CSA ISO/IEC 27035-2:24

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. For brevity, this Standard will be referred to as "CSA ISO/IEC 27035-2" throughout. This Standard supersedes CAN/CSA-ISO/IEC 27035-2:18 (adopted ISO/IEC 27035-2:2016), Information technology — Security techniques — Information security incident management — Part 2: Guidelines to plan and prepare for incident response. The International Standard was reviewed by the CSA Technical Committee on Cybersecurity under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This document provides guidelines to plan and prepare for incident response and to learn lessons from incident response. The guidelines are based on the "plan and prepare" and "learn lessons" phases of the information security incident management phases model presented in ISO/IEC 27035-1:2023, 5.2 and 5.6. The major points within the "plan and prepare" phase include: — information security incident management policy and commitment of top management; — information security policies, including those relating to risk management, updated at both organizational level and system, service and network levels; — information security incident management plan; — Incident Management Team (IMT) establishment; — establishing relationships and connections with internal and external organizations; — technical and other support (including organizational and operational support); — information security incident management awareness briefings and training. The "learn lessons" phase includes: — identifying areas for improvement; — identifying and making necessary improvements; — Incident Response Team (IRT) evaluation. The guidance given in this document is generic and intended to be applicable to all organizations, regardless of type, size or nature. Organizations can adjust the guidance given in this document according to their type, size and nature of business in relation to the information security risk situation. This document is also applicable to external organizations providing information security incident management services.
