Recently, "SDV (Software Defined Vehicle)" has been gaining attention. The focus of vehicles is shifting from hardware to software, but it is not practical for companies to develop all the software in-house. As a result, OSS (Open Source Software) has become an essential part of this transition. OSS offers the advantage of utilizing the latest technologies for free, but it also requires compliance with vulnerability management and licensing regulations. Particularly, ensuring the transparency of software distributed within the supply chain is becoming increasingly important, and SBOM (Software Bill of Materials) is gaining attention as a tool for this purpose. In this session, we will introduce organized activities that promote SBOM management and contributions to OSS, including topics related to OSPO (Open Source Program Office).
