Bug Tracker

Any feature requests or bug reports shall go to the todos of sbom.

Primary Source repository

The main source of sbom is on a mountain in central Switzerland. We use distributed version control (git). There is no central hub. Every clone can become a new source for the benefit of all. The preferred public clones of sbom are:

  • on codeberg - a democratic community-driven, non-profit software development platform operated by Codeberg e.V.
  • at sourcehut - a collection of tools useful for software development.

Contributions

Please do not submit "pull requests" (I found no way to disable that "feature" on GitHub). If you like to share small changes under the repositories license please kindly do so by sending a patchset. You can either send such a patchset per email using git send-email or if you are a sourcehut user by selecting "Prepare a patchset" on the summary page of your fork at sourcehut.

Status

Experimental.

Terminology

  • baseline - mandatory elements
  • consume - an SBOM
  • crypto - hashing, signing, and signature validation
  • extension - sets of elements mandatory in addition to baseline
  • fuzz - generate surrogate and poisoned SBOMs
  • merge - an SBOM with other SBOMs or additional information
  • mock - provide optimal testability
  • policy - to apply
  • produce - an SBOM
  • report - anything from produce, transform, and consume
  • rule - executing policies
  • transform - one SBOM into another SBOM

Safety, Security, and Data Protection Considerations

The current implementation SHALL only digest trustworthy data.

Schema validation of JSON and XML formats requires specific measures to
minimize vulnerabilities.

For example: The python xml parser implementation (etree) in
use is presumably vulnerable against some attacks like billion laughs and quadratic blowup.

Plans are to move towards a safer implementation like defusedxml or any other hardened implementation.

The situation is similar for the JSON formats.

In summary and repeating the obvious:

The current implementation SHALL only digest trustworthy data.

Note: The default branch is default.
