Software Bill of Materials (SBOM) for IoMT Software: FDA Compliance Guide
#1
A connected medical device submission may be blocked by the U.S. FDA due to insufficient cybersecurity documentation. A software bill of materials sbom for IoMT software provides a precise, machine-readable list of all software components that are used by connected medical devices.  From open-source libraries to transitive dependencies are mentioned inside the SBOM.
Even one missing, out-of-date, or misidentified component can cause a cybersecurity and compliance issue that could block the submission. The FDA now demands strict security standards from all connected medical devices. Without the exact computer-readable list of each software component and background libraries, getting FDA compliance is impossible.
In this article, you will get a complete idea about how to make your connected medical software FDA-compliant, what is required by FDA Section 524B, how to choose a proper format of SBOM, and how to automate the process of SBOM generation.

Key Takeaways
  • The FDA mandates that manufacturers of IoMT devices must have a fully comprehensive and machine-readable SBOM.
  • SBOM should include the dependencies and transitive dependencies present in the entire device ecosystem.
  • CycloneDX and SPDX can be used to create standard forms of SBOM.
  • VEX can help identify whether the vulnerabilities of components are affecting the device or not.
  • Automation of SBOM generation within the CI/CD pipeline will ensure that software inventory is kept up-to-date.

What Is a Software Bill of Materials (SBOM) for IoMT Software?

A healthcare software bill of materials sbom for IoMT software is a machine-readable architectural representation of all software components. It also includes third-party libraries, open-source packages, and firmware elements that are included within an IoMT device. 
To comply with established government baseline guidelines such as Minimum Elements for an SBOM (NTIA/CISA), the following seven metadata elements need to be provided for every component integrated within your IoMT device:
  • Name of Supplier: Original manufacturer, developer, or open-source entity behind a particular software component.
  • Name of Component: Standard name of the particular software package.
  • Version of Component: Exact version of the software library used in your build.
  • Unique Identifiers: Common keys, such as Package URL, that identify a particular software component.
  • Dependency Relationships: Relationships between different software components.
  • Author of Data: The exact tool or entity that created the inventory document.
  • Timestamp: Date and time when the software inventory was created in your build process.
