Maintenance Tools (03.07.04) Maintenance Tools
High-Level Description
Family: Maintenance
Framework: NIST SP 800-171 Rev 3
Applicability: Systems processing, storing, or transmitting CUI
Approve, control, and monitor the use of system maintenance tools.
Check media with diagnostic and test programs for malicious code before it is used in the system.
Prevent the removal of system maintenance equipment containing CUI by verifying that there is no CUI on the equipment, sanitizing or destroying the equipment, or retaining the equipment within the facility.
What to Check
How to Test
Step 1: Review System Security Plan
Examine the SSP for Maintenance Tools (03.07.04) 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.
