# SP_800_171_03.04.07 03.04.07

## High-Level Description

**Family:** Configuration Management
**Framework:** NIST SP 800-171 Rev 3
**Applicability:** Systems processing, storing, or transmitting CUI

03.04.07

## What to Check

- [ ] Verify SP_800_171_03.04.07 03.04.07 is implemented for CUI systems
- [ ] Review SSP documentation for SP_800_171_03.04.07
- [ ] Validate CMMC Level 2 assessment objective for SP_800_171_03.04.07
- [ ] Confirm POA&M addresses any gaps for SP_800_171_03.04.07

## How to Test

### Step 1: Review System Security Plan

Examine the SSP for SP_800_171_03.04.07 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.
