T/SIA 031.3-2021 System Safety Engineering: Network Resilience Construction Guide Part 3: Network Resilience Construction Process
Basic Information
Scope
Scope: This part of the standard defines: (1) The concept, methods, and processes of network resilience construction. (2) This part is the third part of the "System Security Engineering - Guide to Network Resilience Construction". (3) This part proposes network resilience construction processes oriented to the system life cycle, which correspond to the technical processes of the system life cycle process. These processes can occur in the requirement analysis, design, production, use, and support phases of the system life cycle, and can be carried out simultaneously or independently of daily operation work. (4) Organizations can select, adapt, or use some or all of the network resilience construction processes described in this part to customize or tailor the network resilience structure of the target system and apply them to technical, operational, and threat environments. (5) This part is used to support system safety engineering, and is used together with the standard GB/T 22032-2021 (ISO/IEC/IEEE 15288-2015, IDT), and serves as a supplement to the standard GB/T 22032-2021 (ISO/IEC/IEEE 15288-2015, IDT), or is developed as an extension of network resilience to guide government departments, public institutions, and enterprises (hereinafter collectively referred to as "organizations") to incorporate network resilience as a feature or attribute of system construction.
