Supply chain security is the part of supply chain management that focuses on the risk management of external suppliers, vendors, logistics and transportation. Its goal is to identify, analyze and mitigate the risks inherent in working with other organizations as part of a supply chain. Supply chain security involves both physical security relating to products and cybersecurity for software and services.
Because supply chains can vary greatly from group to group, and many different organizations may be involved, there is no single set of established supply chain security guidelines or best practices. A complete supply chain security strategy requires following risk management principles and cyberdefense in depth.
