ISO/IEC 27001:2022 – Information Security Management

What is ISO 27001 information security management?

What is an ISMS?

An ISMS takes a systematic approach to securing the CIA (confidentiality, integrity and availability) of corporate information assets.

An ISO 27001 ISMS consists of organisational, people, physical and technological controls, selected on the basis of regular risk assessments.

Its technology- and vendor-neutral approach makes it suitable for all organisations, whatever their size, complexity, sector or location.

ISO 27001 has changed

ISO/IEC 27001:2022 – the newest version of ISO 27001 – was published in October 2022. As of 30 April 2024, certification bodies can no longer offer (re)certification to the 2013 edition of the Standard.

ISO 27001 benefits

ISO 27001 is one of the most popular information security standards in existence. Independent accredited certification to the Standard is recognised worldwide. The number of certifications has grown by more than 450% in the past ten years.

Implementing the Standard helps you meet the requirements of laws such as the UK and EU GDPR (General Data Protection Regulation) and the NIS (Network and Information Systems) Regulations. It also helps reduce the costs associated with data breaches.

How to achieve ISO 27001 compliance

Implementing an ISMS involves the following:

• Scoping the project.
• Securing management commitment and adequate resources.
• Identifying interested parties and applicable legal and contractual requirements.
• Conducting a risk assessment.
• Selecting and implementing the required controls.
• Developing internal competence to manage the project.
• Developing the appropriate documentation.
• Conducting staff awareness training.
• Continually measuring, monitoring, reviewing and auditing the ISMS.
• Implementing the necessary corrective and preventive actions.

ISO 27001 and risk management

Risk management forms the cornerstone of an ISMS. All ISMS projects rely on regular information security risk assessments to determine which security controls to implement and maintain.

The Standard defines its requirements for the risk management process, including risk assessment and treatment, in Clause 6.1.

ISO 27001 clauses and controls

ISO 27001:2022 has ten management system clauses. Together with Annex A, which lists the 93 information security controls from ISO 27002:2022, they support the implementation and maintenance of an ISMS.

1. Scope 
2. Normative references 
3. Terms and definitions 
4. Context of the organization
5. Leadership

6. Planning 
7. Support 
8. Operation 
9. Performance evaluation
10. Improvement

Although the 2022 version of the Standard has fewer controls than the 2013 version, this is because many controls have been merged rather than removed. ISO 27002:2022 also introduces 11 new controls.

The 93 controls are grouped into four themes:

1. Organisational (37 controls)
2. People (8 controls)

3. Physical (14 controls)
4. Technological (34 controls)

ISO 27001 doesn’t require all 93 to be implemented. Instead, your risk assessment should define which controls are required, and you should justify why other controls are excluded.

Demonstrating GDPR compliance with ISO 27001 and ISO 27701

Like all ISO management system standards, ISO 27001 follows Annex SL. This common high-level structure makes implementing integrated management systems that conform to multiple standards easier.

For instance, an ISO 22301-compliant BCMS (business continuity management system) could share components with an ISO 27001-compliant ISMS.

ISO 27701 is an extension to ISO 27001, expanding its requirements to cover privacy management. This includes the processing of personal data or PII (personally identifiable information).

Implementing an integrated ISMS and ISO 27701-compliant PIMS (privacy information management system) will help you meet the GDPR’s requirements for managing, processing and protecting personal data.
