Maintenance Personnel (03.07.06) Maintenance Personnel
High-Level Description
Family: Maintenance Framework: NIST SP 800-171 Rev 3 Applicability: Systems processing, storing, or transmitting CUI
Establish a process for maintenance personnel authorization. Maintain a list of authorized maintenance organizations or personnel. Verify that non-escorted personnel who perform maintenance on the system possess the required access authorizations. Designate organizational personnel with required access authorizations and technical competence to supervise the maintenance activities of personnel who do not possess the required access authorizations.
What to Check
- Verify Maintenance Personnel (03.07.06) Maintenance Personnel is implemented for CUI systems
- Review SSP documentation for Maintenance Personnel (03.07.06)
- Validate CMMC Level 2 assessment objective for Maintenance Personnel (03.07.06)
- Confirm POA&M addresses any gaps for Maintenance Personnel (03.07.06)
How to Test
Step 1: Review System Security Plan
Examine the SSP for Maintenance Personnel (03.07.06) 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.

Requirement Statement
Establish a process for maintenance personnel authorization. Maintain a list of authorized maintenance organizations or personnel. Verify that non-escorted personnel who perform maintenance on the system possess the required access authorizations. Designate organizational personnel with required access authorizations and technical competence to supervise the maintenance activities of personnel who do not possess the required access authorizations.
Supplemental Guidance
Maintenance personnel refers to individuals who perform hardware or software maintenance on the system, while 03.10.01 addresses physical access for individuals whose maintenance duties place them within the physical protection perimeter of the system. The technical competence of supervising individuals relates to the maintenance performed on the system, while having required access authorizations refers to maintenance on and near the system. Individuals who have not been previously identified as authorized maintenance personnel (e.g., manufacturers, consultants, systems integrators, and vendors) may require privileged access to the system, such as when they are required to conduct maintenance with little or no notice. Organizations may choose to issue temporary credentials to these individuals based on their risk assessments. Temporary credentials may be for one-time use or for very limited time periods.
Risk Assessment
| Finding | Severity | Impact |
|---|---|---|
| Maintenance Personnel (03.07.06) Maintenance Personnel not implemented | Medium | CUI Protection - Maintenance |
| Maintenance Personnel (03.07.06) partially implemented (POA&M) | Low | CMMC certification risk |
