SBOMs, as defined by US Executive Order 14028, list software components and their supply chain relationships, aiding in risk assessment and compliance with regulations.

Software transparency involves more than just SBOMs; it encompasses visibility into design elements, security features, testing results, and provenance. This transparency supports trustworthiness and may be mandated by regulations, such as the US FDA’s Section 524(b). Understanding transparency’s benefits is crucial for producers, who create transparency information, and choosers, who use it to evaluate software.

Software transparency is crucial for organizations as it aids in decision-making regarding software risk. Depending on an organization’s role, it may produce, choose, or operate software using Software Bill of Materials (SBOMs). SBOMs help monitor vulnerabilities, understand software components, manage dependencies, and ensure compliance with licenses and regulations.

For software producers, SBOMs are used to monitor component vulnerabilities, promote code reuse, and comply with licenses. Producers must determine how customers will access this information, which can be through various mechanisms such as customer portals or third-party services.

Choosers of software use SBOMs to identify vulnerabilities, verify sourcing, and ensure compliance. Procurement teams may leverage transparency as a negotiating point due to the potential risks associated with unknowns.

Operators utilize SBOMs to evaluate components, identify vulnerabilities, and make informed risk-based decisions. However, tools to consume SBOMs for operational purposes are limited. The Enduring Security Framework’s guidelines help organizations use SBOMs effectively, though detailed Vulnerability Exploitability eXchange (VEX) information is often required for automated decision-making.

VEX, a security advisory indicating vulnerability status, complements SBOMs in vulnerability management. Organizations focus on known exploitable vulnerabilities to prioritize risks effectively.

SBOMs, established by the NTIA and CISA, are essential for component transparency. They are machine-readable files listing software components and their versions. SBOMs can be generated at various stages, such as prebuild or postbuild, using specialized tools. Sharing SBOMs is vital for transparency, but some organizations treat them as intellectual property, sharing them under restricted conditions.

Three main SBOM formats exist: CycloneDX, SPDX, and SWID. CycloneDX and SPDX are frequently updated to align with evolving use cases. Organizations often use both formats, and tools maintain compatibility with them.

SBOMs include elements like author, timestamp, supplier name, component name, and version. While not all elements are required, they provide a comprehensive view of software components and dependencies.

Despite their benefits, SBOMs have limitations. Software naming inconsistencies, incomplete SBOMs, and challenges in backporting patches can affect their accuracy.
