Cryptographic Protection (03.13.11) Cryptographic Protection
High-Level Description
Family: System and Communications Protection Framework: NIST SP 800-171 Rev 3 Applicability: Systems processing, storing, or transmitting CUI
Cryptographic Protection
What to Check
- Verify Cryptographic Protection (03.13.11) Cryptographic Protection is implemented for CUI systems
- Review SSP documentation for Cryptographic Protection (03.13.11)
- Validate CMMC Level 2 assessment objective for Cryptographic Protection (03.13.11)
- Confirm POA&M addresses any gaps for Cryptographic Protection (03.13.11)
How to Test
Step 1: Review System Security Plan
Examine the SSP for Cryptographic Protection (03.13.11) 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.
