AU-5(5) Alternate Audit Logging Capability

Enhancement of: AU-5

High-Level Description

Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5

Since an alternate audit logging capability may be a short-term protection solution employed until the failure in the primary audit logging capability is corrected, organizations may determine that the alternate audit logging capability need only provide a subset of the primary audit logging functionality that is impacted by the failure.

What to Check

Verify AU-5(5) Alternate Audit Logging Capability is documented in SSP
Confirm control is operating effectively
Review evidence of continuous monitoring for AU-5(5)
Verify enhancement builds upon base control AU-5

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for AU-5(5) 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.

Tools

Tool	Purpose	Usage
cloud-audit-mcp	Check logging configuration	`cloud_audit_logging`
AWS CLI	Review CloudTrail/CloudWatch	`aws cloudtrail describe-trails`
