ISO 27001 Annex A 7.1: Physical security perimeters
Quick answer
ISO 27001 Annex A 7.1 (Physical security perimeters) is a physical control. Define and use security perimeters to protect areas that hold information and assets.
What auditors look for
Auditors check that 7.1 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:
- Site plans showing secure areas
- Perimeter controls such as locks and barriers
- Physical risk assessment
How to implement 7.1 in practice
- Base perimeters on what each area holds
- Include server and network rooms
- Reassess when offices change
- Name an owner for 7.1, decide how often it runs and file evidence each time, so the control is audit-ready all year.
Recording 7.1 in the Statement of Applicability
List 7.1 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.
