CHAPTER 20 Dissecting Embedded Devices

In this chapter, we cover the following topics:

• CPU

• Serial interfaces

• Debug interfaces

• Software

This chapter provides a high-level view of embedded devices with the intention of providing a vocabulary for and high-level understanding of potential areas of concern. Embedded devices are electrical or electro-mechanical devices that meet a specific need or have a limited function. A few examples of embedded devices include security systems, network routers/switches, cameras, garage door openers, smart thermostats, controllable light bulbs, and mobile phones. As our devices gain remote connectivity for our convenience, they also provide more opportunity for an attacker to enter our lives ...
