CP-8(2) Single Points of Failure

Enhancement of: CP-8

High-Level Description

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

In certain circumstances, telecommunications service providers or services may share the same physical lines, which increases the vulnerability of a single failure point. It is important to have provider transparency for the actual physical transmission capability for telecommunication services.

What to Check

• Verify CP-8(2) Single Points of Failure is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for CP-8(2)
• Verify enhancement builds upon base control CP-8

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CP-8(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.
