SPRS weight: 1; 1 point deducted from 110 when not implemented.

Assessment objectives: 2; From NIST SP 800-171A, each one a “determine if” an assessor answers.

What an assessor checks

NIST SP 800-171A breaks 3.1.6 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 nonsecurity functions are identified.
[b]Determine if users are required to use non-privileged accounts or roles when accessing nonsecurity functions.

Examine: [SELECT FROM: Access control policy; procedures addressing least privilege; security plan; list of system-generated security functions assigned to system accounts or roles; 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 organizational tasks; personnel with information security responsibilities; system or network administrators].
Test: [SELECT FROM: Mechanisms implementing least privilege functions].

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.

No direct mapping.
