ISO 27001 Annex A 7.12: Cabling security
Quick answer
ISO 27001 Annex A 7.12 (Cabling security) is a physical control. Protect power and data cables from interception, interference and damage.
What auditors look for
Auditors check that 7.12 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:
- Cabling layout
- Protected cable routes
- Inspection records
How to implement 7.12 in practice
- Restrict access to network closets
- Label and document cabling
- Avoid exposed network ports in public areas
- Name an owner for 7.12, decide how often it runs and file evidence each time, so the control is audit-ready all year.
Recording 7.12 in the Statement of Applicability
List 7.12 with whether it applies, the reason (usually the risks it treats or a legal or contractual requirement), its implementation status and where the evidence lives. If you exclude it, explain why none of your risks or obligations require it.
