What an assessor checks
NIST SP 800-171A breaks 3.7.5 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 multifactor authentication is required to establish nonlocal maintenance sessions via external network connections.
- [b]Determine if nonlocal maintenance sessions established via external network connections are terminated when nonlocal maintenance is complete.
- Examine
- [SELECT FROM: System maintenance policy; procedures addressing nonlocal system maintenance; security plan; system design documentation; system configuration settings and associated documentation; maintenance records; diagnostic records; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with system maintenance responsibilities; personnel with information security responsibilities; system or network administrators].
- Test
- [select from: Organizational processes for managing nonlocal maintenance; mechanisms implementing, supporting, and managing nonlocal maintenance; mechanisms for strong authentication of nonlocal maintenance diagnostic sessions; mechanisms for terminating nonlocal maintenance sessions and network connections].
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.
