First move
Start with the 1 of 4 artefacts that already live in a system (Cloud console / configuration management); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- customer-managed keys applied everywhere with no rationale, adding operational risk
- requirement asserted but the store still uses platform-managed keys
- no tested procedure for key revocation
