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.

Threat modeling IoT radio communication

Moving on to radio/wireless communication, our DVR does not have much going on with regards to radio communication other than the data that transports to the DVR from client applications or cameras. Most IoT devices and environments have several different radio communications broadcasting on different frequencies using different protocols. Luckily, we only have to worry about Wi-Fi and cell provider entry points into the DVR.

How to do it...

For our radio communication threat modeling exercise, we can simply update previously drawn diagrams to reflect the radio communication that occurs within devices and applications.

Step 1: Creating an architecture overview and decomposition

An example architecture overview for radio communication usage within the DVR system is illustrated as follows:

As you may be able to tell, the wireless communication is limited to users accessing the DVR via client devices such as a browser and applications as well as wireless-enabled...
