Chapter 1
Dive In and Threat Model!
Anyone can learn to threat model, and what's more, everyone should. Threat modeling is about using models to find security problems. Using a model means abstracting away a lot of details to provide a look at a bigger picture, rather than the code itself. You model because it enables you to find issues in things you haven't built yet, and because it enables you to catch a problem before it starts. Lastly, you threat model as a way to anticipate the threats that could affect you.
Threat modeling is first and foremost a practical discipline, and this chapter is structured to reflect that practicality. Even though this book will provide you with many valuable definitions, theories, philosophies, effective approaches, and well-tested techniques, you'll want those to be grounded in experience. Therefore, this chapter avoids focusing on theory and ignores variations for now and instead gives you a chance to learn by experience.
To use an analogy...
