First move
Start with the 2 of 5 artefacts that already live in a system (Identity provider / directory); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- Multi factor authentication enforced on the main access route while legacy access paths and application programming interfaces bypass it
- Boundary defined by network only, missing identity based access from anywhere as the actual boundary
- Rules permitting broad external access retained from an earlier configuration with no review
- Attack attempts logged with no monitoring and no response defined
