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
- Shielding installed at build and then breached by later cable penetrations with no reseal
- No test records, so protection is asserted from design intent rather than measurement
- Protection scoped to the processing equipment while peripherals and cabling carrying the same signal are excluded
