CP-4(2) Alternate Processing Site
Enhancement of: CP-4
High-Level Description
Family: Contingency Planning (CP)
Framework: NIST SP 800-53 Rev 5
Conditions at the alternate processing site may be significantly different than the conditions at the primary site. Having the opportunity to visit the alternate site and experience the actual capabilities available at the site can provide valuable information on potential vulnerabilities that could affect essential organizational mission and business functions. The on-site visit can also provide an opportunity to refine the contingency plan to address the vulnerabilities discovered during testing.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for CP-4(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.

Control Statement
Test the contingency plan at the alternate processing site:
To familiarize contingency personnel with the facility and available resources; and
To evaluate the capabilities of the alternate processing site to support contingency operations.
Implementation Guidance
Conditions at the alternate processing site may be significantly different than the conditions at the primary site. Having the opportunity to visit the alternate site and experience the actual capabilities available at the site can provide valuable information on potential vulnerabilities that could affect essential organizational mission and business functions. The on-site visit can also provide an opportunity to refine the contingency plan to address the vulnerabilities discovered during testing.
