AU-6(9) Correlation with Information from Nontechnical Sources

Enhancement of: AU-6

High-Level Description

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

Nontechnical sources include records that document organizational policy violations related to harassment incidents and the improper use of information assets. Such information can lead to a directed analytical effort to detect potential malicious insider activity. Organizations limit access to information that is available from nontechnical sources due to its sensitive nature. Limited access minimizes the potential for inadvertent release of privacy-related information to individuals who do not have a need to know. The correlation of information from nontechnical sources with audit record information generally occurs only when individuals are suspected of being involved in an incident. Organizations obtain legal advice prior to initiating such actions.

What to Check

• Verify AU-6(9) Correlation with Information from Nontechnical Sources is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for AU-6(9)
• Verify enhancement builds upon base control AU-6

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for AU-6(9) 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.
