In response to the growing reliance on connected medical devices in today's Internet of Things (IoT) landscape, the FDA has introduced new cybersecurity requirements that went into effect March 29, 2023. These requirements aim to address the potential risks associated with increased connectivity in medical devices. One important aspect of these requirements is the implementation of a Cybersecurity Bill of Materials (CBOM).

The CBOM mandates that medical device manufacturers provide a comprehensive list of software and hardware components used in their devices, including third-party software and open-source components. This list, known as the Software Bill of Materials (SBOM), plays a crucial role in ensuring the cybersecurity of these devices. It enables manufacturers and healthcare providers to assess the potential risks posed by the software components and meet the regulatory requirements set forth by the FDA.

By developing and maintaining an accurate SBOM, manufacturers can demonstrate compliance with the FDA's cybersecurity requirements and prioritize the safety and security of their connected medical devices. The SBOM goes beyond a mere regulatory obligation; it is a foundational tool for safeguarding patient health and data in our increasingly interconnected and software-driven healthcare environment.

The FDA's emphasis on the SBOM underscores the need for a structured approach in its development. This ensures all relevant software components are accounted for and thoroughly evaluated for potential vulnerabilities. By adhering to this approach, manufacturers can comply with regulatory standards and uphold the highest level of cybersecurity in their medical devices.

Software Composition Analysis (SCA) is indispensable in developing and maintaining medical devices in today's cyber-centric world. By effectively identifying and managing the risks associated with software components, manufacturers can ensure compliance with FDA's cybersecurity regulations and safeguard the reliability and security of their medical devices.

However, the benefits of SCA extend beyond the medical device industry. In a rapidly evolving software landscape, organizations face the challenge of managing an ever-increasing amount of open-source code.

The relationship between Software Bill of Materials (SBOMs) and Software Package Data Exchange (SPDX) is crucial in ensuring software integrity and compliance within the software supply chain. SBOMs and SPDX are standardized formats for documenting and managing software components but have different focuses and objectives.

SBOMs, as outlined by the National Telecommunications and Information Administration (NTIA), provide a minimum set of elements necessary to describe the components and dependencies of a software application. In addition to the NTIA's requirements, the Food and Drug Administration (FDA) mandates specific additional elements for SBOMs in the context of medical device software. These additional elements include support level, support end date, and known security vulnerabilities. However, these elements primarily apply to third-party or commercial components utilized within an application, as open source projects generally do not have support levels or support end dates.

On the other hand, SPDX is a standardized format developed by the Linux Foundation to facilitate the exchange of software package information. SPDX focuses on providing a comprehensive way to track and document licensing information and copyright attributions within software components. It enables organizations to understand the licenses associated with the different software packages they use and ensures compliance with open source license obligations.

While SBOMs and SPDX have different focuses, they are closely related and can work in tandem to enhance software supply chain management. Synopsys, for example, offers an SBOM-as-a-service solution that not only delivers a complete and accurate SBOM but also generates it in standard formats such as SPDX and CDX. This allows organizations to meet the FDA's SBOM requirements and enables efficient exchange of software package information using SPDX.
