In an interconnected digital world, software supply chains—processes that convert initial code into final software products—are complex and potentially fraught with security risks.
Threat actors often exploit vulnerable points in these chains, leading to serious consequences like data breaches or service disruption.
It's crucial for organizations to understand these risks and secure their software supply chains effectively.
But what is it, why is it important, and how does it relate to the Software Bill of Materials (SBOM)?
Software supply chain security is the practice of protecting and securing all elements involved in the software development process, including third-party services, open-source libraries, internal development tools, and deployment environments.
This concept goes beyond the scope of traditional application security. It ensures the integrity and confidentiality of your software products from inception to end-of-life.
A software supply chain encompasses all activities and entities involved in the creation, delivery, and maintenance of a software product. This includes the ideation and design, coding, testing, deployment, and maintenance stages of software development.
It also involves various entities such as software developers, third-party service providers, open-source libraries, internal development tools, and deployment environments.
Ensuring the security of this supply chain goes beyond the scope of traditional application security. It aims to ensure the integrity and confidentiality of your software products from inception to end-of-life by mitigating potential risks in all components of the supply chain.
One of the most notable examples of a software supply chain attack is the SolarWinds incident.
In this case, malicious actors compromised the update mechanism of SolarWinds' Orion software, a network monitoring tool used by numerous organizations worldwide.
This compromise allowed the attackers to distribute malicious updates to Orion customers, leading to a significant breach affecting several high-profile organizations.
While software supply chain security and application security might seem similar, they cater to different aspects of software protection.
Application security focuses on the security of software applications from malicious attacks and threats, focusing primarily on the code and features of the software application.
On the other hand, software supply chain security involves ensuring the security of the entire development and distribution process.
It focuses not only on the software application but also on the various components and parties involved in its creation and maintenance. This includes open-source components, third-party vendors, and internal development practices.
Software supply chain attacks are on the rise due to the interconnected nature of modern software development.
As organizations increasingly depend on third-party software and open-source libraries, attackers see an opportunity to exploit vulnerabilities in these components to gain unauthorized access to systems or data.
Also, a successful supply chain attack can have a ripple effect, affecting multiple organizations that use the compromised component. This large-scale impact makes supply chain attacks particularly appealing to sophisticated threat actors.

Open-source software has become a fundamental part of modern software development due to its cost-effectiveness, high quality, and flexibility.
However, its public nature can attract malicious entities. Problems can arise when there is inadequate tracking of open-source components used in applications, leading to potential security vulnerabilities.
For instance, outdated libraries might have known security flaws exploited by hackers. A detailed understanding of open-source licenses and diligent tracking of open-source components can help manage these risks.
Many software products today leverage third-party vendors, services, or APIs. While these third-party integrations can enhance the functionality of your software, they also introduce potential security vulnerabilities.
If these vendors suffer a security breach, it can have severe implications for your software supply chain, leading to data loss or leakage, compliance issues, and reputational damage.
The development practices within an organization also present potential risks to the software supply chain. These include insecure coding practices, lack of adequate testing, poor version control, and inefficient patch management.
Proper training, the implementation of secure coding guidelines, and robust testing and quality assurance procedures can mitigate these risks.
