Information
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. If personnel are not notified of failed security verification tests, they will not be able to take corrective action and the unsecure condition(s) will remain. Notifications provided by information systems include messages to local computer consoles, and/or hardware indications, such as lights.
The DNS server should be configured to generate audit records whenever a self-test fails. The OS/NDM is responsible for generating notification messages related to this audit record.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Implement a third-party monitoring system to detect and notify the ISSO/ISSM/DNS administrator if functionality of Secure Updates has been removed or broken or, at a minimum, document and implement a procedure to review the diagnostic logs on a routine basis every day.
