ISO/IEC 27005:2022 — Information security, cybersecurity and privacy protection — Guidance on managing information security risks. This international standard provides guidance for establishing, implementing, maintaining and improving information security risk management processes to support an Information Security Management System (ISMS), including identification, analysis, evaluation, treatment, monitoring and communication of information security risks.

Abstract

ISO/IEC 27005:2022 (4th edition) gives organizations practical guidance for managing risks to the confidentiality, integrity and availability of information. It adapts general risk management principles to the information security context, aligns with ISO/IEC 27001 and ISO 31000, and describes a lifecycle approach covering context setting, risk identification, risk analysis and evaluation, selection and implementation of risk treatments, and ongoing monitoring, review and communication. The standard does not mandate a single assessment method; it supports flexible selection of techniques appropriate to organizational needs.

Scope

Guidance for establishing and operating information security risk management processes applicable to all types and sizes of organizations and all forms of information. The standard covers the full risk management cycle (context, identification, analysis, evaluation, treatment, monitoring and communication) in the specific context of information security and provides advice on selecting or tailoring methods and techniques. It is intended to support implementation of an ISMS based on ISO/IEC 27001, not to replace that standard.

Key topics and requirements

• Establishing the context for information security risk management (business, legal, regulatory and contractual requirements).
• Risk identification: assets, threats, vulnerabilities, and potential impacts on confidentiality, integrity and availability.
• Risk analysis and evaluation: qualitative, quantitative or hybrid approaches; criteria for risk acceptance and prioritization.
• Selection and implementation of risk treatment options (avoidance, transfer, mitigation, acceptance) and mapping to controls.
• Integration with an ISMS (ISO/IEC 27001) and alignment with ISO 31000 risk principles.
• Monitoring, review and continual improvement of risk assessments and treatments; incident learning and change-driven reassessment.
• Roles, responsibilities and communication: involving stakeholders, risk owners and top management.
• Considerations for modern topics: cloud services, supply chain/third-party risks, privacy considerations, ransomware and cyber extortion risks.
• Guidance on selecting and tailoring risk assessment methods rather than prescribing a single technique.

Typical use and users

Used by organizations implementing or improving an ISMS and by professionals responsible for information security risk management: CISOs, information security managers, risk managers, compliance and privacy officers, internal/external auditors, consultants and anyone responsible for selecting and applying security controls based on assessed risk. Also used in training, audits and integration projects involving information security and enterprise risk management.
