For anyone who can attend FOSDEM in Brussels on 5 February 2023, we have a track (“devroom”) on Software Bills of Materials, where a number of SBOM-related topics will be discussed.

 

The Call for Participation is currently open, till 28 November:

https://gist.github.com/zvr/c852b4a560ac2c67885c473034cd4a93

 

Hope to see you there!

Hi Jacob, Shane and all,

 

Thank you for sharing my thought and your interesting response.

Now some of the OpenChain Japan Sub workgroup member started

discussing about SBOM deeply from the perspective how to use SBOM

effectively in the complex supply chains and what is the problem to use it.

We are still in the early stages of discussions, but we will be sharing our

discussions and materials publicly in the future, so could you give us some advice?

And it might be difficult to participate because the language barriers and

time zones, but if you know similar discussion opportunities elsewhere,

please let me know.

I would like to participate as much as possible.

 

Thanks,

-- kobota

This is a great point, and one which I believe has been evolving over time. SAST, DAST, IAST, and RASP outputs similarly all show code analysis at different stages of the software build and distribution process. I would say for storage a Software Artifact Repository is the industry standard for code scanning and will most likely continue for SBOM results, but the combination of results will vary based on organizational policies, procedures, regulators, and other market factors. 

 

If I put my computer forensics hat on, traceability and non-tampered evidence collection are paramount. Having the same piece of information at multiple stages of the software build and distribution process is informative in itself. Combination of the results may harm the overall goal. From a pragmatic perspective this is a significant data storage and analysis challenge.

 

Tying things together, I believe the SBOM consideration material you have made is great and brings light to an important issue. I also believe it fits together remarkably well with the 'SCA tooling evaluation metrics' project mentioned in yesterday's monthly call. Perhaps these stakeholders can work together?

Kobota San has raised an interesting topic for discussion. Attached see slides with an overview.

Summary: there are various different types of SBOM involved in preparing various types of product. For example, Build SBOM, Binary SBOM, Source SBOM.

What is the best way to combine these for final records?

Thoughts and suggestions?
