In this episode, Michael Lieberman, Co-founder and CTO of Kusari, walks us through the intersection of open source software and security. We discuss Mike's extensive involvement in OpenSSF projects like SLSA and GUAC, which provide essential frameworks for securing the software development life cycle (SDLC) and managing software supply chains. He explains how these tools help verify software provenance and manage vulnerabilities. Additionally, we explore regulatory concerns such as the Cyber Resilience Act (CRA) and the vital role of the recently released Open SSF Security Baseline (OSPS Baseline) in helping organizations comply with such regulations. Mike also shares insights into the evolution of open source security practices, the importance of reducing complexity for developers, and the potential benefits of orchestrating security similarly to Kubernetes. We conclude with a look at upcoming projects and current pilots aiming to simplify and enhance open source security.   00:00 Introduction and Guest Welcome 00:19 Mike's Background and Role in Open Source 01:35 Exploring SLSA and GUAC Projects 04:57 Cyber Resiliency Act Overview 06:54 OpenSSF Security Baseline 11:29 Encouraging Community Involvement 18:39 Final Thoughts   Resources: OpenSSF's OSPS Baseline GUAC SLSA KubeCon Keynote: Cutting Through the Fog: Clarifying CRA Compliance in C...

Thomas DePierre joins Open Source Security to discuss the central idea from his blog post, "You are all on the hobbyist maintainers turf now," exploring the massive disconnect between the corporate world that consumes open source and the hobbyist community that actually produces it. The conversation reveals this isn't a new problem, but a long-standing reality whose consequences for security, stability, and the future of software we are only now beginning to truly confront.
