Mapped to NIST 800-171 Requirement: 3.2.3
CMMC Assessment Objective: AT.L2-3.2.3[a]
What This Objective Means
Not everyone in your organization needs deep technical training—but everyone who interacts with CUI must be trained on:
• How to recognize CUI (based on markings, context, or content)
• How to handle it in compliance with policies and federal regulations
• What to do if they see CUI mishandled or misclassified
This objective focuses on making sure you know who those people are, so they receive the right training at the right time.
Why It Matters
Improper handling of CUI is one of the most common causes of compliance violations. Without training:
• CUI may be sent over unencrypted channels
• Documents may go unmarked or shared improperly
• Personnel may not recognize when data should be protected
Identifying training recipients ensures everyone who touches CUI knows how to treat it.
How to Implement It
• Start by identifying all users who:
◦ Access or generate CUI
◦ Handle data from government contracts or DFARS-covered projects
◦ Support systems or workflows that process CUI
• Document who these users are and what roles they fill
• Update onboarding processes to ensure new hires are flagged
• Schedule periodic reviews of role-to-training mappings
Evidence the Assessor Will Look For
• A list or matrix of personnel tied to CUI-handling responsibilities
• Documentation of how training eligibility is determined
• Role descriptions or access logs that justify inclusion
• HR or IT workflows showing how training requirements are assigned
Common Gaps
• All users receive general security training, but not CUI-specific content
• No distinction between users who handle CUI and those who don’t
• Training assigned based on assumption, not role or responsibility
