TL;DR: The 114 ISO 27001 Annex A controls are broken down in a guide that shows how organisations use a Statement of Applicability to decide which controls fit their risks, operations, and compliance scope, according to StrongDM. The real issue is not certification paperwork but whether access, lifecycle, and supplier governance actually map to how identities operate.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “Understanding ISO 27001 Controls [Guide to Annex A]”.
Key questions
Q: How should organisations decide which ISO 27001 Annex A controls apply?
A: Start with risk, legal obligations, operating model, and identity scope.
Q: Why do access controls matter so much in ISO 27001 Annex A?
A: Access controls matter because they connect the standard to actual identity governance.
Q: What breaks when access reviews and offboarding are handled inconsistently?
A: Inconsistent reviews and offboarding create lingering access, compliance gaps, and unnecessary exposure after roles change or people leave.
Practitioner guidance
- Map Annex A.9 to identity lifecycle evidence Link user registration, deregistration, privileged account handling, and access review records to the specific Annex A.9 controls your SoA declares in scope.
- Document SoA decisions with risk rationale Record why each Annex A control is in scope or out of scope, using business context, legal duties, and operational reality rather than generic compliance language.
- Separate privileged access evidence from general access evidence Keep administrator activity, credential handling, and privileged session evidence distinct so auditors can trace control operation without ambiguity.
Bottom line: ISO 27001 Annex A is a governance framework for selecting controls that fit risk, scope, and operating reality, not a fixed checklist.

ISO 27001 Annex A is really an access-governance problem in disguise: the standard spans policies, people, operations, suppliers, and compliance, but the recurring operational hinge is whether identity and privilege are governed well enough to support the selected controls. When access review, provisioning, and offboarding are weak, Annex A becomes harder to evidence even if the broader ISMS looks mature. Practitioners should read the control catalogue as an identity control map first and a certification framework second.
A question worth separating out:
Q: How should organisations balance supplier access with Annex A governance?
A: Organisations should govern supplier access through the same entitlement, logging, and review discipline used for internal identities. Annex A.15 expects supplier relationships to be controlled, monitored, and contractually defined, so third-party access cannot sit outside the identity programme. If it does, accountability and evidence both weaken.
