Definition
Supply Chain Security refers to the practice of safeguarding the integrity and security of systems, software, and hardware throughout their entire lifecycle, from development and manufacturing to deployment and maintenance. It involves identifying and mitigating risks associated with third-party components, suppliers, and vendors that contribute to the technology ecosystem. This approach is crucial for preventing malicious code injection, unauthorized access, and supply chain attacks that could compromise sensitive data or disrupt operations. For instance, ensuring that all software libraries used in application development are vetted for vulnerabilities is a key supply chain security measure. Unlike traditional security that focuses on the perimeter, supply chain security extends protection to the origins and dependencies of technology. This concept is frequently tested on cybersecurity certifications like CompTIA Security+, CySA+, and CISSP.
