Mapped to NIST 800-171 Requirement: 3.1.16
CMMC Assessment Objective: AC.L2-3.1.16[b]
What This Objective Means
This is a technical enforcement check that builds on AC.L2-3.1.16[a]. Now that you’ve defined who can access CUI remotely and under what conditions, this objective verifies whether your system configurations align with those rules.
In short: are only the right people getting in—and only through approved channels?
Why It Matters
If remote access isn’t restricted at the system level:
• Unauthorized users could connect without detection
• CUI may be exposed through unmonitored devices or platforms
• Policy intent won’t translate into practical protection
Security depends on system-level enforcement of access rules—not just documentation.
How to Implement It
• Configure remote access platforms (VPN, RDP, cloud portals) to:
◦ Require authentication (preferably MFA)
◦ Restrict access to specific user accounts or roles
◦ Block guest, shared, or generic accounts
• Limit access by:
◦ Device (company-managed only)
◦ Network (IP whitelisting, geo-blocking)
◦ Time of day or usage window (if required)
• Use group memberships or access control lists (ACLs) to enforce remote access rights
• Regularly review who has remote access permissions and remove unused access
Evidence the Assessor Will Look For
• VPN, firewall, or remote desktop configurations showing only approved users can connect
• Role-based access controls (RBAC) limiting remote access to eligible users
• Session logs confirming access attempts align with approved users/devices
• Screenshots showing enforcement of login, MFA, and access restrictions
Common Gaps
• Policy says remote access is limited, but all domain users can connect
• Shared admin accounts used for remote sessions
• Lack of monitoring or alerting for unauthorized remote access attempts
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Allowing remote access only via secure, predefined channels with built-in MFA and encryption
• Enforcing role-based access controls that align with your authorization rules
• Logging every remote access session and tying it to a verified user account
• Preventing access from unauthorized devices or IP ranges
With Cuick Trac, only the right users can reach the right systems—on your terms.
