Open-source software security is crucial in today's cloud-native world. Learn about vulnerabilities, dependencies, and tools to improve security in this in-depth blog post.

As cybersecurity becomes increasingly important in software development, the “shift left” security approach is widely recognized as a best practice for ensuring superior application security. Numerous traditional security firms are introducing shift-left products and capabilities, and the concept is gaining traction. However, some open source application security tools are more developer-friendly than others.

A necessary step in securing an application is evaluating the supply chain of each component used to create the application—no matter how many hands were involved in its development. If any links in the supply chain are obscured, it can be difficult to confidently assess the amount of risk that an application is susceptible to.

In late March 2024, the cybersecurity community was shaken by the revelation of a critical vulnerability in XZ Utils, a popular open source compression tool integral to many Linux systems. The discovery was made by Andres Freund, a developer at Microsoft, who reported that versions 5.6.0 and 5.6.1 had a backdoor that could potentially allow unauthorised remote code execution.
