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
- Maintenance vendors lack signed confidentiality and security clauses
- Vendor engineers granted standing access rather than session based access
- Remote maintenance sessions unmonitored after initial authentication
- Maintenance tools not sanitised before removal from secure areas
