An SBOM (Software Bill of Materials) is a detailed, structured list of all components, libraries, and modules included in a software product. Similar to an ingredient list for food, an SBOM helps organizations understand exactly what is inside their software, including open-source and third-party elements. This transparency is crucial for identifying potential security vulnerabilities, managing software updates, and ensuring compliance with regulations. By maintaining an SBOM, companies can quickly assess risks and respond to security threats more effectively, making it an essential tool in modern cybersecurity and software supply chain management.
