What an assessor checks
NIST SP 800-171A breaks 3.1.9 into 2 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- [a]Determine if privacy and security notices required by CUI-specified rules are identified, consistent, and associated with the specific CUI category
- [b]Determine if privacy and security notices are displayed.

If it is open: POA&M eligibility
May be carried on a Level 2 POA&M · 1 point deducted
A 1-point requirement outside the six named exclusions - eligible to carry, and NOT MET until a closeout assessment confirms it.
A POA&M is only permitted at a score of 88 or above, and closes in one 180-day window. Check a full gap list or compute your score.
