MA-5(3) Citizenship Requirements for Classified Systems
Enhancement of: MA-5
High-Level Description
Family: Maintenance (MA)
Framework: NIST SP 800-53 Rev 5
Personnel who conduct maintenance on organizational systems may be exposed to classified information during the course of their maintenance activities. If access to classified information on organizational systems is restricted to U.S. citizens, the same restriction is applied to personnel performing maintenance on those systems.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for MA-5(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.
