Previous Version:
- NIST Special Publication 800-53 Revision 4:
- SI-6: Security Function Verification
Control Statement
- Verify the correct operation of [Assignment: organization-defined security and privacy functions];
- Perform the verification of the functions specified in SI-6a [Assignment (one or more): [Assignment: organization-defined system transitional states] , upon command by user with appropriate privilege, [Assignment: organization-defined frequency] ];
- Alert [Assignment: organization-defined personnel or roles] to failed security and privacy verification tests; and
- [Assignment (one or more): shut the system down, restart the system, [Assignment: organization-defined alternative action(s)] ] when anomalies are discovered.
Supplemental Guidance
Transitional states for systems include system startup, restart, shutdown, and abort. System notifications include hardware indicator lights, electronic alerts to system administrators, and messages to local computer consoles. In contrast to security function verification, privacy function verification ensures that privacy functions operate as expected and are approved by the senior agency official for privacy or that privacy attributes are applied or used as expected.
OT Discussion
Shutting down and restarting the OT may not always be feasible upon the identification of an anomaly. These actions should be scheduled according to OT operational requirements.
Control Enhancements
SI-6(2): Automation Support for Distributed Testing
Baseline(s):
Implement automated mechanisms to support the management of distributed security and privacy function testing.
SI-6(3): Report Verification Results
Baseline(s):
Report the results of security and privacy function verification to [Assignment: organization-defined personnel or roles].
