What this control requires

Source: NIST SP 800-171 R3 §03.03.09 (official control text).

Why this matters

Organizations must track and investigate anomalous or suspicious security events to detect breaches, insider threats, and active attacks before they cause damage. Without structured audit review processes, malicious activity can persist undetected for months. This control requires establishing baselines for normal system behavior, analyzing audit logs for deviations, and escalating findings to incident response teams. It protects against advanced persistent threats, account compromise, data exfiltration, and privilege abuse by ensuring security events receive timely human analysis beyond automated alerting.

What evidence assessors expect

Assessors typically look for: PDF, screenshot, CSV export. FORCE coaches you through the exact implementation steps and captures each artifact in-platform.
