Mapped to NIST 800-171 Requirement: 3.5.9
CMMC Assessment Objective: IA.L2-3.5.7[b]
What This Objective Means
After identifying the elements of a system use notice, you must ensure those elements are actually presented to users at the system level. This applies to:
• Login screens (Windows, Linux, macOS)
• Remote desktop gateways
• VPN access portals
• Web applications
• Cloud services and administrative interfaces
The notification should appear before any login credentials are submitted, ensuring the user sees and acknowledges it before proceeding.
Why It Matters
Without a visible, pre-access system use banner:
• Users may claim they weren’t informed of monitoring
• Legal enforcement of acceptable use violations may be weakened
• Insider threats have fewer psychological or procedural deterrents
• Your environment may fall out of compliance—even if policies exist
Displaying the notice is what makes it enforceable.
How to Implement It
1. Configure Login Banners for Operating Systems
• Windows: Set via Group Policy (e.g., “Interactive Logon: Message Title and Message Text”)
• Linux/macOS: Use /etc/issue, /etc/motd, PAM settings, or GUI login customizations
2. Apply Banners Across Remote Access Points
• VPN portals
• Citrix/VMware Horizon/remote desktop solutions
• SSH login pre-messages
3. Cloud and Web Applications
• Display terms of use or warning banner before user login
• Include checkbox or acknowledgment if supported
4. Standardize Across Systems
• Use consistent language organization-wide
• Reference language defined in IA.L2-3.5.7[a]
5. Test the Display
• Verify that the banner shows before authentication
• Confirm visibility on all user entry points
Evidence the Assessor Will Look For
• Screenshots showing system use notices on login screens
• System configuration files or policy settings
• Remote access portal banners
• Documentation showing how banner language was deployed
• Test procedures confirming banner visibility
Common Gaps
• Banner is missing from remote or cloud access points
• Only some systems are configured to show the notice
• Users are not required to acknowledge the notification
• Language doesn’t match policy or legal guidance
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Deploying pre-configured system use notifications across all endpoints
• Standardizing login banners on local and remote systems
• Integrating with cloud and VPN platforms to ensure pre-login banner enforcement
• Logging banner acknowledgments (if supported) for audit readiness
• Providing clear, legally reviewed language aligned with compliance requirements
With Cuick Trac, system use notices aren’t just defined—they’re delivered where it counts.
