The future of secure software development depends on developers who understand how to design, build, and maintain secure applications. This intensive two-day course provides developers, architects, and tech leads with practical skills to identify and remediate vulnerabilities in their code. Through interactive labs and real-world scenarios, learners will explore modern application security practices and learn to apply threat modelling techniques using the STRIDE methodology. Participants will also gain insight into secure coding patterns, defensive programming, and common exploitation techniques used by attackers.The course bridges theory with hands-on practice to help developers strengthen their security mindset, align development workflows with security principles, and confidently safeguard applications throughout their lifecycle.
