Disable identifiers after a defined period of inactivity.

Assessment objectives

Assessors don’t evaluate the requirement as one sentence; they walk these objectives one by one. Each must be met for the requirement to score.

  1. 3.5.6[a]a period of inactivity after which an identifier is disabled is defined.
  2. 3.5.6[b]identifiers are disabled after the defined period of inactivity.

Inside Valontir, this requirement carries a full plain-English guide: what it asks in normal words, what good looks like in a small shop, the evidence an assessor accepts, the common gaps that cost points, and a plain reading of every assessment objective shown above. See it in a demo.
