cyberstrikeus CP-8(5) Alternate Telecommunication Service Testing
Enhancement of: CP-8
High-Level Description
Family: Contingency Planning (CP) Framework: NIST SP 800-53 Rev 5
Alternate telecommunications services testing is arranged through contractual agreements with service providers. The testing may occur in parallel with normal operations to ensure that there is no degradation in organizational missions or functions.
What to Check
- Verify CP-8(5) Alternate Telecommunication Service Testing is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for CP-8(5)
- 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(5) 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.
