Rules, Groups, and Values defined within the XCCDF Benchmark

  • SQL Server Replication Xps 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 the ...

  • SRG-APP-000516-DB-000363

    Group
  • If the SQL Server Browser Service is specifically required and approved, SQL instances must be hidden.

    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 t...

  • 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 vulnerabilit...
    Rule High Severity
  • SQL Server must be configured to utilize 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 o...
    Rule Medium Severity
  • 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 t...
    Rule High Severity
  • SQL Server must protect against a user falsely repudiating by ensuring all accounts are individual, unique, and not shared.

    Non-repudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving info...
    Rule Medium Severity
  • SQL Server must protect against a user falsely repudiating by ensuring only clearly unique Active Directory user accounts can connect to the instance.

    Non-repudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving info...
    Rule Medium Severity
  • 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 ...
    Rule Medium Severity
  • SQL Server must generate audit records when successful/unsuccessful attempts to retrieve privileges/permissions 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 availa...
    Rule Medium Severity
  • SQL Server must by default shut down upon audit failure, to include the unavailability of space for more audit log records; or must be configurable to shut down upon audit failure.

    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. Audit processing failures include: software/hardware errors; fa...
    Rule Medium Severity
  • The audit information produced by SQL Server must be protected from unauthorized access, modification, and deletion.

    If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In ...
    Rule Medium Severity
  • 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 au...
    Rule Medium Severity
  • 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 signi...
    Rule Medium Severity
  • Default demonstration and sample databases, database objects, and applications must be removed.

    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 organizatio...
    Rule Medium Severity
  • Unused database components that are integrated in SQL Server and cannot be uninstalled 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 organizatio...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
