Software Bill of Materials: How it Helps in Securing Software Supply Chain

Software is an integral part of our daily lives, whether we realize it or not. From the operating systems on our computers to the apps we use on our phones, software is all around us. However, as reliance on software grows, so does the importance of securing the software supply chain. This is where the concept of a Software Bill of Materials (SBOM) comes in.

A SBOM is a list of all the components that make up a software. This includes the version numbers of each component, the licenses under which they are distributed, and any known vulnerabilities associated with them. Having a SBOM allows for better visibility into the components used in software, making it easier to identify and fix vulnerabilities and ensure compliance with industry standards and regulations.

This blog post will delve into the details of SBOM and how it can help secure the software supply chain.

What is a SBOM?

A SBOM, or Software Bill of Materials, is a comprehensive list of all the components that make up a software. These components can include everything from open source code libraries and frameworks to third-party tools and services. The SBOM should include detailed information about each component, including version numbers, licenses, and any known vulnerabilities.
One of the main purposes of a SBOM is to provide a clear and accurate record of all the components used in a piece of software. This can be especially important for companies that rely on multiple teams or third-party vendors to develop their software, as it can be challenging to keep track of all the different components used. A SBOM helps ensure that everyone involved in the development process clearly understands what is being used and where it came from by providing a detailed list of all the components.

How Does a SBOM Help in Securing the Software Supply Chain?

A SBOM, or Software Bill of Materials, is an important tool for securing the software supply chain in several ways including:
  • Improved Visibility
    SBOM allows for better visibility into the components used in the software. By providing a comprehensive list of all the components that make up a piece of software, a SBOM helps ensure that everyone involved in the development process clearly understands what is being used and where it came from. This can be especially important for companies that rely on multiple teams or third-party vendors to develop their software. It can be challenging to keep track of all the different components being used without a central record.
  • Vulnerability Resolution
    SBOM also makes it easier to identify and fix vulnerabilities. By including information about known vulnerabilities in the SBOM, companies can quickly identify any potential security risks and take steps to fix them before they become a problem. This can help protect against possible cyberattacks and other security breaches, making it an essential tool for securing the software supply chain.
  • Compliance and Risk Management
    SBOM can also help with compliance and risk management. Many industries have specific regulations and standards that must be followed when developing software. A SBOM can help ensure that all the components used in a piece of software comply with these regulations. Additionally, by providing a comprehensive record of all the components used in software, a SBOM can help companies identify and mitigate potential risks, such as using components with known vulnerabilities or components that are no longer supported by the vendor.

How to create and maintain a SBOM

A SBOM is an essential tool for securing the software supply chain and ensuring the quality and security of software. Here are some tips for creating and maintaining a SBOM:
  • Use automated tools for generating SBOMs: Several tools including CycloneDX, Syft, Microsoft, Fossa, Anchore, Mend, etc., can automatically generate a SBOM by scanning a piece of software and identifying all the components used. These tools can be especially helpful for large projects with many components, as they can quickly and accurately generate a SBOM without requiring manual input.
  • Use a manual process for creating a SBOM: If automated tools are not available or not suitable for your needs, you can also create a SBOM manually. This involves manually identifying all the components used in a piece of software and creating a list of these components with relevant details such as version numbers, licenses, and known vulnerabilities. This process can be time-consuming, but it can effectively create a SBOM for smaller projects or projects with unique requirements.
  • Keep the SBOM up to date: It’s important to regularly review and update the SBOM to ensure that it remains accurate and complete. This includes adding new components as they are introduced, updating information about existing components, and removing components that are no longer used.
  • Establish a process for maintaining the SBOM: To ensure that the SBOM is consistently maintained, it’s important to establish a process for keeping it up to date. This could involve assigning specific individuals or teams to review and update the SBOM regularly or setting up automated processes to scan the software for changes periodically.
By following these best practices, you can create and maintain an accurate and comprehensive SBOM that helps secure the software supply chain and ensure the quality and security of your software.
