What an assessor checks
NIST SP 800-171A breaks 3.7.2 into 4 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- [a]Determine if tools used to conduct system maintenance are controlled.
- [b]Determine if techniques used to conduct system maintenance are controlled.
- [c]Determine if mechanisms used to conduct system maintenance are controlled.
- [d]Determine if personnel used to conduct system maintenance are controlled.
- Examine
- [SELECT FROM: System maintenance policy; procedures addressing system maintenance tools and media; maintenance records; system maintenance tools and associated documentation; maintenance tool inspection records; security plan; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with system maintenance responsibilities; personnel with information security responsibilities].
- Test
- [SELECT FROM: Organizational processes for approving, controlling, and monitoring maintenance tools; mechanisms supporting or implementing approval, control, and monitoring of maintenance tools; organizational processes for inspecting maintenance tools; mechanisms supporting or implementing inspection of maintenance tools; organizational process for inspecting media for malicious code; mechanisms supporting or implementing inspection of media used for maintenance].
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.
