Nonlocal Maintenance (03.07.05) Nonlocal Maintenance
High-Level Description
Family: Maintenance
Framework: NIST SP 800-171 Rev 3
Applicability: Systems processing, storing, or transmitting CUI
Approve and monitor nonlocal maintenance and diagnostic activities.
Implement multi-factor authentication and replay resistance in the establishment of nonlocal maintenance and diagnostic sessions.
Terminate session and network connections when nonlocal maintenance is completed.
What to Check
How to Test
Step 1: Review System Security Plan
Examine the SSP for Nonlocal Maintenance (03.07.05) 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.

Remediation Guide
Requirement Statement
Approve and monitor nonlocal maintenance and diagnostic activities.
Implement multi-factor authentication and replay resistance in the establishment of nonlocal maintenance and diagnostic sessions.
Terminate session and network connections when nonlocal maintenance is completed.
Supplemental Guidance
Nonlocal maintenance and diagnostic activities are conducted by individuals who communicate through an external or internal network. Local maintenance and diagnostic activities are carried out by individuals who are physically present at the location of the system and not communicating across a network connection. Authentication techniques used to establish nonlocal maintenance and diagnostic sessions reflect the requirements in 03.05.01.
