MA-4(7) Disconnect Verification
Enhancement of: MA-4
High-Level Description
Family: Maintenance (MA)
Framework: NIST SP 800-53 Rev 5
Verifying the termination of a connection once maintenance is completed ensures that connections established during nonlocal maintenance and diagnostic sessions have been terminated and are no longer available for use.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for MA-4(7) 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.
