MS SQL Server 2014 Instance Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The role(s)/group(s) used to modify database structure (including but not necessarily limited to tables, indexes, storage, etc.) and logic modules (stored procedures, functions, triggers, links to software external to SQL Server, etc.) must be restricted to authorized users.

    If SQL Server were to allow any user to make changes to database structure or logic, then those changes might be implemented without undergoing the appropriate testing and approvals that are part o...
    Rule Medium Severity
  • SQL Server must use NIST FIPS 140-2 or 140-3 validated cryptographic modules for cryptographic operations.

    Use of weak or not validated cryptographic algorithms undermines the purposes of utilizing encryption and digital signatures to protect data. Weak algorithms can be easily broken and not validated ...
    Rule High Severity
  • SQL Server must automatically terminate a user session after organization-defined conditions or trigger events requiring session disconnect.

    This addresses the termination of user-initiated logical sessions in contrast to the termination of network connections that are associated with communications sessions (i.e., network disconnect). ...
    Rule Medium Severity
  • SQL Server must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.

    In order to ensure sufficient storage capacity for the audit logs, SQL Server must be able to allocate audit record storage capacity. Although another requirement (SRG-APP-000515-DB-000318) mandate...
    Rule Medium Severity
  • SQL Server must prohibit user installation of logic modules (stored procedures, functions, triggers, views, etc.) without explicit privileged status.

    Allowing regular users to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escal...
    Rule Medium Severity
  • SQL Server must implement and/or support cryptographic mechanisms preventing the unauthorized disclosure of organization-defined information at rest on organization-defined information system components.

    DBMSs handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. These cryptographic mec...
    Rule Medium Severity
  • Software updates to SQL Server must be tested before being applied to production systems.

    While it is important to apply SQL Server updates in a timely manner, it is also incumbent upon the database administrator and/or system administrator to ensure that their deployment will not inter...
    Rule Medium Severity
  • SQL Server must produce Trace or Audit records when security objects are accessed.

    Changes to the security configuration must be tracked. This requirement applies to situations where security data is retrieved or modified via data manipulation operations, as opposed to via SQL ...
    Rule Medium Severity
  • SQL Server must generate Trace or Audit records when privileges/permissions are deleted.

    Changes in the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized elevation or restriction of privileges could go undetected. Elevat...
    Rule Medium Severity
  • SQL Server must generate Trace or Audit records for all privileged activities or other system-level access.

    Without tracking privileged activity, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. System documentation...

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.
