ISO 27001 Annex A 8.34: Protection of information systems during audit testing
Quick answer
ISO 27001 Annex A 8.34 (Protection of information systems during audit testing) is a technological control. Plan and agree audit tests and other assurance activities on operational systems to limit disruption.
What auditors look for
Auditors check that 8.34 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:
- Audit test plans
- Read-only access for auditors
- Approvals for testing on live systems
How to implement 8.34 in practice
- Agree scope and timing with system owners
- Give auditors read-only access
- Remove audit access afterwards
- Name an owner for 8.34, decide how often it runs and file evidence each time, so the control is audit-ready all year.
Recording 8.34 in the Statement of Applicability
List 8.34 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.
