MA-3(3) Prevent Unauthorized Removal
Enhancement of: MA-3
High-Level Description
Family: Maintenance (MA) Framework: NIST SP 800-53 Rev 5
Organizational information includes all information owned by organizations and any information provided to organizations for which the organizations serve as information stewards.
What to Check
- Verify MA-3(3) Prevent Unauthorized Removal is documented in SSP
- Validate all 4 control requirements are implemented
- Confirm control is operating effectively
- Review evidence of continuous monitoring for MA-3(3)
- Verify enhancement builds upon base control MA-3
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for MA-3(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.
