Secure Software Development: Requirements, Design, and Reuse

In an era of constant cyber threats, building security into your software from day one is no longer optional—it is a fundamental engineering requirement. This text-based course guides you through the essential principles of designing, planning, and maintaining secure applications. You will transition from writing functional code to engineering resilient, hardened systems. You will understand how to identify potential vulnerabilities early in the lifecycle, establish robust security requirements, and securely integrate open-source and third-party software. What you'll learn: - Learn foundational security concepts and the core terminology of secure software development. - Define actionable security requirements that align with modern industry standards. - Design resilient systems using proven threat modeling techniques and secure architecture principles. - Apply safe practices for selecting, evaluating, and reusing third-party and open-source libraries. - Understand zero-trust concepts and how to apply them to modern application design. - Formulate response plans to minimize damage and accelerate recovery when vulnerabilities are discovered. The course begins with essential security terminology and foundational definitions before moving step-by-step through threat modeling, secure design patterns, and dependency management. You will read practical examples and analyze real-world scenarios to ground these concepts in daily development workflows. This course is designed for beginning developers, software engineers, and system analysts who want to build a strong foundation in application security. No prior security experience is required. Start reading today to build software that stands strong against modern exploits.
