Finding ID Severity Title Description
V-271365 High Microsoft SQL Server products must be a version supported by the vendor. Unsupported commercial and database systems should not be used because fixes to newly identified bugs will not be implemented by the vendor. The lack of support can result in potential vulnerabilities. Systems at unsupported servicing levels or releases will not receive security updates for new vulnerabilities, which leaves them subject...
V-271324 High SQL Server must protect the confidentiality and integrity of all information at rest. This control is intended to address the confidentiality and integrity of information at rest in nonmobile 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...
V-271323 High The Service Master Key must be backed up and stored in a secure location that is not on the SQL Server. Backup and recovery of the Service Master Key may be critical to the complete recovery of the database. Creating this backup should be one of the first administrative actions performed on the server. Not having this key can lead to loss of data during recovery.
V-271322 High The Master Key must be backed up and stored in a secure location that is not on the SQL Server. Backup and recovery of the Master Key may be critical to the complete recovery of the database. Not having this key can lead to loss of data during recovery.
V-271314 High SQL Server must use NIST FIPS 140-2 or 140-3 validated cryptographic operations for encryption, hashing, and signing. Use of weak or not validated cryptographic algorithms undermines the purposes of using encryption and digital signatures to protect data. Weak algorithms can be easily broken, and not validated cryptographic modules may not implement algorithms correctly. Unapproved cryptographic modules or algorithms should not be relied on for authentication, confidentiality, or...
V-271313 High When using command-line tools such as SQLCMD in a mixed-mode authentication environment, users must use a logon method that does not expose the password. To prevent the compromise of authentication information, such as passwords and PINs, during the authentication process, the feedback from the information system must not provide any information that would allow an unauthorized user to compromise the authentication mechanism. Obfuscation of user-provided information when typed into the system is a method...
V-271310 High Confidentiality of information during transmission must be controlled through the use of an approved TLS version. Transport Layer Security (TLS) encryption is a required security setting as a number of known vulnerabilities have been reported against Secure Sockets Layer (SSL) and earlier versions of TLS. Encryption of private information is essential to ensuring data confidentiality. If private information is not encrypted, it can be intercepted and...
V-271309 High If passwords are used for authentication, SQL Server must transmit only encrypted representations of passwords. The DOD standard for authentication is DOD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and requires authorizing official (AO) approval. In such cases, passwords need to be protected at all times, and encryption is...
V-271307 High If DBMS authentication using passwords is employed, SQL Server must enforce the DOD standards for password complexity and lifetime. Windows Authentication is the default authentication mode and is much more secure than SQL Server Authentication. Windows Authentication uses Kerberos security protocol, provides password policy enforcement regarding complexity validation for strong passwords, provides support for account lockout, and supports password expiration. A connection made using Windows Authentication is sometimes called...
V-271306 High Contained databases must use Windows principals. OS/enterprise authentication and identification must be used (SRG-APP-000023-DB-000001). Native DBMS authentication may be used only when circumstances make it unavoidable and must be documented and authorizing official (AO)-approved. The DOD standard for authentication is DOD-approved PKI certificates. Authentication based on User ID and Password may be used only when it...
V-271286 High SQL Server software installation account must be restricted to authorized users. 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 have significant effects on the overall security of the system. If the system were to allow any user to make changes to software libraries,...
V-271266 High SQL Server must enforce approved authorizations for logical access to information and system resources in accordance with applicable access control policies. Authentication with a DOD-approved PKI certificate does not necessarily imply authorization to access SQL Server. To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DOD-approved PKIs, all DOD systems, including databases, must be properly configured to implement access control policies. Successful...
V-271265 High SQL Server must integrate with an organization-level authentication/access mechanism providing account management and automation for all users, groups, roles, and any other principals. Enterprise environments make account management for applications and databases challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. Managing accounts for the same person in multiple places is inefficient and prone to problems with consistency and synchronization. A comprehensive...
V-271264 High SQL Server must be configured to use the most-secure authentication method available. Enterprise environments make account management for applications and databases challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. Managing accounts for the same person in multiple places is inefficient and prone to problems with consistency and synchronization. A comprehensive...
V-274453 Medium SQL Server must protect against a user falsely repudiating by ensuring that only clearly unique Active Directory user accounts can connect to the database. Nonrepudiation of actions taken is required to maintain data 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. Nonrepudiation protects against later claims by a user of not having created, modified, or...
