where the evidence lives

teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Mostly documents and reviews. Pull the 1 system-held artefact from your Identity provider / directory on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.

Common gaps auditors find

Organization-defined usage conditions such as time of day or location restrictions are documented but not technically enforced on accounts
The specific system accounts subject to usage conditions were never identified, so conditions apply inconsistently across account types
