NIST SP 800-53 PE-6: What Your Intrusion Monitoring Must Log

Intrusion monitoring is only defensible when the system produces an audit trail that security personnel can use. A federal facility should be able to reconstruct what happened, when it happened, which device reported it, who responded, and how the event was closed.

At minimum, review timestamps, device or zone identity, alarm type, operator acknowledgement, escalation path, dispatch or response action, disposition, and any associated video or access-control event. Preserve the original event and the subsequent administrative changes.

Also test clock synchronization, retention, role-based access, export capability, and alert routing. A monitoring platform that generates alarms but cannot preserve trustworthy evidence creates a control weakness at the intersection of PE-6, audit accountability, and incident response.
