Overview
SIST EN ISO/IEC 27005:2024 (adoption of ISO/IEC 27005:2022 as EN ISO/IEC 27005:2024) provides detailed guidance on managing information security risks to support implementation of an Information Security Management System (ISMS). It helps organizations of any type, size or sector to fulfil ISO/IEC 27001 requirements related to identifying, assessing and treating information security risks, with additional emphasis on cybersecurity and privacy protection.
Key topics and technical coverage
This guidance covers the full information security risk management lifecycle and related ISMS processes, including:
- Risk management process and cycles - principles for establishing iterative risk management activities.
- Context establishment - organizational considerations, stakeholder requirements and risk criteria.
- Risk assessment - identification, description and ownership of information security risks.
- Risk analysis: assessing potential consequences and likelihood to determine risk levels.
- Risk evaluation: comparing results against risk acceptance criteria and prioritizing risks.
- Risk treatment - selecting treatment options, determining and implementing controls, and documenting a risk treatment plan.
- Controls alignment - comparing selected controls with ISO/IEC 27001:2022 Annex A and producing a Statement of Applicability.
- Operation and monitoring - performing assessments and treatments, documented information, communication, monitoring, management review, corrective action and continual improvement.
- Practical techniques - Annex A provides examples of techniques to support risk assessment activities.
- Definitions, normative references and structured guidance to choose appropriate methods and criteria.
