cyberstrikeus MA-4(5) Approvals and Notifications
Enhancement of: MA-4
High-Level Description
Family: Maintenance (MA) Framework: NIST SP 800-53 Rev 5
Notification may be performed by maintenance personnel. Approval of nonlocal maintenance is accomplished by personnel with sufficient information security and system knowledge to determine the appropriateness of the proposed maintenance.
What to Check
- Verify MA-4(5) Approvals and Notifications is documented in SSP
- Validate all 2 control requirements are implemented
- Confirm control is operating effectively
- Review evidence of continuous monitoring for MA-4(5)
- Verify enhancement builds upon base control MA-4
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for MA-4(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.
