What is ISO/IEC 27002?

ISO/IEC 27002:2022 Information technology — Security techniques — Code of practice for information security controls

ISO/IEC 27002:2022 serves as a guidance document, providing best-practice guidance on applying the controls listed in Annex A of ISO 27001. This includes the selection, implementation and management of controls taking into consideration the organization’s information security risk. This document should be read and used alongside ISO 27001. The suggested controls listed in the standard are intended to address specific issues identified during a formal risk assessment. The standard is also intended to provide a guide for the development of security standards and effective security management practices.

ISO 27002:2022 was created to be used by organizations that intend to:

  • select controls within the process of implementing an ISMS based on ISO 27001
  • implement accepted information security controls
  • develop their own information security management guidelines

What is the difference between ISO/IEC 27002 and ISO 27001?

ISO/IEC 27001 provides the specifications for an ISMS. This includes requirements for the risk management process that your organization will choose depending on what is appropriate for the risks your organization faces.

ISO 27002 serves as a guidance document, providing best-practice guidance on applying the controls listed in Annex A of ISO 27001. It is a supporting document of ISO 27001 and should be used alongside it.

ISO 27001 is the only standard within the ISO 27000 series of information security standards for which organizations can achieve certification.
