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
- Patch rooms unlocked or holding a key kept above the door frame, defeating the whole control
- Labelling absent or wrong, so patching errors cross security zones without anyone realising
- Cabling documentation frozen at build with years of undocumented changes since
- No inspection, so an unauthorised device or tap in a comms room could sit indefinitely
