Lessons in threat modeling: How attack trees can deliver AppSec by design

This article outlines how attack trees can make threat modeling more approachable and effective by hierarchically visualizing attack paths, exposing weak points, and enabling targeted mitigations. Experts argue that combining attack trees with traditional threat modeling improves context, prioritization, and communication across stakeholders, particularly in complex environments like IoT. The piece emphasizes that efficacy depends on ongoing maintenance as systems and threats evolve, positioning attack trees as a complementary tool to achieve secure-by-design outcomes throughout the SDLC.
