In an era where data breaches and cyber threats are on the rise, it’s no longer enough to simply code and test for functionality - security must be woven into every stage of software design. Our Secure Software Design Principles session equips developers, architects, and team leads with the critical know-how to identify risks early, minimize vulnerabilities, and build robust systems from the ground up. Attendees will learn how to integrate best practices - like least privilege, defense in depth, and threat modeling - into their daily workflows, setting a foundation for resilient and trusted applications. Ultimately, this workshop isn’t just about avoiding pitfalls, it’s about proactively shaping software that is both high-performing and secure by design.