V-274452 Medium The SQL Server User Options feature must be disabled unless specifically required and approved. SQL Server is capable of providing a wide range of features and services. Some of the features and services, provided by default, may not be necessary, and enabling them could adversely affect system security. The "user options" option specifies global defaults for all users. A list of default query processing...
V-274451 Medium The Ole Automation Procedures feature must be disabled unless specifically required and approved. Information systems are capable of providing a wide variety of functions and services.

It is detrimental for applications to provide, or install by default, functionality exceeding requirements or...
V-274449 Medium SQL Server execute permissions to access the registry must be revoked unless specifically required and approved. 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...
V-274448 Medium The SQL Server Service Broker endpoint must use AES encryption. Information can be unintentionally or maliciously disclosed or modified during preparation for transmission, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information. Use of this requirement will be limited to situations where the data...
V-274447 Medium The SQL Server Mirroring endpoint must use AES encryption. Information can be unintentionally or maliciously disclosed or modified during preparation for transmission, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information. Use of this requirement will be limited to situations where the data...
V-274446 Medium Execution of startup stored procedures must be restricted to necessary cases only. In certain situations, to provide required functionality, a DBMS needs to execute internal logic (stored procedures, functions, triggers, etc.) and/or external code modules with elevated privileges. However, if the privileges required for execution are at a higher level than the privileges assigned to organizational users invoking the functionality applications/programs, those...
V-274445 Medium The 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...
V-274444 Medium The 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...
V-271400 Medium SQL Server must, for password-based authentication, require immediate selection of a new password upon account recovery. Password-based authentication applies to passwords regardless of whether they are used in single-factor or multifactor authentication. Long passwords or passphrases are preferable over shorter passwords. Enforced composition rules provide marginal security benefits while decreasing usability. However, organizations may choose to establish certain rules for password generation (e.g., minimum character length...
V-271389 Medium SQL Server must configure Customer Feedback and Error Reporting. By default, Microsoft SQL Server enables participation in the customer experience improvement program (CEIP). This program collects information about how its customers are using the product. Specifically, SQL Server collects information about the installation experience, feature usage, and performance. This information helps Microsoft improve the product to better meet customer...
V-271388 Medium SQL Server must configure SQL Server Usage and Error Reporting Auditing. By default, Microsoft SQL Server enables participation in the customer experience improvement program (CEIP). This program collects information about how its customers are using the product. Specifically, SQL Server collects information about the installation experience, feature usage, and performance. This information helps Microsoft improve the product to better meet customer...
V-271387 Medium The SQL Server Browser service must be disabled unless specifically required and approved. The SQL Server Browser simplifies the administration of SQL Server, particularly when multiple instances of SQL Server coexist on the same computer. It avoids the need to hard-assign port numbers to the instances and to set and maintain those port numbers in client systems. It enables administrators and authorized users...
V-271385 Medium The system SQL Server must off-load audit data to a separate log management facility; this must be continuous and in near real time for systems with a network connection to the storage facility and weekly or more often for stand-alone systems. Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. The system SQL Server may write audit records to database tables, to files in the file system, to other kinds of local repository,...
V-271381 Medium SQL Server must generate audit records for all direct access to the database(s). In this context, direct access is any query, command, or call to SQL Server that comes from any source other than the application(s) that it supports. Examples would be the command line or a database management utility program. The intent is to capture all activity from administrative and nonstandard sources.
V-271375 Medium SQL Server must generate audit records when successful and unsuccessful logons or connection attempts occur. For completeness of forensic analysis, it is necessary to track who/what (a user or other principal) logs on to SQL Server. It is also necessary to track failed attempts to log on to SQL Server. While positive identification may not be possible in a case of failed authentication, as much...
V-271370 Medium SQL Server must generate audit records when successful and unsuccessful attempts to modify or delete security objects occur. Changes and deletions of the database objects (tables, views, procedures, functions) that record and control permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized changes to the security subsystem could go undetected. The database could be severely compromised or rendered inoperative. To...
V-271364 Medium Security-relevant software updates to SQL Server must be installed within the time period directed by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs). Security flaws with software applications, including database management 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...
V-271362 Medium When invalid inputs are received, the SQL Server must behave in a predictable and documented manner that reflects organizational and system objectives. A common vulnerability is unplanned behavior when invalid inputs are received. This requirement guards against adverse or unintended system behavior caused by invalid inputs, where information system responses to the invalid input may be disruptive or cause the system to fail into an unsafe state. The behavior will be derived...
