First move
Mostly documents and reviews. Pull the 1 system-held artefact from your SIEM / log platform 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
- Critical patches deployed beyond the policy SLA without exception
- EDR coverage gaps on legacy operating systems
- Anti malware signatures not updated on isolated network segments
