Software supply chain attacks have become a top security concern for modern engineering teams. This article explores the full attack surface, from malicious dependency injection to CI/CD pipeline compromise, and outlines defense strategies that span the entire development lifecycle. Key areas include dependency verification, pipeline access control, artifact integrity checks, and continuous monitoring. The author emphasizes that security must be integrated into every stage of the build and deployment process, not treated as an afterthought. For teams using open-source components and automated pipelines, understanding these threats is critical to preventing costly breaches. The article also touches on real-world attack examples and how organizations can learn from them to strengthen their own defenses.
A practical guide to defending against software supply chain attacks, covering dependency poisoning, CI/CD hijacking, and full-chain defense strategies.
