SP_800_171_03.11.03 03.11.03

High-Level Description

Family: Risk Assessment Framework: NIST SP 800-171 Rev 3 Applicability: Systems processing, storing, or transmitting CUI

03.11.03

What to Check

• Verify SP_800_171_03.11.03 03.11.03 is implemented for CUI systems
• Review SSP documentation for SP_800_171_03.11.03
• Validate CMMC Level 2 assessment objective for SP_800_171_03.11.03
• Confirm POA&M addresses any gaps for SP_800_171_03.11.03

How to Test

Step 1: Review System Security Plan

Examine the SSP for SP_800_171_03.11.03 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.
