Glossary term

ISO 27001

Also: ISO/IEC 27001, ISMS

International standard for information security management systems. Current version ISO/IEC 27001:2022. Certifiable through accredited bodies. Core framework for ISMS implementation, risk treatment, continuous improvement.

ISO 27001 defines requirements for setting up, implementing, maintaining and continually improving an ISMS. Annex A lists 93 controls across four themes: organisational, people, physical, technological.

Certification by accredited bodies, validity 3 years with annual surveillance audits. Recertification in year three.

In practice

Relationship to NIS2/DORA: ISO 27001 is a strong foundation and covers many minimum measures, but NIS2 and DORA additionally require explicit supply-chain security, concrete reporting deadlines, personal management body liability and sector-specific duties. ISO 27001 is help, not substitute.
