ISO/IEC 27001:2022

Overview

ISO/IEC 27001:2022 - Information security, cybersecurity and privacy protection - Information security management systems - Requirements - defines the requirements for establishing, implementing, maintaining and continually improving an Information Security Management System (ISMS). The standard is generic and applicable to all organizations, regardless of type, size or nature, and requires organizations to assess and treat information security risks in a way that is tailored to their needs. The 2022 edition aligns the ISMS structure with the harmonized Annex SL high-level structure and with ISO/IEC 27002:2022 guidance.

Key topics and technical requirements

• Scope and context (Clause 4): Understand the organization, its internal and external context, interested parties, and determine the ISMS scope.
• Leadership and governance (Clause 5): Senior management commitment, information security policy, and defined roles, responsibilities and authorities.
• Planning (Clause 6): Requirements for addressing risks and opportunities, conducting information security risk assessments, and developing risk treatment plans and security objectives.
• Support (Clause 7): Resource allocation, competence, awareness, communication, and documented information controls.
• Operation (Clause 8): Operational planning and control, implementation of risk treatment measures, and execution of security controls.
• Performance evaluation (Clause 9): Monitoring, measurement, internal audit and management review to verify ISMS effectiveness.
• Improvement (Clause 10): Nonconformity handling, corrective actions and continual improvement of the ISMS.
• Annex A (normative): Reference control objectives and information security controls to guide risk treatment (see ISO/IEC 27002 for implementation guidance).

Important: Clauses 4–10 are mandatory for claims of conformity; organizations may not exclude these requirements.

Practical applications and who uses this standard

ISO/IEC 27001:2022 is used to:
