CAN/CSA-ISO/IEC 15816:04 (R2022)

CSA Preface

Standards development within the Information Technology sector is harmonized with internationalfstandards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) 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).

This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada.

Scope

The scope of this Recommendation | International Standard is:

a) the definition of guidelines for specifying the abstract syntax of generic and specific Security Information Objects (SIOs) for Access Control;

b) the specification of generic SIOs for Access Control;

c) the specification of specific SIOs for Access Control.

The scope of this Recommendation | International Standard covers only the statics of SIOs through syntactic definitions in terms of ASN.1 descriptions and additional semantic explanations. It does not cover the dynamics of SIOs, for example rules relating to their creation and deletion. The dynamics of SIOs are a local implementation issue.
