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 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). At the time of publication, ISO/IEC 15045-1:2004 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC. Scope 1.1 Overview This part of ISO/IEC 15045 specifies the minimum functional requirements of a residential gateway (RG) and the documentation to be provided. The standard specifies what a gateway should do in order to deliver services in a suitably safe, secure and future-proof way without being prescriptive. It also gives functional requirements. 1.2 Functional safety This Standard specifies certain safety features where commands sent from remote places to devices on the premises could cause danger to persons or property. While this standard only specifies minimum requirements for the gateway architecture, gateway operation, and associated home systems in terms of safety, it provides an extensive checklist of functional situations that should be treated with the utmost caution and recommends appropriate measures. 1.3 Privacy and security This Standard specifies security measures to ensure the integrity of information that may pass through the residential gateway. A residential gateway operating between the internet and the home creates significant concerns for security to the user. Particular attention is drawn to safety, security and privacy. The attention of the user (consumer, maintainer or application service provider (ASP)) of the gateway is drawn to dangers resulting from unexpected system interoperation, from unauthorised access and from compromise of private user information. RGs that are stated to conform to this standard will be evaluated by the RG manufacturers for potential functional safety and/or security hazards arising from systems integration.
