ISO 27001 Documentation Essentials

Clear, well-maintained documentation is the foundation of ISO 27001 compliance.
Auditors will expect to see that your ISMS is not only effective but also fully documented and traceable.

Mandatory documentation includes:

• Information security policy

• Scope of the ISMS

• Statement of Applicability (SoA)

• Risk assessment and treatment methodology

• Risk treatment plan

• Evidence of control operation

• Internal audit and management review records

• Corrective action records

Additionally, you should maintain documented procedures for key security processes, including access control, incident response, and business continuity.

Keeping documentation current is critical.
Stale or inconsistent documentation is a common cause of audit findings.
