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 3.1.11 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 conditions requiring a user session to terminate are defined.
[b]Determine if a user session is automatically terminated after any of the defined conditions occur.

Examine: [SELECT FROM: Access control policy; procedures addressing session termination; system design documentation; security plan; system configuration settings and associated documentation; list of conditions or trigger events requiring session disconnect; 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 user session termination].

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.
