The IoT Hacker's Handbook: A Practical Guide to Hacking the Internet of Things

Take a practioner's approach in analyzing the Internet of Things (IoT) devices and the security issues facing an IoT architecture.
You'll review the architecture's central components, from hardware communication interfaces, such as UARTand SPI, to radio protocols, such as BLE or ZigBee. You'll also learn to assess a device physically by opening it, looking at the PCB, and identifying the chipsets and interfaces. You'll then use that information to gain entry to the device or to perform other actions, such as dumping encryption keys and firmware.
