Securing the Software Supply Chain: A deep dive into SBOMs and their impact
Introduction
In recent years, the focus on securing the software supply chain has gained momentum. This involves two distinct but related aspects: the commercial relationships between software vendors and clients, and the software dependency relationships among open-source project maintainers and consumers. As reliance on software increases—especially in critical infrastructure—attacks have escalated, making it imperative to seek solutions that enhance transparency and security.
Understanding Software Build Materials (SBOMs)
Software Bill of Materials (SBOMs) are instrumental in addressing the vulnerabilities associated with the software supply chain. As defined, an SBOM serves as a comprehensive list of components within a software package. The American and European governments are actively discussing potential regulations to ensure transparency in how software is built and consumed. The basic premise is that software should provide detailed "ingredient lists," which can enable better risk management and vulnerability disclosures.
The recent interest in SBOMs stems from high-profile attacks targeting software supply chains that have serious consequences for national security and critical infrastructure. With software now integral to many facets of daily life, the implications of software vulnerabilities are far-reaching.
Responsibilities in the SBOM Ecosystem
The responsibility for creating and managing SBOMs is currently diffuse. While there is a growing consensus that software creators should attach SBOMs to their packages, this is not yet required by law, posing challenges for independent contributors and underfunded projects. As more stakeholders become involved in the SBOM process, the expectation for clear communication of vulnerabilities will increase significantly.
However, the complication arises when different vendors have differing levels of resistance toward creating SBOMs. Proprietary software vendors may feel apprehensive about unveiling sensitive information, whereas open-source projects tend to be more forthcoming. The burden to create these documents can be considerable, especially when current tooling does not facilitate seamless integration into the development process.
The European Cyber Resilience Act: Impacts and Concerns
In Europe, the Cyber Resilience Act aims to delineate responsibilities related to software security but has raised concerns among stakeholders in the open-source community. The Act currently lacks differentiation between commercial entities and those in the dependency chain, which could impose undue burdens on open-source maintainers. As it stands, the legislation might threaten the very existence of many open-source projects if they cannot meet stringent requirements for SBOM production.
While discussions persist, both the Linux Foundation Europe and the Eclipse Foundation have raised alarms over the lack of clarity and support for smaller projects that rely on volunteer contributions without revenue streams.
In summary, while SBOMs are essential for enhancing the security of the software supply chain, the current landscape poses challenges for both regulation and practical implementation. The role of software creators, consumers, and policymakers in managing these documents will be critical as the industry navigates these evolving requirements.

FAQ
What are SBOMs?
SBOMs (Software Bills of Materials) are comprehensive lists that describe the components or packages used in building a piece of software.
Why is securing the software supply chain important?
Securing the software supply chain is essential due to the increasing sophistication of cyberattacks that target software vulnerabilities impacting critical infrastructure.
Who is responsible for creating SBOMs?
Currently, there is no specific regulation tying responsibility for SBOM creation. However, there is an increasing expectation for software creators to provide these documents.
How is the Cyber Resilience Act affecting stakeholders?
The Cyber Resilience Act may impose burdens on open-source maintainers by not distinguishing between commercial entities and those that do not generate revenue, raising concerns about the viability of their projects.
What challenges exist in creating SBOMs?
Challenges include a lack of seamless tooling for integration into the development process and resistance from some proprietary vendors wary of sharing sensitive information.
