Summary

In this episode, Jacob Beningo interviews Frank Herta, the CEO of Curtail Incorporated, about the risks of zero-day attacks in open source software. They discuss the importance of DevSecOps and the need for comprehensive security measures. Frank shares his background in security and how his company is working on detecting zero-day bugs. 

They also explore the vulnerabilities of open source software and the potential for third-party supply chain attacks. Open source software testing differs from proprietary software testing in terms of who is responsible for testing. Open source projects have their own testing processes, but it's important for software developers to test the open source software in the context of their own applications. 

DevSecOps is a cultural shift that aims to integrate security and testing throughout the software development process. It involves early testing, collaboration between teams, and a focus on security from the beginning. The nature of threats in open source software is changing, with third-party attacks on repositories becoming a major concern. Complacency and slow response times are also issues that need to be addressed. 

Developers and managers using open source software should follow security best practices, stay updated on vulnerabilities, and actively test their software. Curtail is working on innovative solutions to analyze and compare different open source packages for better security.
