The Threat Modeling Manifesto – Part 2

How did a group of experienced practitioners turn months of disagreement into a usable Threat Modeling Manifesto? Part two follows the contributors as they refine principles, test language, and decide what belongs in the final document. The discussion compares recipes with adaptable patterns, examines the gap between documentation and shared understanding, and confronts the difficulty of proving threat modeling’s return on investment. Contributors including Alyssa Miller, Irene Michlin, Fraser Scott, Chris Romeo, and Robert Hurlbut debate whether guidance is essential or optional and whether patterns and anti-patterns can make it more actionable. The episode ends with the final principles and a complete acknowledgement of the people who created the Manifesto.
