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.

Encrypting communication data and TPM

Even though encryption would be a part of firmware security, attackers can often sniff the data being passed between two different hardware components. To ensure that none of your sensitive information is getting into the hands of attackers, make sure that you are encrypting data that is in transit as well as at rest.

One of the other things to consider when talking about encryption in embedded devices is the amount of resources it would take to perform a certain encryption function.

Since the devices are low on resources, performing extremely strong crypto wouldn't be feasible-thus, a good balance between encryption and usability should be thought about ahead of time and implemented in the hardware.

If possible and when the chip supports it take advantage of the TPM to store all the various cryptographic keys, which can also provide functionalities such as a root of trust, preventing modifications to the boot up process. Most TPMs support an effective...
