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).
For brevity, this Standard will be referred to as CSA ISO/IEC 27009 throughout.
This Standard supersedes CAN/CSA-ISO/IEC 27009:18 (adopted ISO/IEC 27009:2016). At the time of publication, ISO/IEC 27009:2020 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
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 specifies the requirements for creating sector-specific standards that extend ISO/IEC 27001, and complement or amend ISO/IEC 27002 to support a specific sector (domain, application area or market).
This document explains how to:
- include requirements in addition to those in ISO/IEC 27001,
- refine or interpret any of the ISO/IEC 27001 requirements,
- include controls in addition to those of ISO/IEC 27001:2013, Annex A and ISO/IEC 27002,
- modify any of the controls of ISO/IEC 27001:2013, Annex A and ISO/IEC 27002,
- add guidance to or modify the guidance of ISO/IEC 27002.
This document specifies that additional or refined requirements do not invalidate the requirements in ISO/IEC 27001.
This document is applicable to those involved in producing sector-specific standards.
