ISO/IEC 27001:2022 — Information Security Management Systems

Technical explanation

The standard requires an organisation to determine its context and ISMS scope, assess and treat information security risks, operate documented controls and processes, evaluate performance and improve the system. Annex A provides a reference set of controls aligned with ISO/IEC 27002.

Business relevance

A functioning ISMS creates accountable, risk-based security governance and can support assurance, procurement, regulatory alignment and independent certification.

Implementation example

A software provider scopes its ISMS, inventories information assets, assesses risks, selects treatments, documents a Statement of Applicability, monitors controls and undergoes independent certification audit.

Limitations and common misconceptions

Certification applies to a defined scope and does not prove that an organisation is breach-proof or that every product is secure. A control checklist without risk context, operation and continual improvement is insufficient.
