Mapped to NIST 800-171 Requirement: 3.7.2
CMMC Assessment Objective: MA.L2-3.7.2[b]
What This Objective Means
This control is about verifying that your maintenance control structure is visible on paper. It includes documentation of:
• Who is authorized to perform maintenance
• What systems or components are affected
• What procedures must be followed
• How tools and software used during maintenance are managed
• Any security or monitoring controls in place during maintenance windows
Without documentation, there’s no assurance the controls exist—or are being followed.
Why It Matters
Poorly documented controls lead to:
• Inconsistent or insecure maintenance practices
• Unauthorized personnel performing work on sensitive systems
• Use of unapproved tools or devices
• Failed audits due to lack of verifiable procedures
Written guidance ensures everyone follows the same secure process.
How to Implement It
1. Include Maintenance Controls in Key Documents
• Access Control Policy
• Configuration Management Plan
• Incident Response Plan (for emergency maintenance)
• System Security Plan (SSP)
2. Document:
• Roles and responsibilities
• Allowed maintenance types (routine vs. emergency)
• Approval and notification workflows
• Required security procedures (e.g., disabling remote access afterward, malware scanning of tools)
3. Describe Tool Management
• What tools are authorized
• How external media/devices are screened
• Any patch management platforms or automation software used
4. Reference Logging and Oversight
• Detail how maintenance activities are logged and reviewed
• Link to your auditing or change control processes
Evidence the Assessor Will Look For
• Policy and procedure documents explicitly detailing system maintenance controls
• Lists of authorized individuals and approved tools
• Maintenance access protocols
• Change tickets or maintenance logs referencing your documented procedures
• Screenshots or references to policy repositories
Common Gaps
• Maintenance policies are verbal or outdated
• No distinction between routine and non-routine maintenance
• No documented controls for tools or access used during updates
• Documentation doesn’t match real-world maintenance practices
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Providing templates for documenting maintenance roles, controls, and procedures
• Centralizing system security plan and access control documentation
• Ensuring documentation matches actual maintenance workflows within the enclave
• Logging all maintenance activities in alignment with your defined controls
• Helping prepare policy packets for assessment and audit readiness
With Cuick Trac, what you do—and how you do it—is documented, traceable, and compliant.
Final CTA
Policy without documentation is just wishful thinking.