V-271359 Medium SQL Server must maintain a separate execution domain for each executing process. Database management systems can maintain separate execution domains for each executing process by assigning each process a separate address space. Each process has a distinct address space so that communication between processes is controlled through the security functions, and one process cannot modify the executing code of another process. Maintaining...
V-271358 Medium SQL Server services must be configured to run under unique dedicated user accounts. Database management systems can maintain separate execution domains for each executing process by assigning each process a separate address space. Each process has a distinct address space so that communication between processes is controlled through the security functions, and one process cannot modify the executing code of another process. Maintaining...
V-271351 Medium SQL Server must produce audit records when attempts to modify SQL Server configuration and privileges occur within the database(s). Without auditing the enforcement of access restrictions against changes to configuration, it would be difficult to identify attempted attacks, and an audit trail would not be available for forensic investigation for after-the-fact actions. Enforcement actions are the methods or mechanisms used to prevent unauthorized changes to configuration settings. Enforcement action...
V-271350 Medium SQL Server must enforce access restrictions associated with changes to the configuration of the instance. Failure to provide logical access restrictions associated with changes to configuration may have significant effects on the overall security of the system. When dealing with access restrictions pertaining to change control, it should be noted that any changes to the hardware, software, and/or firmware components of the information system can...
V-271349 Medium Windows must enforce access restrictions associated with changes to the configuration of the SQL Server instance. Failure to provide logical access restrictions associated with changes to configuration may have significant effects on the overall security of the system. When dealing with access restrictions pertaining to change control, it should be noted that any changes to the hardware, software, and/or firmware components of the information system can...
V-271346 Medium SQL Server must record time stamps in audit records and application data that can be mapped to Coordinated Universal Time (UTC), formerly Greenwich Mean Time (GMT). If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by SQL Server must include date and time. Time is commonly expressed in UTC, a modern continuation of GMT, or local time with an offset from...
V-271345 Medium SQL Server must provide an immediate real-time alert to appropriate support staff of all audit log failures. It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. The appropriate...
V-271344 Medium SQL Server must provide a warning to appropriate support staff when allocated audit record storage volume reaches 75 percent of maximum audit record storage capacity. Organizations are required to use a central log management system, so, under normal conditions, the audit space allocated to SQL Server on its own server will not be an issue. However, space will still be required on the server for SQL Server Audit records in transit, and, under abnormal conditions,...
V-271343 Medium SQL Server must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements. Organizations are required to use a central log management system, so, under normal conditions, the audit space allocated to SQL Server on its own server will not be an issue. However, space will still be required on the server for SQL Server Audit records in transit, and, under abnormal conditions,...
V-271342 Medium Use of credentials and proxies must be restricted to necessary cases only. In certain situations, to provide required functionality, a DBMS needs to execute internal logic (stored procedures, functions, triggers, etc.) and/or external code modules with elevated privileges. However, if the privileges required for execution are at a higher level than the privileges assigned to organizational users invoking the functionality applications/programs, those...
V-271341 Medium SQL Server must prevent nonprivileged users from executing privileged functions, to include disabling, circumventing, or altering implemented security safeguards/countermeasures. Preventing nonprivileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges. System documentation should include a definition of the functionality considered privileged. Depending on circumstances, privileged functions can include, for example, establishing accounts, performing system integrity checks, or...
V-271334 Medium SQL Server must reveal detailed error messages only to documented and approved individuals or roles. If SQL Server provides too much information in error logs and administrative messages to the screen, this could lead to compromise. The structure and content of error messages need to be carefully considered by the organization and development team. The extent to which the information system is able to identify...
V-271332 Medium SQL Server and associated applications, when making use of dynamic code execution, must scan input data for invalid values that may indicate a code injection attack. With respect to database management systems, one class of threat is known as SQL Injection, or more generally, code injection. It takes advantage of the dynamic execution capabilities of various programming languages, including dialects of SQL. In such cases, the attacker deduces the manner in which SQL statements are being...
V-271331 Medium SQL Server and associated applications must reserve the use of dynamic code execution for situations that require it. With respect to database management systems, one class of threat is known as SQL Injection, or more generally, code injection. It takes advantage of the dynamic execution capabilities of various programming languages, including dialects of SQL. In such cases, the attacker deduces the manner in which SQL statements are being...
