First move
Mostly documents and reviews. Pull the 1 system-held artefact from your Ticketing / ITSM 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
- 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
