Secure software requires both design-time and code-time protection. STRIDE threat modeling helps identify risks early in system design, while SonarQube enforces secure coding practices through static analysis. Together, they provide a practical, end-to-end approach to building secure applications.

In this article, you'll learn how to apply STRIDE threat modeling and SonarQube static analysis to identify, prevent, and fix security vulnerabilities in modern applications.
