CP-4 Contingency Plan Testing

High-Level Description

Family: Contingency Planning (CP) Framework: NIST SP 800-53 Rev 5

Methods for testing contingency plans to determine the effectiveness of the plans and identify potential weaknesses include checklists, walk-through and tabletop exercises, simulations (parallel or full interrupt), and comprehensive exercises. Organizations conduct testing based on the requirements in contingency plans and include a determination of the effects on organizational operations, assets, and individuals due to contingency operations. Organizations have flexibility and discretion in the breadth, depth, and timelines of corrective actions.

What to Check

Verify CP-4 Contingency Plan Testing is documented in SSP
Validate all 2 control requirements are implemented
Confirm control is operating effectively
Review evidence of continuous monitoring for CP-4

How to Test

Step 1: Review Documentation

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