V-271329 Medium Access to database files must be limited to relevant processes and to authorized, administrative users. Applications, including SQL Server, must prevent unauthorized and unintended information transfer via shared system resources. Permitting only DBMS processes and authorized, administrative users to have access to the files where the database resides helps ensure that those files are not shared inappropriately and are not open to backdoor access and...
V-271328 Medium SQL Server must prevent unauthorized and unintended information transfer via shared system resources. The purpose of this control is to prevent information, including encrypted representations of information, produced by the actions of a prior user/role (or the actions of a process acting on behalf of a prior user/role) from being available to any current user/role (or current process) that obtains access to a...
V-271327 Medium SQL Server must prevent unauthorized and unintended information transfer via Instant File Initialization (IFI). The purpose of this control is to prevent information, including encrypted representations of information, produced by the actions of a prior user/role (or the actions of a process acting on behalf of a prior user/role) from being available to any current user/role (or current process) that obtains access to a...
V-271305 Medium SQL Server must uniquely identify and authenticate users (or processes acting on behalf of organizational users). To ensure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system. Organizational users include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors). Organizational users (and any processes acting on behalf of...
V-271304 Medium SQL Server must be configured to prohibit or restrict the use of organization-defined protocols as defined in the Ports, Protocols, and Services Management (PPSM) Category Assurance List (CAL) and vulnerability assessments. To prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable or restrict unused or unnecessary protocols on information systems. Applications are capable of providing a wide variety of functions and services. Some of the functions and...

It is detrimental for software products to provide, or install by default, functionality exceeding requirements or mission...
V-271287 Medium Database software, including DBMS configuration files, must be stored in dedicated directories, separate from the host OS and other 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. Multiple applications can provide a cumulative negative effect. A vulnerability and subsequent exploit...
V-271285 Medium SQL Server must limit privileges to change software modules and links to software external to SQL Server. If the system 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. Accordingly, only qualified and authorized individuals must be allowed to obtain access to information...
V-271284 Medium SQL Server must limit privileges to change software modules, to include stored procedures, functions and triggers, and links to software external to SQL Server. If the system 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. Accordingly, only qualified and authorized individuals must be allowed to obtain access to information...
V-271283 Medium SQL Server must protect its audit configuration from authorized and unauthorized access and modification. Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit data. Applications providing tools to interface with audit data will leverage user permissions and roles identifying the user accessing the tools...
V-271282 Medium The audit information produced by SQL Server must be protected from unauthorized access, modification, and deletion. 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 their advantage. To ensure the veracity of...
V-271280 Medium SQL Server must include additional, more detailed, organization-defined information in the audit records for audit events identified by type, location, or subject. Information system auditing capability is critical for accurate forensic analysis. Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. To support analysis, some types of events will need information to be logged that exceeds the basic requirements of event type, time...
V-271273 Medium SQL Server must initiate session auditing upon startup. Session auditing is for use when a user's activities are under investigation. To be sure of capturing all activity during those periods when session auditing is in use, it needs to be in operation for the whole time SQL Server is running.
V-271272 Medium SQL Server must generate audit records when attempts to access privileges, categorized information, and security objects occur. Under some circumstances, it may be useful to monitor who/what is reading privilege/permission/role information. Therefore, monitoring must be possible. DBMSs typically make such information available through views or functions. This requirement includes explicit requests for privilege/permission/role membership information. It does not refer to the implicit retrieval of privileges/permissions/role memberships that...
V-271271 Medium SQL Server must allow only the information system security manager (ISSM) (or individuals or roles appointed by the ISSM) to select which auditable events are to be audited. Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent or interfere with the auditing of critical events. Suppression of auditing could permit an adversary to evade detection. Misconfigured audits can degrade the system's performance by overwhelming the...
V-271270 Medium SQL Server must be configured to generate audit records for DOD-defined auditable events within all DBMS/database components. Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within SQL Server (e.g., process, module). Certain specific application functionalities may be audited as...
V-271269 Medium SQL Server must protect against a user falsely repudiating by ensuring all accounts are individual, unique, and not shared. Nonrepudiation of actions taken is required to maintain data 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. Nonrepudiation protects against later claims by a user of not having created, modified, or...
V-271268 Medium SQL Server must protect against a user falsely repudiating by ensuring the NT AUTHORITY SYSTEM account is not used for administration.
