Mapped to NIST 800-171 Requirement: 3.5.9
CMMC Assessment Objective: IA.L2-3.5.7[a]
What This Objective Means
Before users gain access to a system—especially one processing Controlled Unclassified Information (CUI)—they must receive a clear notification that:
• Outlines acceptable use
• States the system is monitored
• Warns that unauthorized use is prohibited
• Clarifies that continued use implies consent to monitoring
This notice is typically displayed during login or system access initiation and serves as both a legal and operational boundary-setting tool.
Why It Matters
Without a proper system use notification:
• Users may claim ignorance about acceptable use
• Legal enforcement of monitoring or disciplinary actions may be weakened
• Insider threats or policy violations may go unchallenged
• You risk failing compliance checks for basic access warnings
A well-defined notice creates transparency and accountability.
How to Implement It
1. Define Key Notification Elements At a minimum, your system use banner or notice should include:
• Authorized use only
• Monitoring is conducted
• No expectation of privacy
• Use constitutes consent to monitoring
• Consequences of misuse (e.g., disciplinary or legal action)
2. Document the Notification Language
• Include final text in your:
◦ Access Control Policy
◦ System Security Plan (SSP)
◦ IT onboarding materials
3. Tailor for Relevance
• Customize language to fit internal, contractor, or public access use cases
• Ensure language complies with applicable laws and internal HR/legal guidance
Evidence the Assessor Will Look For
• Documentation of the exact system use notification language
• Policy references showing notification requirements
• Screenshots of the banner or pop-up used before login
• Onboarding/training materials referencing user acknowledgment
Common Gaps
• No formal definition of notification content
• Notification only includes a welcome message—not legal disclaimers
• Systems present inconsistent language across platforms
• Users aren’t required to acknowledge the notice
