What an assessor checks
NIST SP 800-171A breaks 3.8.2 into 1 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- Determine if access to CUI on system media is limited to authorized users.
- Examine
- [SELECT FROM: System media protection policy; procedures addressing media storage; physical and environmental protection policy and procedures; access control policy and procedures; security plan; system media; designated controlled areas; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with system media protection and storage responsibilities; personnel with information security responsibilities].
- Test
- [SELECT FROM: Organizational processes for storing media; mechanisms supporting or implementing secure media storage and media protection].
If it is open: POA&M eligibility
Not POA&M-eligible: above the 1-point ceiling · 3 points deducted
Worth 3 points. No requirement over 1 point may appear on a Level 2 POA&M, so this has to be closed before the assessment.
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.
