cyberstrikeus AU-6(3) Correlate Audit Record Repositories
Enhancement of: AU-6
High-Level Description
Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5
Organization-wide situational awareness includes awareness across all three levels of risk management (i.e., organizational level, mission/business process level, and information system level) and supports cross-organization awareness.
What to Check
- Verify AU-6(3) Correlate Audit Record Repositories is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AU-6(3)
- Verify enhancement builds upon base control AU-6
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AU-6(3) implementation details. Verify the organization has documented how this control is satisfied.
Step 2: Validate Implementation
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly
# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
Step 3: Test Operating Effectiveness
Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.
