1. WHAT IS ISO/IEC 27001 CERTIFICATION?
ISO/IEC 27001 is an information security management system (ISMS) for organizations that process data from customers, stakeholders, or even data within the organization.
ISMS secures information in all forms. A robust and effective ISMS system maintains high security standards and is designed to protect against cyber attacks. ISMS focuses on maintaining the security of an organization's data assets. Data loss, unauthorized access or breach are threats that an ISMS can handle.
ISO/IEC 27001 covers risk assessment, organizational structure assessment, information classification, access control, implementation of various information security policies, physical and technical protection measures . It also implies monitoring and reporting guidelines.
With leading global standards like ISO/IEC 27001, ISO/IEC 27001 certified organizations can protect their assets and improve their ISMS.
2. Structure of ISO/IEC 27001:2022
The current edition is ISO/IEC 27001:2022, published in October 2022, together with Amendment 1:2024, which requires organizations to consider climate change when determining their context. The standard has two parts:
Clauses 0–3: introduction, scope, normative references, and terms and definitions. These clauses contain no auditable requirements.
Clauses 4–10: the mandatory requirements for an information security management system (ISMS):
Clause 4 – Context of the organization
Clause 5 – Leadership
Clause 6 – Planning (including information security risk assessment and treatment)
Clause 7 – Support
Clause 8 – Operation
Clause 9 – Performance evaluation
Clause 10 – Improvement
Annex A lists 93 controls in four themes:
| Theme | Number of controls |
|---|---|
| Organizational | 37 |
| People | 8 |
| Physical | 14 |
| Technological | 34 |
The organization must compare its risk treatment controls against all of Annex A and prepare a Statement of Applicability (SoA) stating which controls are applied, which are excluded and why. Annex A is therefore not an "optional" list: not every control has to be implemented, but every control must be considered and justified.
Compared with the 2013 edition (114 controls in 14 domains), the 2022 edition reorganizes the controls into 93 controls in four themes and adds new ones such as threat intelligence, information security for the use of cloud services, and ICT readiness for business continuity. The transition period for moving certificates from the 2013 edition to the 2022 edition ended on 31 October 2025.
