Secure SDLC and Threat Modeling
How to design security in from the first sketch instead of bolting it on before launch — mapping security work to every phase of the software lifecycle, grounded in the NIST Secure Software Development Framework, and using STRIDE-based threat modeling as the core design activity.
Designing security in from the start: the secure SDLC mapped to NIST SSDF, security requirements and abuse cases, and threat modeling with the four questions and STRIDE — data-flow diagrams, trust boundaries, and continuous (not one-time) modeling.
