CSA ISO/IEC TR 5891:25

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. For brevity, this Standard will be referred to as "CSA ISO/IEC TR 5891" throughout. The International Standard was reviewed by the CSA Technical Committee on Cybersecurity under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology Systems and deemed acceptable for use in Canada. 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 surveys and summarizes the existing hardware monitoring methods, including research efforts and industrial applications. The explored monitoring technologies are classified by applied area, carrier type, target entity, objective pattern, and method of deployment. Moreover, this document summarizes the possible ways of utilizing monitoring technologies for hardware security assessment with some existing state-of-the-art security assessment approaches. The hardware mentioned in this document refers only to the core processing hardware, such as the central processing unit (CPU), microcontroller unit (MCU), and system on a chip (SoC), in the von Neumann system and does not include single-input or single-output devices such as memory or displays. The hardware monitoring technology discussed in this document has the following considerations and restrictions: — the monitored target is for the post-silicon phase, not for the design-house phase (e.g. an RTL or netlist design); — monitoring is only applied to the runtime system.
