Supply Chain Risk in cybersecurity refers to the potential threats and vulnerabilities that arise when organizations depend on third-party vendors, suppliers, or partners for goods and services. If a cyberattack compromises one company in the supply chain, it can quickly spread to others connected through shared systems, software, or data. This risk is heightened by the complex, interconnected nature of modern business, making it crucial for organizations to assess and manage the security of all entities in their supply chain to prevent widespread disruption or data breaches.
