About this project
Threat modeling is the senior security skill — it requires deep understanding of systems and adversaries. This project teaches the STRIDE methodology: data-flow diagrams, threat enumeration, mitigation mapping, residual-risk acceptance. Pick a real system (an open-source app, or a hypothetical "new feature") and ship a complete threat model.
Why build this in 2026?
AI features need threat models for prompt injection, model exfiltration. Specialty hiring opportunity.
What you'll ship
