This module transitions you from general secure SDLC concepts to the practical, hands-on application of threat modeling. You will learn the core principles of the STRIDE methodology (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) and how to apply it to real-world system architectures. We will cover data flow diagrams (DFDs), trust boundaries, and the process of generating actionable mitigation strategies. The module culminates in a hands-on guided lab where you will analyze a sample application architecture, identify STRIDE threats, and design a comprehensive threat model and mitigation plan.
