What an assessor checks
NIST SP 800-171A breaks 3.1.17 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 wireless access to the system is protected using encryption.
- [b]Determine if wireless access to the system is protected using authentication.
- Examine
- [SELECT FROM: Access control policy; system design documentation; procedures addressing wireless implementation and usage (including restrictions); security plan; system configuration settings and associated documentation; system audit logs and records; other relevant documents or records].
- Interview
- [SELECT FROM: System or network administrators; personnel with information security responsibilities; system developers].
- Test
- [SELECT FROM: Mechanisms implementing wireless access protections to the system].
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.
