Ralph Goers commented on LOG4J2-3354:
-------------------------------------
The BOM POM is a convenience for our users to get all the Log4j artifacts into
a dependencyManagement so they are all versioned correctly as part of their
Maven builds.
An SBOM contains the list of dependencies a project has. Read the Links above
for more info.
> Publish an SBOM with Log4j
> --------------------------
>
> Key: LOG4J2-3354
> URL: https://issues.apache.org/jira/browse/LOG4J2-3354
> Project: Log4j 2
> Issue Type: New Feature
> Components: Build
> Reporter: Matt Sicker
> Priority: Major
>
> Log4j should publish a software bill of materials (SBOM) on each release to
> enable end users to more easily discover the versions of both Log4j and
> related dependencies are in use in their software. [Sonatype has a blog post
> explaining what SBOM
> is|https://blog.sonatype.com/what-is-a-software-bill-of-materials], and OWASP
> has a tool called [CycloneDX|https://cyclonedx.org/] which has a [Maven
> plugin|https://github.com/CycloneDX/cyclonedx-maven-plugin] which we could
> potentially use for this.
> Open questions:
> * Do SBOM files get published to Maven Central as additional artifacts?
> * Do we add SBOM files to the source and binary archives?
> * Should the generated SBOM only include required dependencies? This last
> bit is less obvious since we're a library, so the end user can always
> override their full dependency tree when building their app.
> More options for generating an SBOM:
> * [https://github.com/opensbom-generator/spdx-sbom-generator]
> * [https://dependencytrack.org|https://dependencytrack.org/] - integrates
> with CycloneDX (all OWASP tools)
> *
> [https://github.com/AevaOnline/supply-chain-synthesis/blob/main/documents/list-projects.md]
> - larger list of relevant supply chain security tooling
