CP-2(3) Resume Mission and Business Functions

Enhancement of: CP-2

High-Level Description

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

Organizations may choose to conduct contingency planning activities to resume mission and business functions as part of business continuity planning or as part of business impact analyses. Organizations prioritize the resumption of mission and business functions. The time period for resuming mission and business functions may be dependent on the severity and extent of the disruptions to the system and its supporting infrastructure.

What to Check

• Verify CP-2(3) Resume Mission and Business Functions is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for CP-2(3)
• Verify enhancement builds upon base control CP-2

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CP-2(3) 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.
