for additional details on a PDS. Information in transmission is particularly vulnerable to attack. If the DBMS does not employ cryptographic mechanisms preventing unauthorized disclosure of information during transit, the information may be compromised.true
    SV-53262r2_rule SQL2-00-022400 CCI-001096 MEDIUM 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.
    SV-53263r2_rule SQL2-00-022300 CCI-001096 LOW SQL Server must limit the use of resources by priority and not impede the host from servicing processes designated as a higher priority. 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.
    SV-53264r3_rule SQL2-00-021500 CCI-001084 MEDIUM SQL Server must isolate security functions from nonsecurity functions by means of separate security domains. 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
    SV-53265r3_rule SQL2-00-021300 CCI-001199 MEDIUM SQL Server must protect data at rest and ensure confidentiality and integrity of data. This control is intended to address the confidentiality and integrity of information at rest in non-mobile devices and covers user information and system information. Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive, tape drive) within an organizational information system. Applications and application users generate information throughout the course of their application use. User-generated data, as well as, application-specific configuration data, needs to be protected. Configurations and/or rule sets for firewalls, gateways, intrusion detection/prevention systems, filtering routers, and authenticator content are examples of system information likely requiring protection. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate. If the confidentiality and integrity of SQL Server data is not protected, the data will be open to compromise and unauthorized modification. Protective measures include encryption, physical security of the facility where the storage devices reside, operating system file permissions, and organizational controls. Each of these should be applied as necessary and appropriate.
    SV-53266r3_rule SQL2-00-020400 CCI-001157 LOW SQL Server must associate and maintain security labels when exchanging information between systems. 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.
    SV-53267r3_rule SQL2-00-020300 CCI-001149 MEDIUM SQL Server must protect the integrity of publicly available information and SQL Servers configuration from unauthorized Server Roles access. The purpose of this control is to ensure organizations explicitly address the protection needs for public information and applications, with such protection likely being implemented as part of other security controls. 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.
    SV-53268r3_rule SQL2-00-020200 CCI-001149 MEDIUM SQL Server must protect the integrity of publicly available information and SQL Servers configuration from unauthorized User Mapping access. The purpose of this control is to ensure organizations explicitly address the protection needs for public information and applications, with such protection likely being implemented as part of other security controls. 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 access includes, but is not limited to, SQL Server 'User Mapping' assignments. SQL Server access to any of the three system databases (master, model, or msdb) is restricted from the publicly available user account, because this would grant more than read-only access to public information. Of the existing user-defined databases, privileges must be checked to allow only read access to publically available data. This requirement is not intended to prevent the establishment of public-facing systems for the purpose of collecting data from the public.
    SV-53269r3_rule SQL2-00-020100 CCI-001149 MEDIUM SQL Server must protect the integrity of publicly available information and applications. The purpose of this control is to ensure organizations explicitly address the protection needs for public information and applications, with such protection likely being implemented as part of other security controls. If SQL Server contains publicly available information, though not concerned with confidentiality, SQL Server OS 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 configuration information. Determine what publicly available user account is being used to access SQL Server and validate that the publicly available user account only has read access to the public data and nothing else. The OS level 'Guests' role grants connection access to the server without granting any other privileges. SQL Server configuration settings are used to grant access to the publicly available information, but this control ensures that the OS only is granted connection access to the server. This requirement is not intended to prevent the establishment of public-facing systems for the purpose of collecting data from the public.
    SV-53270r3_rule SQL2-00-020000 CCI-001149 MEDIUM SQL Server must protect the integrity of publicly available information and SQL Servers configuration from unauthorized Securables access. The purpose of this control is to ensure organizations explicitly address the protection needs for public information and applications, with such protection likely being implemented as part of other security controls. SQL Server must be configured to contain 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. A publicly available user account must not have access to the OS or SQL Server configuration information, including read access to schema information. Determine what publicly available user account is being used to access SQL Server and validate that the publicly available user account only has read access to the public data and nothing else. This read-only access does not include SQL Server 'Securables' assignments. SQL Server 'Securables' assignments grant the assignee privileges that are beyond read access to data. No public user account must have SQL Server 'Securables' privileges. Any assigned 'Securables' privileges to the public user account must be removed. Likely the only 'Server roles' assignment for the publicly available user account would be 'public'. The only other 'Server roles' that could be authorized as read-only is a user-defined 'Server role'. It is more likely that read-only access is set up at the user database instance in role(s) specifically set up for this purpose. Assignment to the user database instances are made in the 'User Mapping' highlight within a user's properties. This requirement is not intended to prevent the establishment of public-facing systems for the purpose of collecting data from the public.
    SV-53271r3_rule SQL2-00-019600 CCI-001144 HIGH SQL Server databases in the classified environment, containing classified or sensitive information, must be encrypted using approved cryptography. 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.true
    SV-53272r3_rule SQL2-00-019800 CCI-001146 MEDIUM SQL Server must employ NSA-approved cryptography to protect classified information. 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. 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.
    SV-53273r3_rule SQL2-00-018900 CCI-000804 MEDIUM SQL Server must uniquely identify and authenticate non-organizational users (or processes acting on behalf of non-organizational users). 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.
