DefinitionThe Cyber/Physical Security Framework (サイバー・フィジカル・セキュリティ対策フレームワーク, CPSF) is a framework compiled by METI to secure the entire supply chain (the chain of companies from sourcing raw materials to delivering products) in an industrial society where online cyberspace and the real-world physical space are linked.
ExplanationIt views industrial society in three layers: links between companies, links between physical space and cyberspace through things, and links of data within cyberspace. For each layer it sorts out what must be protected and the risks involved, and it presents an approach to measures that any industry can use.
AnalogyIt is like a safety plan for a railway network. Hazards are listed for each kind of link: through services between companies, the connection between tracks and the operating system, and the exchange of timetable data.
Memory hookCPSF stands for Cyber/Physical Security Framework. "Physical" means something you can touch, and refers to the real-world side such as factory machines and sensors.
