AU-13(3) Unauthorized Replication of Information
Enhancement of: AU-13
High-Level Description
Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5
The unauthorized use or replication of organizational information by external entities can cause adverse impacts on organizational operations and assets, including damage to reputation. Such activity can include the replication of an organizational website by an adversary or hostile threat actor who attempts to impersonate the web-hosting organization. Discovery tools, techniques, and processes used to determine if external entities are replicating organizational information in an unauthorized manner include scanning external websites, monitoring social media, and training staff to recognize the unauthorized use of organizational information.
What to Check
- Verify AU-13(3) Unauthorized Replication of Information is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AU-13(3)
- Verify enhancement builds upon base control AU-13
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AU-13(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.
