CP-6(3) Accessibility
Enhancement of: CP-6
High-Level Description
Family: Contingency Planning (CP)
Framework: NIST SP 800-53 Rev 5
Area-wide disruptions refer to those types of disruptions that are broad in geographic scope with such determinations made by organizations based on organizational assessments of risk. Explicit mitigation actions include duplicating backup information at other alternate storage sites if access problems occur at originally designated alternate sites or planning for physical access to retrieve backup information if electronic accessibility to the alternate site is disrupted.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for CP-6(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.

Control Statement
Identify potential accessibility problems to the alternate storage site in the event of an area-wide disruption or disaster and outline explicit mitigation actions.
Implementation Guidance
Area-wide disruptions refer to those types of disruptions that are broad in geographic scope with such determinations made by organizations based on organizational assessments of risk. Explicit mitigation actions include duplicating backup information at other alternate storage sites if access problems occur at originally designated alternate sites or planning for physical access to retrieve backup information if electronic accessibility to the alternate site is disrupted.