    SV-53275r2_rule SQL2-00-018700 CCI-000197 MEDIUM SQL Server must enforce password encryption for transmission. Passwords need to be protected at all times and encryption is the standard method for protecting passwords during transmission. DBMS passwords sent in clear text format across the network are vulnerable to discovery by unauthorized users. Disclosure of passwords may easily lead to unauthorized access to the database.
    SV-53276r2_rule SQL2-00-018600 CCI-000196 MEDIUM SQL Server must enforce password encryption for storage. 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.
    SV-53277r3_rule SQL2-00-018500 CCI-000770 MEDIUM SQL Server must ensure users are authenticated with an individual authenticator prior to using a shared authenticator. 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.)
    SV-53278r3_rule SQL2-00-018400 CCI-000764 MEDIUM SQL Server must uniquely identify and authenticate organizational users (or processes acting on behalf of organizational users). To ensure accountability and prevent unauthorized SQL Server access, organizational users shall be identified and authenticated. Organizational users include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors, guest researchers, individuals from allied nations). Users (and any processes acting on behalf of users) are uniquely identified and authenticated for all accesses other than those accesses explicitly identified and documented by the organization, which outlines specific user actions that can be performed on SQL Server without identification or authentication.
    SV-53279r2_rule SQL2-00-018300 CCI-000537 MEDIUM SQL Server software libraries must be periodically backed up. SQL Server backups are a critical step in maintaining data assurance and availability. System-level information includes system-state information, operating system and application software, and licenses. Backups shall be consistent with organization-defined recovery time and recovery point objectives. SQL Server depends upon the availability and integrity of its software libraries. Without backups, compromise or loss of the software libraries can prevent a successful recovery of SQL Server operations. A mixture of full and incremental server-level backups by a third-party tool that backs up those software library directories would satisfy this requirement.
    SV-53280r2_rule SQL2-00-018200 CCI-000537 MEDIUM SQL Server backups of system-level information per organization-defined frequency must be performed that is consistent with recovery time and recovery point objectives. SQL Server backups are a critical step in maintaining data assurance and availability. System-level information includes: system-state information, operating system and application software, and licenses. Backups shall be consistent with organizationally defined recovery time and recovery point objectives. SQL Server depends upon the availability and integrity of its system-level information. Without backups, compromise or loss of system-level information can prevent a successful recovery of SQL Server operations. If SQL Server system-level information is not backed up regularly this risks the loss of SQL Server data in the event of a system failure. A mixture of full and incrementally server level backups that backup the system-level information would satisfy this requirement.
    SV-53281r2_rule SQL2-00-018100 CCI-000535 MEDIUM SQL Server backup and restoration files must be protected from unauthorized access. 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.
    SV-53282r2_rule SQL2-00-017900 CCI-000535 MEDIUM SQL Server recovery procedures that are documented must be implemented and periodically tested. SQL Server backups are a critical step in maintaining data assurance and availability. User-level information is data generated by the 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 SQL Server or within any other storage media. Applications performing backups must be capable of backing up user-level information per the DoD-defined frequency. Problems with backup procedures or backup media may not be discovered until after a recovery is needed. Testing and verification of procedures provides the opportunity to discover oversights, conflicts, or other issues in the backup procedures or use of media designed to be used. Part of an overall backup and recovery methodology includes regular recovery testing. This is very important and helps to expose any issue in the recovery process (e.g., hardware, procedures, etc.).
    SV-53283r2_rule SQL2-00-017800 CCI-000535 MEDIUM SQL Server backup procedures must be defined, documented, and implemented. SQL Server backup is a critical step in maintaining data assurance and availability. User-level information is data generated by the 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 SQL Server or within any other storage media. Applications performing backups must be configured to back up user-level information per the DoD-defined frequency. SQL Server Database backups provide the required means to restore databases after compromise or loss. Backups help reduce the vulnerability to unauthorized access or hardware loss.
    SV-53284r2_rule SQL2-00-017700 CCI-000535 MEDIUM SQL Server user-level information must be backed up based on a defined frequency. 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 SQL Server or within any other storage media. Applications performing backups must be capable of backing up user-level information per the DoD defined frequency. Databases that do not backup information regularly risk the loss of that information in the event of a system failure.
    SV-53286r3_rule SQL2-00-017500 CCI-000553 HIGH SQL Server must recover to a known state that is verifiable. Application recovery and reconstitution constitutes executing an information system contingency plan comprised of 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.
    SV-53287r2_rule SQL2-00-017400 CCI-000382 MEDIUM SQL Server must support the organizational requirements to specifically prohibit or restrict the use of unauthorized functions, ports, protocols, and/or services. 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.
    SV-53288r3_rule SQL2-00-017300 CCI-000382 MEDIUM SQL Server must specifically prohibit or restrict the use of unauthorized functions and services in each instance. 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). 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.
    SV-53289r2_rule SQL2-00-017200 CCI-000381 MEDIUM Access to xp_cmdshell must be disabled. 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.
    SV-53290r3_rule SQL2-00-017100 CCI-000381 MEDIUM SQL Server default account sa must be disabled. 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
    SV-53291r2_rule SQL2-00-017000 CCI-000381 MEDIUM Unused database components which are integrated in SQL Server and cannot be uninstalled must be disabled. 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.
    SV-53292r2_rule SQL2-00-016800 CCI-000381 MEDIUM SQL Server must have the SQL Server Analysis Service (SSAS) software component removed from SQL Server if SSAS is unused. 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, yet 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. SQL Server must have the SQL Server Analysis Service (SSAS) software component removed from SQL Server if SSAS is unused.
    SV-53293r2_rule SQL2-00-016700 CCI-000381 MEDIUM SQL Server must have the SQL Server Integrated Services (SSIS) software component removed from SQL Server if SSIS is unused. 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, yet cannot be disabled.

