What is a Software Bill of Materials (SBOM)?
An SBOM is a comprehensive list of all the software components, dependencies, and metadata associated with an application. The SBOM functions as the inventory of all the building blocks that make up a software product. With it, organizations can better understand, manage, and secure their applications.
The need for SBOMs is driven by several factors that include:
- Ensuring software transparency
- Managing open-source software and third-party dependencies
- Identifying and mitigating security vulnerabilities
- Complying with legal and regulatory requirements
The Executive Order on Improving the Nation's Cybersecurity was issued by the US government in May 2021, and it highlighted the importance of SBOMs in enhancing the security of the software supply chain.
