AU-10(4) Validate Binding of Information Reviewer Identity
Enhancement of: AU-10
High-Level Description
Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5
Validating the binding of the information reviewer identity to the information at transfer or release points prevents the unauthorized modification of information between review and the transfer or release. The validation of bindings can be achieved by using cryptographic checksums. Organizations determine if validations are in response to user requests or generated automatically.
What to Check
- Verify AU-10(4) Validate Binding of Information Reviewer Identity is documented in SSP
- Validate all 2 control requirements are implemented
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AU-10(4)
- Verify enhancement builds upon base control AU-10
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AU-10(4) 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.
