IR-4(13) Behavior Analysis
Enhancement of: IR-4
High-Level Description
Family: Incident Response (IR)
Framework: NIST SP 800-53 Rev 5
If the organization maintains a deception environment, an analysis of behaviors in that environment, including resources targeted by the adversary and timing of the incident or event, can provide insight into adversarial tactics, techniques, and procedures. External to a deception environment, the analysis of anomalous adversarial behavior (e.g., changes in system performance or usage patterns) or suspected behavior (e.g., changes in searches for the location of specific resources) can give the organization such insight.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for IR-4(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.
