The Key to Application Security: Software Bill of Materials

Today’s software applications usually include a vast number of third-party component pieces. As a result, companies need to actively watch and manage each one to preserve security and functionality.

A software bill of materials is frequently used by software engineers to track these components. This machine-readable list comprises all of the software’s numerous elements and dependencies.

In this article, you will learn about the software bill of materials and why it is vital for your application.

What is a Bill of Materials?

A bill of materials is a term used in the manufacturing industry to track the components, parts, and raw materials used in products like automobiles, electronics, and food items. A bill of materials is basically a manufacturing plan that details every component’s route through the supply chain.
What is a Software Bill of Materials?

A software bill of materials is a list of all the open-source and third-party components present in a project. A software bill of materials also lists the licenses governing those components, the versions of the components used in the codebase, and their patch status. A software bill of materials allows you to respond quickly to the security, license, and operational risks associated with using open source components.

As today’s applications are often created with numerous software components, frequently from a mix of open source and proprietary source packages, software bills of materials have become increasingly relevant and beneficial. Given these intricacies, it becomes virtually impossible for businesses and individuals using the software to have complete insight into the software supply chain and potential licensing compliance, security, and quality problems without a software bill of materials.

Software Bills of Materials are the Key to Application Security

There are various advantages to increasing openness about what code components exist in software. Most significantly, it enables businesses to reduce risk by making the early detection and mitigation of susceptible systems and license-violating source codes possible. It also encourages safe software development practices by allowing developers to examine the code they embed in their own work properly.

Greater transparency benefits software users by allowing them to make more informed purchase decisions, especially when it comes to software license compliance. By far, the most significant benefits of having a software bill of materials are in the area of cybersecurity and risk reduction.

Extra Security

Companies may use software bills of materials to identify and eliminate vulnerabilities before they enter production. New vulnerabilities found in commercial software can be fixed quickly. Secondly, software bills of materials assist developers in discovering and resolving security problems more quickly.
Improved License Compliance

Companies must proceed cautiously when employing open-source software to avoid license issues. Failure to meet software requirements can result in reputational damage, lawsuits, fines, and other consequences. Furthermore, certain agreements can protect users against claims, but only if they know what software they’re using.

Software bills of materials help businesses manage to license risks by enabling the due diligence process and helping avoid the deployment of non-compliant software.

Easier End-of-Life Management

When a software component reaches the end-of-life stage, the supplier ceases to maintain it. Furthermore, they will no longer receive important upgrades and security fixes. When components approach the end-of-life stage, developers rely on software bills of materials to detect them.

Software bills of materials can assist in identifying a replacement and preventing old and vulnerable components from staying in use.

Reduced Code Complexity

Software iteration usually results in inefficient and bulky software, a condition known as code bloat. This happens when developers combine many components that accomplish the same function. Coad bloat also increases the number of components that need to be kept in good working order.

Software bills of materials can assist developers in identifying superfluous coding, making it simpler to reduce redundant or unneeded supplementary tools. This implies that services will be quicker, cleaner, and safer.

What’s in a Software Bill of Material?

Open Source Components

A well-written software bill of materials displays the licenses, versions, and patch status of all open source components in your app.

Open Source Licenses

A software bill of materials outlines the open-source licenses that apply to the components you employ, allowing you to estimate your legal and intellectual property risk.

Open Source Versions

A software bill of materials specifies the versions of open source components in your codebase, allowing you to see whether you’re utilizing any old, possibly insecure code.


Any organization that creates software must keep a software bill of materials for each project. To produce software, organizations frequently use a combination of custom-built code, commercial off-the-shelf code, and open source components.
