What to Check
How to Test
Step 1: Review System Security Plan
Examine the SSP for Identifier Management (03.05.05) implementation description and responsible parties.
Step 2: Assess Implementation
# Verify security controls protecting CUI
# Check access controls, encryption, monitoring as applicable
# For Linux systems:
ls -la /etc/security/ 2>/dev/null
grep -r "CUI\|controlled" /etc/security/ 2>/dev/null
# For cloud:
# Use cloud-audit-mcp tools to assess posture
Step 3: CMMC Assessment Validation
Verify this requirement passes CMMC Level 2 assessment methodology per SP 800-171A Rev 3.
