Mapped to NIST 800-171 Requirement: 3.3.1
CMMC Assessment Objective: AU.L2-3.3.1[e]
What This Objective Means
You’ve:
• Identified what can be logged (AU.L2-3.3.1[a])
• Defined what must be logged (AU.L2-3.3.1[b])
• Configured your systems to generate those logs (AU.L2-3.3.1[c])
• Reviewed logs to see what is being generated (AU.L2-3.3.1[d])
Now, this final step confirms that what you’re logging matches your documented requirements. This means comparing your actual logs against your defined list of auditable event types and verifying that all required events appear as expected.
Why It Matters
Logging gaps often go unnoticed until it’s too late. This objective ensures that:
• Your system logging practices align with your stated security expectations
• Auditors can clearly trace your logging practices to your policies
• Your organization has complete coverage of defined audit events for investigation and compliance
How to Implement It
• Maintain a list or matrix of required auditable events
• Pull audit logs from representative systems
• Review log entries to ensure:
◦ Each defined auditable event is recorded
◦ Logs include critical fields (timestamp, user, system, event details)
• Perform spot-checks regularly and during pre-assessment readiness reviews
• Document log samples and compare against your policy-defined audit event list
Evidence the Assessor Will Look For
• Documentation of your required audit events (defined in policy or SSP)
• Actual log records showing those events have occurred and been captured
• A mapping or cross-reference that ties your required events to real log entries
• Internal audits or test records confirming completeness
Common Gaps
• Required events are defined but not logged (e.g., user creation, failed logins)
• Logs contain partial data or omit critical event details
• Logging coverage varies across systems without documentation
How Cuick Trac Helps
Cuick Trac supports this control by:
• Providing a predefined list of auditable events aligned with CMMC expectations
• Capturing logs for all relevant system and user activities within the secure enclave
• Supporting audit trail verification with exportable logs and cross-reference documentation
• Helping organizations validate log completeness against their policies
With Cuick Trac, there’s no guesswork—what needs to be logged is logged, and you can prove it.
Final CTA
Policy without matching logs is just theory.
