SC-50 Software-enforced Separation and Policy Enforcement
High-Level Description
Family: System and Communications Protection (SC)
Framework: NIST SP 800-53 Rev 5
System owners may require additional strength of mechanism to ensure domain separation and policy enforcement for specific types of threats and environments of operation.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SC-50 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.
