Mapped to NIST 800-171 Requirement: 3.1.5
CMMC Assessment Objective: AC.L2-3.1.5[b]
What This Objective Means
This objective looks at whether the principle of least privilege is reflected in your written access control policies. Specifically, your policy should state that:
• Users only receive the minimum access necessary to perform their roles
• Privileged or administrative access must be justified and controlled
• Excess access must be removed during user reviews or role changes
It’s about making least privilege a formal requirement, not an informal practice.
Why It Matters
If your policy doesn’t require least privilege:
• You may over-provision user accounts “just in case”
• Access reviews and deprovisioning may be inconsistent or incomplete
• Auditors won’t have a policy basis to verify enforcement
Making least privilege a policy standard sets clear expectations for secure access decisions across the organization.
How to Implement It
• Review your current access control policy
• Add or revise language to explicitly require:
◦ Least privilege for all users, roles, and service accounts
◦ Review of access rights during onboarding, offboarding, and role changes
◦ Restrictions on privileged access to administrative functions
• Include references to how least privilege is applied (e.g., RBAC, access request forms)
Evidence the Assessor Will Look For
• A current access control policy that clearly defines least privilege as a guiding principle
• Sections outlining expectations for access reviews, provisioning, and justification
• Links between policy language and supporting procedures or role definitions
• Change control history or versioning that shows recent updates to include least privilege
Common Gaps
• Least privilege is assumed but not written in policy
• Policy only addresses physical or facility access, not system access
• Policy is outdated or misaligned with current technology practices
How Cuick Trac Helps
Cuick Trac supports this objective by:
• Providing access control policy templates that include least privilege language
• Enforcing least privilege by default through predefined user roles
• Supporting role-based access provisioning aligned with your policies
• Offering audit-ready documentation that links policy to system behavior
With Cuick Trac, your access policy does more than talk about security—it defines and drives it.
Final CTA
Least privilege starts on paper, but it’s enforced in practice.
