Introduction to Threat Modeling for Secure Software Development

Building secure software requires identifying potential vulnerabilities before a single line of code is deployed. Threat modeling provides a structured engineering approach to pinpointing security risks early in the development process, saving time and preventing costly breaches.\n\nIn this text-only course, you will transition from reacting to security incidents to proactively designing secure systems. You will learn how to break down complex application architectures, identify potential threats, and implement effective mitigations using modern security frameworks.\n\nWhat you'll learn:\n- Understand foundational security concepts, threat modeling terminology, and the core four-step framework.\n- Analyze application architectures using data flow diagrams and trust boundaries.\n- Apply the STRIDE methodology to systematically identify software vulnerabilities and design flaws.\n- Integrate modern security principles like Zero Trust and least privilege into your threat models.\n- Determine how to prioritize, track, and mitigate identified threats within modern DevOps workflows.\n- Practice evaluating real-world system designs through written scenarios and exercises.\n\nThis course begins with essential security definitions and foundational concepts before guiding you through step-by-step threat modeling methodologies and practical mitigation strategies. It is designed for software developers, system architects, and aspiring security professionals who are new to threat modeling, with no prior security experience required.
