Primer on attacks and countermeasures

Now that we have briefly visited threats, vulnerabilities, and risk, let's dive into greater detail on the types and compositions of attacks present in the IoT and how they can be put together to perform attack campaigns. In this section, we will also introduce attack trees (and fault trees) to help readers visualize and communicate how real-world attacks can happen. It is also our hope that they gain wider adoption and use in broader threat modeling activities, not unlike the threat model example later in this chapter.
