Where the definition came fromawaiting curator confirmation

generalized from a web lookup of the quoted expression at proposal time Verdict: term of art.

A definition generalized from search results is a draft to react to, not provenance. Confirm it against an authority document before this term is verified.

A web lookup ran when this term was proposed

A policy threshold — either a duration or a described condition — that an organization defines to represent a session or period during which a user is not expected to interact with a system. It functions as the trigger criterion in session-management controls: NIST SP 800-53 AC-2(5) requires that "users log out when [Assignment: organization-defined time period of expected inactivity or description of when to log out]." The concept is intentionally broader than a simple countdown timer: the organization may supply either an "organization-defined time-period of expected inactivity" or a "description of when to log out," accommodating both quantitative thresholds and qualitative, scenario-based conditions. The control is behavior- or policy-based and requires users to take physical action to log out when they are expecting inactivity longer than the defined period.

Advisory only. A term this product ships is defined by an authority document, not by a search result.

Proposed during multiword review of this document in the CKI mapping queue.
