Foundations of Secure Software Design and Coding

Software security is no longer an afterthought; it must be built into your applications from the very first line of code. Many security breaches stem from preventable design flaws and coding errors that accumulate as software grows and evolves. This text-only course guides you through the core principles of secure software development, helping you shift your mindset from simply writing functional code to designing resilient systems that protect user data and resist modern cyber threats. What you'll learn: - Understand foundational security concepts, including confidentiality, integrity, and availability. - Identify and mitigate common software vulnerabilities, such as those outlined in the modern OWASP Top 10. - Apply threat modeling techniques to discover and address potential security flaws during the design phase. - Implement defensive coding practices to prevent injection, broken authentication, and sensitive data exposure. - Integrate zero-trust principles and secure development lifecycle concepts into your workflow. The course begins with essential security terminology and foundational concepts before moving into practical secure design patterns. You will then explore defensive coding techniques and modern security practices through detailed written explanations and clear code examples. This course is designed for beginner software developers, systems analysts, and computer science students who want to build a strong foundation in application security. No prior security experience is required. Start building safer, more resilient software today.
