cyberstrikeus IR-3(2) Coordination with Related Plans
Enhancement of: IR-3
High-Level Description
Family: Incident Response (IR) Framework: NIST SP 800-53 Rev 5
Organizational plans related to incident response testing include business continuity plans, disaster recovery plans, continuity of operations plans, contingency plans, crisis communications plans, critical infrastructure plans, and occupant emergency plans.
What to Check
- Verify IR-3(2) Coordination with Related Plans is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for IR-3(2)
- Verify enhancement builds upon base control IR-3
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for IR-3(2) 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.
