Practical Threat Modeling: Design and Build Secure Systems

Security cannot be an afterthought in modern software development. To build resilient applications, you must learn to think like an attacker and identify vulnerabilities before they can be exploited. This text-based course guides you through the core principles of threat modeling, enabling you to systematically analyze system architectures, identify potential security flaws, and implement effective mitigations. You will transition from understanding basic security concepts to mapping complex attack paths and facilitating collaborative security workshops. What you'll learn: Understand foundational threat modeling methodologies like STRIDE and PASTA; Map real-world adversary behaviors using the MITRE ATT&CK Navigator; Visualize attack paths and construct threat trees using modern tools like Deciduous; Design and facilitate productive threat modeling workshops with cross-functional teams; Apply modern DevSecOps principles to integrate threat modeling into the development lifecycle; Formulate actionable mitigation strategies to secure cloud and software architectures. You will start with essential security definitions and risk assessment frameworks before moving step-by-step through practical scenarios, system mapping, and collaborative defense strategies. This course is designed for aspiring security analysts, software developers, systems architects, and beginners looking to build a strong foundation in proactive security design, with no prior threat modeling experience required.
