What an assessor checks
NIST SP 800-171A breaks 3.12.3 into 1 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- Determine if security controls are monitored on an ongoing basis to ensure the continued effectiveness of those controls.
- Examine
- [SELECT FROM: Security planning policy; organizational procedures addressing security plan development and implementation; procedures addressing security plan reviews and updates; enterprise architecture documentation; security plan; records of security plan reviews and updates; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with security planning and plan implementation responsibilities; personnel with information security responsibilities].
- Test
- [SELECT FROM: Organizational processes for security plan development, review, update, and approval; mechanisms supporting the security plan].
If it is open: POA&M eligibility
Not POA&M-eligible: above the 1-point ceiling · 5 points deducted
Worth 5 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.
