What an assessor checks
NIST SP 800-171A breaks 3.10.6 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 safeguarding measures for CUI are defined for alternate work sites.
- [b]Determine if safeguarding measures for CUI are enforced for alternate work sites.
- Examine
- [SELECT FROM: Physical and environmental protection policy; procedures addressing alternate work sites for personnel; security plan; list of safeguards required for alternate work sites; assessments of safeguards at alternate work sites; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel approving use of alternate work sites; personnel using alternate work sites; personnel assessing controls at alternate work sites; personnel with information security responsibilities].
- Test
- [SELECT FROM: Organizational processes for security at alternate work sites; mechanisms supporting alternate work sites; safeguards employed at alternate work sites; means of communications between personnel at alternate work sites and security personnel].
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.