    SV-53294r2_rule SQL2-00-016600 CCI-000381 MEDIUM SQL Server must have the SQL Server Reporting Service (SSRS) software component removed from SQL Server if SSRS is unused. 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, yet cannot be disabled.

    SV-53295r2_rule SQL2-00-016500 CCI-000381 HIGH SQL Server must have the SQL Server Data Tools (SSDT) software component removed from SQL Server if SSDT is unused. 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, yet cannot be disabled. Applications must adhere to the principles of least functionality by providing only essential capabilities. Unused and unnecessary DBMS components increase the attack vector for the DBMS by introducing additional targets for attack. By minimizing the services and applications installed on the system, the number of potential vulnerabilities is reduced. SQL Server must have the SQL Server Data Tools (SSDT) software component removed from SQL Server if SSDT is unused.

Applications must adhere to the principles of least functionality by providing only essential capabilities. Even though the very popular "AdventureWorks" database is no longer available by default, it introduces a vulnerability to SQL Server and must be removed. Demonstration and sample database objects and applications present publicly known attack points for malicious users. These demonstration and sample objects are meant to provide simple examples of coding specific functions and are not developed to prevent vulnerabilities from being introduced to the SQL Server and the OS.

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
    SV-53299r2_rule SQL2-00-015700 CCI-001499 HIGH Vendor-supported software and patches must be evaluated and patched against newly found vulnerabilities. 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.

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.

Accordingly, only qualified and authorized individuals are allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications. Access restrictions for change also include software libraries. Examples of access restrictions include: physical access controls (such as locks and access cards), logical access controls (such as ACLs), automated auditing (logging) of logical access, workflow automation, media libraries, abstract layers (e.g., changes are implemented into a third-party interface rather than directly into the information system component), and change windows (e.g., changes occur only during specified times, making unauthorized changes outside the window easy to discover).

