The Windows DNS Server must verify the correct operation of security functions upon system startup and/or restart, upon command by a user with privileged access, and/or every 30 days.

Description
Security function is 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. Security functionality includes but is not limited to establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters. Without verification, security functions may not operate correctly, and this failure may go unnoticed. Notifications provided by information systems include, for example, electronic alerts to system administrators, messages to local computer consoles, and/or hardware indications, such as lights. The DNS server should perform self-tests, such as at server startup, to confirm that its security functions are working properly.
