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.

Hardening embedded frameworks

Designing and building embedded firmware can be complex, with all its dependencies and spaghetti makefiles that have not been touched for decades. Despite these common complexities, establishing a foundation to build secure software starts with the hardening of the platform and toolchain. Many Embedded Linux devices use BusyBox which contains common GNU utilities. There are certain configurations to be made to BusyBox and also updates for it as well. In addition to BusyBox, embedded frameworks, and toolchains should be modified to only those libraries and functions being used when configuring firmware builds. RTOS systems often have POSIX utilities available as well but configured by SoC, MCU, and chip vendors who have modified versions of common utilities. Embedded Linux build systems such as Buildroot, Yocto, and others perform the task of setting up and configuring the toolchain environment. Removal of known insecure libraries and protocols such as Telnet...
