A supply chain is the entire network of organizations, people, activities, information, and resources involved in creating and delivering a product or service to the end user. It includes everything from sourcing raw materials to manufacturing, transportation, warehousing, and distribution. In cybersecurity, supply chains are important because vulnerabilities or attacks can occur at any point in this network, potentially compromising the final product or service. Managing supply chain security is crucial to protect businesses from disruptions, data breaches, or malicious tampering.