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

    SV-53390r4_rule SQL2-00-013600 CCI-000162 MEDIUM SQL Server must protect audit information from any type of unauthorized access. 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. Some commonly employed methods include ensuring log files enjoy the proper file system permissions utilizing file system protections, and limiting log data location. Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity.true
    SV-53391r4_rule SQL2-00-014400 CCI-001352 MEDIUM SQL Server must protect the audit records generated as a result of remote access to privileged accounts and by the execution of privileged functions. 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
    SV-53396r3_rule SQL2-00-013400 CCI-000158 MEDIUM SQL Server must audit attempts to bypass access controls. 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.
    SV-53397r3_rule SQL2-00-012800 CCI-001343 MEDIUM SQL Server must shutdown immediately in the event of an audit failure, unless an alternative audit capability exists. 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
    SV-53398r2_rule SQL2-00-012600 CCI-000143 LOW SQL Server itself, or the logging or alerting mechanism the application utilizes, must provide a warning when allocated audit record storage volume reaches an organization-defined percentage of maximum audit record storage capacity. 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.
    SV-53399r2_rule SQL2-00-010500 CCI-000138 MEDIUM SQL Server auditing configuration maximum number of files must be configured to reduce the likelihood of storage capacity being exceeded, while meeting organization-defined auditing requirements. 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.

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 until the maximum number of files has been reached. 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. Therefore, the combination of max_size and max_files must be monitored to ensure that overwriting does not occur. This must also coincide with the backup process of off-loading the files.
    SV-53401r2_rule SQL2-00-010600 CCI-000137 MEDIUM SQL Server must have allocated audit record storage capacity to meet the organization-defined requirements for saving audit record information. SQL Server does not have the ability to be cognizant of potential audit log storage capacity issues. During the installation and/or configuration process, SQL Server should detect and determine if adequate storage capacity has been allocated for audit logs. During the installation process, a notification may be provided to the installer indicating, based on the auditing configuration chosen and the amount of storage space allocated for audit logs, the amount of storage capacity available is not sufficient to meet storage requirements. SQL Server is not able to send out notice based on adequate storage capacity allocated for the audit logs.

SQL Server 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. SQL Server does have a means available to add organizationally defined additional, more detailed information in the audit event records. These events may be identified by type, location, or subject. An example of more detailed information the organization may require in audit records could be the name of the application where the request is coming from. Some organizations may determine that more detailed information is required for specific database event types. If this information is not available, it could negatively impact forensic investigations into user actions or other malicious events.

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 the outcome of attempted actions. 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.

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.

    SV-53409r4_rule SQL2-00-023700 CCI-000166 LOW SQL Server must protect against an individual using a shared account from falsely denying having performed a particular action. Non-repudiation of actions taken is required in order to maintain application integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e.g., indicating concurrence or signing a contract), and receiving a message. Non-repudiation protects individuals against later claims by an author of not having authored a particular document, a sender of not having transmitted a message, a receiver of not having received a message, or a signatory of not having signed a document. 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
    SV-53410r3_rule SQL2-00-011400 CCI-000172 MEDIUM SQL Server must generate audit records for the DoD-selected list of auditable events. 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.true
    SV-53412r2_rule SQL2-00-010200 CCI-000040 LOW SQL Server default account sa must have its name changed. 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.
    SV-53413r2_rule SQL2-00-010100 CCI-000040 MEDIUM Use of the SQL Server software installation account must be restricted to SQL Server software installation. 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.

The check and fix are based on the assumption that Role-Based Access Control (RBAC) is in effect, as mandated by other STIG requirements. They further assume that, as mandated elsewhere, the privileged accounts discussed here are distinct from the accounts used by the same people when not performing privileged functions.true
    SV-53415r2_rule SQL2-00-009900 CCI-000040 MEDIUM OS accounts utilized to run external procedures called by SQL Server must have limited privileges. 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 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.
    SV-53416r2_rule SQL2-00-009800 CCI-000040 MEDIUM SQL Server DBA roles must not be assigned excessive or unauthorized privileges. This requirement is intended to limit exposure due to operating from within a privileged account or role.

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.

    SV-53418r2_rule SQL2-00-009600 CCI-000040 MEDIUM Administrators must utilize a separate, distinct administrative account when performing administrative activities, accessing database security functions, or accessing security-relevant information within SQL Server. 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.

