ISO/IEC 27001:2022 · Physical control
ISO 27001 Annex A 7.11: Supporting utilities
Quick answer
ISO 27001 Annex A 7.11 (Supporting utilities) is a physical control. Protect facilities from power failures and other utility disruptions.
What auditors look for
Auditors check that 7.11 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:
- UPS and generator arrangements
- Maintenance and test records
- Provider resilience attestations
How to implement 7.11 in practice
- Rely on provider attestations for hosted services
- Test UPS units
- Protect network equipment power
- Name an owner for 7.11, decide how often it runs and file evidence each time, so the control is audit-ready all year.
Recording 7.11 in the Statement of Applicability
List 7.11 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.
