Compliance Framework

ISO/IEC 27001:2022 — Information Security Management

The international standard for building, maintaining and certifying an Information Security Management System. The benchmark for demonstrating security maturity to clients, regulators and insurers.

Overview

What is ISO 27001?

ISO/IEC 27001:2022 is the international standard for Information Security Management Systems (ISMS). It provides a systematic framework for managing sensitive information, ensuring confidentiality, integrity and availability through a risk-based approach. It is widely recognised as the gold standard for information security governance worldwide.

The standard is built around Clauses 4–10, which define the mandatory requirements for establishing, implementing, maintaining and continually improving an ISMS. Annex A provides 93 reference controls across four themes: organisational, people, physical and technological.

Who needs ISO 27001?

Any organisation that handles sensitive data — whether customer information, intellectual property, financial records or health data. It is increasingly required by enterprise clients, government procurement, insurers and investors as a minimum bar for security assurance. In Australia, ISO 27001 is often used alongside the Essential Eight and APRA CPS 234 to demonstrate a mature security posture.

The 7 mandatory clauses

Clauses 4–10 form the auditable core of ISO 27001. Each clause must be satisfied to achieve certification.

4

Context of the Organisation

Define the scope of your ISMS, identify internal and external factors, and understand stakeholder requirements.

5

Leadership

Senior management must demonstrate commitment, establish an information security policy, and assign roles and responsibilities.

6

Planning

Conduct risk assessments, define risk treatment plans, and produce a Statement of Applicability mapping Annex A controls.

7

Support

Ensure adequate resources, competence, awareness, communication and documented information to support the ISMS.

8

Operation

Implement the risk treatment plan, execute operational controls, and conduct regular risk assessments.

9

Performance Evaluation

Monitor, measure and evaluate ISMS effectiveness. Conduct internal audits and management reviews.

10

Improvement

Address nonconformities, implement corrective actions, and drive continual improvement of the ISMS.

A

Annex A Controls

93 reference controls across organisational, people, physical and technological themes. Select based on your risk assessment.

The 2022 update — what changed

The 2022 revision reorganised Annex A from 114 controls in 14 domains to 93 controls in 4 themes, added 11 new controls (including threat intelligence, data masking and secure coding), and strengthened requirements around change planning, stakeholder needs and performance evaluation. Organisations must have completed migration from the 2013 version by October 2025.
