Enhancement of: IR-4

High-Level Description

Family: Incident Response (IR) Framework: NIST SP 800-53 Rev 5

Explicit focus on handling incidents involving insider threats provides additional emphasis on this type of threat and the need for specific incident handling capabilities to provide appropriate and timely responses.

What to Check

• Verify IR-4(6) Insider Threats is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for IR-4(6)
• Verify enhancement builds upon base control IR-4

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IR-4(6) 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.
