CP-9(6) Redundant Secondary System

Enhancement of: CP-9

High-Level Description

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

The effect of system backup can be achieved by maintaining a redundant secondary system that mirrors the primary system, including the replication of information. If this type of redundancy is in place and there is sufficient geographic separation between the two systems, the secondary system can also serve as the alternate processing site.

What to Check

Verify CP-9(6) Redundant Secondary System is documented in SSP
Confirm control is operating effectively
Review evidence of continuous monitoring for CP-9(6)
Verify enhancement builds upon base control CP-9

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CP-9(6) 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.
