An SBOM is used to answer questions about what is inside your software: which components have known vulnerabilities, which products are affected by a new flaw, which licences apply, what changed between releases, and what you can tell a customer. It earns its keep when it is current, complete and machine readable.
The six uses
| Use | Question | What the SBOM must contain |
|---|---|---|
| Vulnerability matching | Which components have known flaws? | Exact versions and machine matchable identifiers |
| Incident scoping | Are we affected by this new advisory? | Transitive components across all products |
| Licence review | Can we ship this? | Licence data per component |
| Release diffing | What changed since the last release? | Stable identifiers across versions |
| Customer and auditor requests | What can we show? | A standard format and a clear description of what it covers |
| Due diligence | What are we buying or merging? | Complete inventory with source and supplier where known |
Use one: vulnerability matching
A scanner compares component versions in the SBOM with advisory data, for example from the OSV database, which can be queried by package and version. The match is only as good as the version and identifier in the file.
Use two: incident scoping
When a new flaw is announced, you search stored SBOMs, not repositories. A search takes minutes if the data is current and days if it lives in people's heads.
Use three: licence review
Standards such as CycloneDX and SPDX have fields for licences. Missing licence data is common, so check coverage before you rely on it.
Use four: release diffing
Compare two SBOMs and you see added, removed and upgraded components. That makes change review and unexpected additions easier to spot.
Use five: customer and auditor requests
A standard format file answers many questionnaire items at once. Be clear what it describes: source, build or deployed software, and which date.
Use six: due diligence
Buyers and investors want to know what open source and third party code a product contains. An SBOM gives a starting point, to be checked against the code.
What makes an SBOM useless
- Version ranges instead of exact versions.
- No transitive dependencies.
- No identifiers that machines can match.
- Generated once and never refreshed.
- No statement of what it covers.
Quick check
Is an SBOM a security control?
It is an input to controls. By itself it does nothing. Used for matching, scoping and diffing, it makes real controls possible.
How current must it be?
As current as the software it describes. Generate it in every build and keep it with the release.
Where Safeguard fits
Safeguard's SBOM and dependency scanning generates and uses SBOMs for matching and monitoring. The free scan takes a project and shows the result.
