Max Mehl and Sebastian Wolf discuss the importance of Software Bills of Materials (SBOMs), including license compliance, export control restrictions, and risk management. They highlight the challenges faced by organizations in implementing SBOMs and the growing significance due to legal requirements and security reasons. The difference between SBOM and SPOD is also explored. Additionally, the podcast covers approaches to SBOM management, including proprietary solutions and open-source tools.
Software Bills of Materials (SBOMs) are crucial for managing software components, ensuring legal compliance and addressing security vulnerabilities.
Open-source components play a vital role in SBOMs, helping organizations comply with licenses, improve open-source management, and guide investment decisions.

The Importance of S-Bombs in Managing Software Components
S-Bombs, or software bill of materials, are crucial for managing software components, particularly open-source components, in various products and services. By analyzing and clearing these components, organizations can ensure legal compliance and address security vulnerabilities. While S-Bombs are not a universal solution, they serve as a means to an end, providing insights into supply chain management and better open-source management. Collaboration and communication among stakeholders, including engineers and different parts of the organization, are essential for implementing S-Bombs effectively. Joining discussions in forums like the Open Source Security Foundation, SPDX, and CycloneDX can contribute to the development of S-Bombs standards and sharing best practices.
The Relevance of Open Source in S-Bombs
Open-source components are widely used in software products, making them integral to S-Bombs. Organizations must handle open source component usages, ensuring compliance with legal requirements, giving credit to authors, and managing licenses. Open-source tools and services facilitate S-Bombs creation and management. For instance, the open-source software revenue toolkit and other community offerings provide support in generating S-Bombs. S-Bombs aid not only in complying with licenses but also improve open-source management. They help identify the most used open-source components, allocate resources effectively, and guide investment decisions. Open source contributes to S-Bombs by providing solutions to challenges and fostering community engagement.
Challenges and Discussions in S-Bombs Implementation
Implementing S-Bombs presents challenges, such as the diverse requirements and unique implementation for each organization. Standardization efforts are ongoing, with initiatives like SPDX and CycloneDX providing specifications for S-Bombs. However, the main challenge lies in how organizations can integrate S-Bombs into their software development lifecycle. It requires defining minimal requirements based on specific needs, avoiding bloating standards with unnecessary details. Discussions and collaboration are essential to address real-life experiences, adapt S-Bomb generation and consumption, and tailor solutions to individual organizations' processes. Engaging with communities in organizations like the Open Source Security Foundation enables collaboration and convergence towards better S-Bombs practices and standards.
S-Bombs at SAP and Deutsche Bahn
SAP and Deutsche Bahn have been actively working on S-Bombs management. SAP has a history of managing S-Bombs, combining proprietary and open-source solutions like Eclipse Software 360. SAP is focused on unifying S-Bomb solutions to ensure compliance with legal requirements and address license, export control, and security vulnerability management. At Deutsche Bahn, S-Bomb management is interdisciplinary, involving security engineers, open-source specialists, and project managers. Implementing S-Bombs varies across organizations, and the challenge lies in standardizing processes, workflows, and tools. Deutsche Bahn faces unique challenges in managing software, hardware, and operations components. The journey for effective S-Bombs implementation and management is ongoing.
In this episode, our host Karsten Hohage talks to Max Mehl and Sebastian Wolf about Software Bills of Materials or SBOMs. An SBOM is a detailed record of all components within a software application, including open-source libraries, third-party dependencies and licenses. Max and Sebastian discuss the importance of SBOMs as well as some challenges and unanswered questions of the state of the art. They also speak with Karsten about SBOMs within SAP and Deutsche Bahn and the importance of SBOMs when it comes to open source.

Max Mehl
Max has been committed to free and open-source software for many years. He is responsible for all aspects of open source at DB Systel. In this role, he supports Deutsche Bahn in using and contributing to open source professionally. He previously worked for the Free Software Foundation Europe (FSFE), where he coordinated initiatives such as REUSE and “Public Money? Public Code!”. He is a board member of FSFE and F-Droid and is involved in several projects as a maintainer.
Sebastian is a development architect and has worked for the SAP OSPO since the beginning of 2020. He first joined SAP in 2003 as a student and has since worked in several development positions at, for example, SAP SRM, ABAP Development Tools, the SAP Community Network, and Central Architecture. He was engaged at the Corona-Warn-App project as a community manager from the very beginning and is now coordinating open-source consumption topics in the SAP OSPO.