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.
    SV-53419r3_rule SQL2-00-009400 CCI-000037 MEDIUM SQL Server must restrict access to system tables, other configuration information, and metadata to DBAs and other authorized users. 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.

    SV-53420r2_rule SQL2-00-009100 CCI-000037 MEDIUM A single SQL Server database connection configuration file (or a single set of credentials) must not be used to configure all database clients. Applications employ the concept of least privilege for specific duties and information systems (including specific functions, ports, protocols, and services). The concept of least privilege is also applied to information system processes, ensuring that the processes operate at privilege levels no higher than necessary to accomplish required organizational missions and/or functions. Organizations consider the creation of additional processes, roles, and information system accounts as necessary to achieve least privilege. Organizations also apply least privilege concepts to the design, development, implementation, and operations of information systems. Many sites distribute a single SQL Server connection configuration file to all site database users that contains network access information for all databases on the site. Such a file provides information to access SQL Server databases not required by all users that may assist in unauthorized access attempts.

    SV-53422r3_rule SQL2-00-008900 CCI-000037 MEDIUM SQL Server processes or services must run under custom, dedicated OS accounts. 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 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
    SV-53669r3_rule SQL2-00-008800 CCI-000037 MEDIUM SQL Server must enforce separation of duties through assigned information access authorizations. 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. Additionally, the person or entity accountable for monitoring the activity must be separate as well. To meet this requirement, applications, when applicable, shall be divided where functionality is based on roles and duties. 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.
    SV-53670r3_rule SQL2-00-011100 CCI-001694 MEDIUM SQL Server utilizing Discretionary Access Control (DAC) must enforce a policy that includes or excludes access to the granularity of a single user. DAC is based on the notion that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object, and in which mode (e.g., read or write). Ownership is usually acquired as a consequence of creating the object or via specified ownership assignment. DAC allows the owner to determine who will have access to objects they control. An example of DAC includes user-controlled file permissions. Including or excluding access to the granularity of a single user means providing the capability to either allow or deny access to objects (e.g., files, folders) on a per single-user basis. Databases using DAC must have the ability for the owner of an object or information to assign or revoke rights to view or modify the object or information. If the owner of an object or information does not have rights to exclude access to an object or information at a user level, users may gain access to objects and information they are not authorized to view/modify.
    SV-53671r4_rule SQL2-00-011000 CCI-001693 MEDIUM SQL Server utilizing Discretionary Access Control (DAC) must enforce a policy that limits propagation of access rights. 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
    SV-53672r3_rule SQL2-00-008500 CCI-001362 MEDIUM SQL Server must enforce DAC policy allowing users to specify and control sharing by named individuals, groups of individuals, or by both; limiting propagation of access rights; and including or excluding access to the granularity of a single user. Access control policies (e.g., identity-based policies, role-based policies, attribute-based policies) and access enforcement mechanisms (e.g., access control lists, access control matrices, cryptography) are employed by organizations to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, domains). DAC is a type of access control methodology serving as a means of restricting access to objects and data based on the identity of subjects and/or groups to which they belong. It is discretionary in the sense that application users with the appropriate permissions to access an application resource or data have the discretion to pass that permission on to another user either directly or indirectly. Data protection requirements may result in a DAC policy being specified as part of the application design. Discretionary access controls would be employed at the application level to restrict and control access to application objects and data, thereby providing increased information security for the organization. When DAC controls are employed, those controls must limit sharing to named application users, groups of users, or both. The application DAC controls must also limit the propagation of access rights and have the ability to exclude access to data down to the granularity of a single user. Databases using DAC must have the ability for the owner of an object or information to assign or revoke rights to view or modify the object or information. If the owner of an object or information does not have rights to exclude access to an object or information at a user level, users may gain access to objects and information they are not authorized to view/modify.

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

    SV-53786r3_rule SQL2-00-002200 CCI-000022 MEDIUM SQL Server must enforce non-DAC policies over users and resources where the policy rule set for each policy specifies access control information (i.e., position, nationality, age, project, time of day). 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.

    SV-53789r3_rule SQL2-00-001600 CCI-001454 MEDIUM SQL Server must ensure that remote sessions that access an organization-defined list of security functions and security-relevant information are audited. 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.

    SV-53793r4_rule SQL2-00-000100 CCI-000054 MEDIUM The number of concurrent SQL Server sessions for each system account must be limited. 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
