AU-13 Monitoring for Information Disclosure
High-Level Description
Family: Audit and Accountability (AU)
Framework: NIST SP 800-53 Rev 5
Unauthorized disclosure of information is a form of data leakage. Open-source information includes social networking sites and code-sharing platforms and repositories. Examples of organizational information include personally identifiable information retained by the organization or proprietary information generated by the organization.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AU-13 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.
