What an assessor checks
NIST SP 800-171A breaks 3.9.1 into 1 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- Determine if individuals are screened prior to authorizing access to organizational systems.
- Examine
- [SELECT FROM: Personnel security policy; procedures addressing personnel screening; records of screened personnel; security plan; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with personnel security responsibilities; personnel with information security responsibilities].
- Test
- [SELECT FROM: Organizational processes for personnel screening].
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.
