IoT Penetration Testing Cookbook

By: Aaron Guzman, Aditya Gupta

Overview of this book

IoT is an upcoming trend in the IT industry today; there are a lot of IoT devices on the market, but there is a minimal understanding of how to safeguard them. If you are a security enthusiast or pentester, this book will help you understand how to exploit and secure IoT devices. This book follows a recipe-based approach, giving you practical experience in securing upcoming smart devices. It starts with practical recipes on how to analyze IoT device architectures and identify vulnerabilities. Then, it focuses on enhancing your pentesting skill set, teaching you how to exploit a vulnerable IoT device, along with identifying vulnerabilities in IoT device firmware. Next, this book teaches you how to secure embedded devices and exploit smart devices with hardware techniques. Moving forward, this book reveals advanced hardware pentesting techniques, along with software-defined, radio-based IoT pentesting with Zigbee and Z-Wave. Finally, this book also covers how to use new and unique pentesting techniques for different IoT devices, along with smart devices connected to the cloud. By the end of this book, you will have a fair understanding of how to use different pentesting techniques to exploit and secure various IoT devices.

Side channel attack protections

One of the obvious protection mechanisms taken to secure hardware is to implement and enable encryption. However, attacks exist whereby encryption can be bypassed, or the key can be obtained extremely easily.

Side channel attacks are an advanced hardware exploitation technique in which an attacker uses different information sources, such as variations in power, timing analysis, electromagnetic data variations, and sound information, to extract more information, which can be used to compromise the target device.

Direct memory attacks (DMA) are a type of side channel attack, which let the attacker access one of the components involved in the functionality of a certain activity directly instead of going the usual route. For example, if we take an example of a USB, the USB connects to the controller hub/platform controller hub (PCH), which can be accessed via direct memory access (DMA).

These attacks are complicated to prevent, however, the following are some of...
