What does it take to transform cybersecurity from reactive patch management to proactive secure design? Adam Shostack, the world's leading expert on threat modeling, takes us inside Microsoft during its pivotal security transformation in the early 2000s and reveals how those lessons shaped FDA's approach to medical device cybersecurity today.

From the auto-run vulnerability that infected millions of computers monthly to creating the STRIDE methodology now used worldwide, Adam shares the origin stories behind fundamental cybersecurity practices. He explains how threat modeling evolved from expert-driven whiteboard sessions to systematic, scalable processes that any engineering team can implement.

Shannon and Adam explore the critical difference between risk management and threat modeling in design, why "pouring concrete and then wondering about properties" fails in cybersecurity, and how FDA's pre-market guidance ensures patient safety while fostering innovation. They dive deep into the four key questions every threat modeler must answer and why starting threat modeling with a simple napkin sketch can prevent costly architectural changes later.

Key Topics:

• Microsoft's trustworthy computing transformation and lessons learned

• The invention and evolution of STRIDE methodology for systematic threat analysis

• How FDA adopted threat modeling for medical device cybersecurity regulation

• The fundamental difference between threat modeling and risk management

• Why current approaches to software understanding and composition analysis fall short

• Practical advice for scaling threat modeling across organizations

• The future of threat modeling with AI assistance
