Secure Software Development: Verification and Threat Modeling Basics

In an era of constant cyber threats, building secure software is no longer optional—it is a core engineering requirement. This text-only course introduces you to the fundamental principles of verification, threat modeling, and defensive design to help you write code that resists attacks. You will transition from writing functional code to designing resilient, secure systems. You will understand how to identify potential vulnerabilities early in the development lifecycle, apply basic cryptographic concepts correctly, and respond rapidly when security issues arise. What you'll learn: - Understand foundational security principles, including the CIA triad, defense in depth, and the secure software development lifecycle (SSDLC). - Apply basic threat modeling techniques to identify and mitigate architectural weaknesses before writing code. - Learn cryptography essentials, including secure hashing, symmetric and asymmetric encryption, and safe key management practices. - Practice security verification techniques such as static analysis, dynamic testing, and automated dependency scanning. - Implement software supply chain security basics, including Software Bill of Materials (SBOM) generation and vulnerability tracking. - Design rapid response and remediation workflows to patch vulnerabilities efficiently after deployment. This text-based program begins with core security terminology and architectural concepts before guiding you through threat modeling methodologies, cryptographic implementation, and modern verification workflows. You will learn through clear written explanations, practical code examples, and structured conceptual exercises. This course is designed for beginner developers, software engineers, and system architects who want to build a solid foundation in software security. No prior security experience is required.
