An SBOM, or Software Bill of Materials, provides a clear and accessible reference for all open source software components in your software. This isn’t just a central location to understand how information and dependencies flow within your architecture, it is crucial to proactively address cybersecurity risks in real-time. While simple to understand as an operational mandate, technical implementation has surfaced fascinating differences in the ways we deliver software from cases like BuildRoot to Cloud Computing Machine Learning. This talk will give you a better understanding of the why and how behind SBOMs for different architectures, resources to automate your SBOMs and this how verified metadata is crucial to the secure globalisation of Open Source.
