Mapped to NIST 800-171 Requirement: 3.1.5
CMMC Assessment Objective: AC.L2-3.1.5[c]
What This Objective Means
This objective focuses on the procedural enforcement of least privilege. While the previous objective asked whether your policies support least privilege, this one ensures your day-to-day processes do too.
Assessors will want to see clear, repeatable procedures that:
• Assign access based on role or function
• Limit access to what’s needed
• Include periodic reviews to reduce or revoke excess permissions
• Prevent the accumulation of privileges over time
Why It Matters
Least privilege is only effective when it’s embedded in how access decisions are made. Without procedures to enforce it:
• Admins might grant access “just to be safe”
• Role changes might go unreviewed
• Temporary access could become permanent
Documented procedures create consistency, accountability, and auditability.
How to Implement It
• Create access control procedures that:
◦ Define how access is approved, provisioned, and documented
◦ Link users to defined roles and responsibilities
◦ Include a step for confirming least privilege during each access assignment
◦ Require justification for administrative or elevated permissions
• Train IT and HR teams on enforcing these procedures
• Integrate least privilege checks into:
◦ Onboarding
◦ Role change requests
◦ Periodic access reviews
Evidence the Assessor Will Look For
• Written access control procedures or standard operating procedures (SOPs)
• Ticketing workflows or request forms that include least privilege verification
• Screenshots from identity or access management platforms showing role-based restrictions
• Examples of access reviews or role reductions based on least privilege enforcement
Common Gaps
• No defined access provisioning procedures—or procedures don’t mention least privilege
• Users are granted default or excessive permissions
• Access reviews are conducted but don’t adjust permissions
How Cuick Trac Helps
Cuick Trac supports this objective by:
• Embedding least privilege in every user role and provisioning decision
• Restricting access by function and job role from the start
• Logging all access changes and reviews for compliance and audit support
• Offering procedural templates that align with CMMC access control requirements
With Cuick Trac, least privilege isn’t an ideal—it’s a rule that your procedures follow every day.
Final CTA
The difference between policy and reality is procedure.
