First move
Start with the 4 of 15 artefacts that already live in a system (SIEM / log platform); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- testing conducted without documented management signoff
- failure to assess and document risk before testing
- lack of communication to operations leading to unexpected outages
- no post-test review or lessons learned captured
