Mapped to NIST 800-171 Requirement: 3.4.5
CMMC Assessment Objective: CM.L2-3.4.5[a]
What This Objective Means
This control focuses on privilege definition—ensuring that only specifically identified roles or individuals are allowed to make system-level changes, such as:
• Installing or updating software
• Modifying security or group policy settings
• Changing network configurations
• Adjusting system files or services
It helps enforce least privilege and separation of duties by limiting who can alter critical systems.
Why It Matters
Without clear authorization boundaries:
• Unauthorized users may make untracked or risky system changes
• Insider threats or accidental misconfigurations become harder to detect
• It’s difficult to verify who is responsible for system modifications
This control ensures that only qualified, authorized personnel have the ability to change your environment.
How to Implement It
• Identify roles that require change authority (e.g., system administrators, IT security leads, DevOps engineers)
• Maintain a documented list of:
◦ Users assigned to each authorized role
◦ What types of changes each role is allowed to make
• Include these assignments in:
◦ Your System Security Plan (SSP)
◦ Configuration Management Policy
◦ Role-based access control documentation
Evidence the Assessor Will Look For
• A list of authorized users and roles permitted to make system changes
• Role definitions tied to change control responsibilities
• Policy or SOPs that specify who is authorized to change what
• Onboarding or access provisioning records that align users with those roles
Common Gaps
• Everyone with admin access can make changes, but roles aren’t defined
• Privileges are granted informally without review or documentation
• Third-party or MSP users have broad access without scope limitation
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Defining and enforcing role-based privileges across the secure enclave
• Providing templates for assigning and documenting change authority by role
• Helping customers align access controls with change management policies
• Supporting audit reporting of who is authorized and who has made changes
With Cuick Trac, change privileges are clearly assigned, well-documented, and continuously monitored.
Final CTA
Not everyone should be able to change your systems.
