Go developers should adopt secure coding practices against supply chain attacks.
Deep dives
Introducing Dependency Vulnerabilities in Polyfill.io CDN
Polyfill.io, a CDN serving JavaScript browser polyfills, was compromised by a different company triggering the injection of malicious JavaScript affecting websites like Hulu and JSTOR. The incident highlights the importance of verifying CDNs and monitoring potential security breaches.
Challenges of CDNs in Front-End Development
While CDNs are essential for faster website loading times, the polyfill.io compromise underscores the inherent risk of widespread CDNs becoming prime targets for attackers due to the vast reach of these services.
Supply Chain Concerns for Developers
The podcast highlights supply chain security challenges in web development where dependencies from CDNs or libraries can introduce vulnerabilities. Developers are urged to scrutinize dependencies, especially those with broad usage like CDNs, to mitigate security risks.
Securing Go Applications Against Supply Chain Attacks
Go developers are encouraged to stay vigilant against supply chain attacks by adopting secure coding practices. The Go community's focus on code review, dependency management, and security-conscious development contributes to mitigating potential risks.
The Importance of Understanding Low-Level Concepts in C Programming
Learning C or similar low-level languages provides a fundamental understanding of memory management, system nuances, and hardware interactions crucial for robust software development. Mastery of low-level concepts enhances developers' ability to create efficient and secure applications.
Dependencies! We need them, but how do we use them effectively and safely? In this week’s episode Kris is joined by Ian and Johnny to discuss the polyfill.io supply chain attack, the history of dependency management and usage in Go, and the Go Proverb that “a little copying is better than a little dependency”. Of course, we wrap up the episode with some Unpopular Opinions!
