First move
This control is evidenced by people and documents, not systems. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date. Do not try to automate it.
Common gaps auditors find
- Temporary artefacts of one customer's processing persisting on shared infrastructure after the task ends
- Cleanup jobs failing silently with no verification step to catch it
- Procedure covering application temp directories while queues, caches and export staging go unmanaged
- Retention period defined without any check that deletion happened
- Customer data in debug and diagnostic files excluded because they are not seen as processing output
