CSA Group Information technology - Security techniques - Incident investigation principles and processes (Adopted ISO/IEC 27043:2015, first edition, 2015-03-01) CAN/CSA-ISO/IEC 27043:18

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. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). Scope This International Standard provides guidelines based on idealized models for common incident investigation processes across various incident investigation scenarios involving digital evidence. This includes processes from pre-incident preparation through investigation closure, as well as any general advice and caveats on such processes. The guidelines describe processes and principles applicable to various kinds of investigations, including, but not limited to, unauthorized access, data corruption, system crashes, or corporate breaches of information security, as well as any other digital investigation. In summary, this International Standard provides a general overview of all incident investigation principles and processes without prescribing particular details within each of the investigation principles and processes covered in this International Standard. Many other relevant International Standards, where referenced in this International Standard, provide more detailed content of specific investigation principles and processes.
