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.

Antitamper and hardware protection mechanisms

Tamper resistance means using specialized components to protect against tampering with a given device. One of the common and effective ways of implementing antitampering, which can strengthen the hardware security of a device, is by adding tamper detection switches, sensors, or circuitry in the device, which can detect certain actions such as the opening of the device or its forceful breakage, and would act based on that by deleting the flash memory, or making the device unusable.

Along with this, it is highly recommended to protect sensitive chips and components by removing their labels, hiding them with epoxy, and even encapsulating the chips in a secure enclosure.

Some other techniques of implementing tamper resistance include incorporating tight airflow channels, security screws and hardened steel enclosures-all of which would make tampering with the device extremely difficult.
