What an assessor checks
NIST SP 800-171A breaks 3.1.7 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 privileged functions are defined.
- [b]Determine if non-privileged users are defined.
- [c]Determine if non-privileged users are prevented from executing privileged functions.
- [d]Determine if the execution of privileged functions is captured in audit logs.
- Examine
- [SELECT FROM: Access control policy; procedures addressing least privilege; security plan; system design documentation; list of privileged functions and associated user account assignments; system configuration settings and associated documentation; system audit logs and records; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with responsibilities for defining least privileges necessary to accomplish specified tasks; personnel with information security responsibilities; system developers].
- Test
- [SELECT FROM: Mechanisms implementing least privilege functions for non-privileged users; mechanisms auditing the execution of privileged functions].
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.
