Mapped to NIST 800-171 Requirement: 3.1.22
CMMC Assessment Objective: AC.L2-3.1.22[b]
What This Objective Means
Your policy should make it clear that all systems must present a system use notice before access is allowed. This message should include:
• A warning that the system is for authorized use only
• A notice that activities may be monitored and recorded
• An acknowledgment that users consent to those terms by logging in
Your procedures must then explain how and where these messages are implemented and maintained.
Why It Matters
A consistent, policy-backed requirement for system use notifications helps:
• Establish user accountability
• Provide legal authority to monitor systems and investigate incidents
• Prevent unauthorized or accidental misuse of systems
Without a documented requirement, use of banners may be inconsistent—or missed entirely.
How to Implement It
• Update your access control policy to include a section that:
◦ Requires system use notices on all systems that store, process, or access CUI
◦ Specifies the content elements that must be included in the notice
• Write or update procedures to:
◦ Define how banners are configured
◦ Identify who is responsible for reviewing and maintaining them
◦ Include examples of approved language
Evidence the Assessor Will Look For
• Policy statements that mandate system use notifications
• Procedures that guide the implementation and review of login banners
• Sample banner language documented in your SSP or control implementation summary
• Revision history showing when these requirements were added or updated
Common Gaps
• System use messages are deployed, but not required by policy
• No procedure exists to guide the content, deployment, or maintenance of login banners
• Banners are inconsistent across systems, with no documented standard
How Cuick Trac Helps
Cuick Trac supports this control by:
• Providing default system use notifications with CMMC-compliant language
• Enforcing the use of banners across all Cuick Trac access portals
• Helping organizations adopt policy language and procedures that mirror secure enclave standards
• Supplying exportable documentation for inclusion in your SSP or audit package
With Cuick Trac, system use notifications are always required, visible, and enforced—by policy and configuration.
Final CTA
A login banner isn’t just best practice—it’s a policy requirement.
