What evidence do auditors commonly ask for on IA-12 Identity Proofing (IA-12)?

SSP IA-12 statement stating the identity assurance level targeted and how users are proofed before accounts are created; Identity proofing records for a sample of new accounts showing evidence checked and verifier; Identification and authentication policy; MFA enrolment report for all privileged and remote users; Password policy configuration export from the identity provider; Service account credential vault inventory and rotation logs.

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.

First move

Automate the pull from your Identity provider / directory. Scheduled export of users, roles and MFA state from the directory; access-review completion pulled from the IdP, not a spreadsheet.

Common gaps auditors find

Federation trust relationships not reviewed when partnerships change
MFA exceptions granted indefinitely without compensating controls
Shared accounts authenticate without traceability to individuals
