Framework: NIST 800-53 Audio Course

Audit Record Review, Analysis, and Reporting (AU-6) focuses on how organizations interpret and act upon the logs collected under AU-2. For exam purposes, candidates must understand that collecting audit records has no value unless those records are analyzed for indicators of compromise, anomalies, or policy violations. AU-6 requires scheduled reviews, automated correlation, and reporting to responsible officials for investigation and response. The control ensures that analysis frequency and depth align with system criticality and threat exposure.

Operationally, review processes combine automation and human oversight. SIEM dashboards highlight deviations from baselines, while analysts investigate flagged events using established escalation paths. Reports summarize patterns such as repeated failed logins, unauthorized privilege use, or irregular data transfers. Findings drive remediation, and summary metrics inform management reporting. Metrics include review completion rates, time to analyze high-severity alerts, and number of recurring issues identified. Pitfalls arise when reviews are superficial or reactive, leading to missed warning signs. By mastering AU-6, professionals demonstrate the ability to convert raw log data into actionable intelligence that sustains situational awareness and compliance readiness.
