Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1.

This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

This document was prepared by Technical Committee ISO/TC 292, Security and resilience, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 391, Societal and Citizen Security, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This fourth edition cancels and replaces the third edition ( ISO 22300:2021 ), which has been technically revised.

The main changes are as follows:

removal of terms that are not commonly used across the portfolio of ISO/TC 292 standards and are very specific to particular standards;
definitions for some terms have been modified to be more generic and applicable across the portfolio of ISO/TC 292 standards;
inclusion of new terms and definitions from recent published documents and documents transferred to ISO/TC 292;
the structure of the document has been revised to make the document more concise and user friendly.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html.
