AU-16(2) Sharing of Audit Information
Enhancement of: AU-16
High-Level Description
Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5
Due to the distributed nature of the audit information, cross-organization sharing of audit information may be essential for effective analysis of the auditing being performed. For example, the audit records of one organization may not provide sufficient information to determine the appropriate or inappropriate use of organizational information resources by individuals in other organizations. In some instances, only individuals’ home organizations have the appropriate knowledge to make such determinations, thus requiring the sharing of audit information among organizations.
What to Check
- Verify AU-16(2) Sharing of Audit Information is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AU-16(2)
- Verify enhancement builds upon base control AU-16
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AU-16(2) 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.
