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
- Password complexity enforced but reuse not blocked across systems
- Federation trust relationships not reviewed when partnerships change
- MFA exceptions granted indefinitely without compensating controls
- Shared accounts authenticate without traceability to individuals
Do this for your whole sheet
Paste the rows you run your controls from and get this mapping for every control at once, with the periodic-review ones flagged and a first move per row. No account for the first run.
