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.

Securing sensitive information

With limited storage and slim margins, securing sensitive data can be a challenge for IoT devices. Often, sensitive data is stored on a client application or device so an IoT service can function without an internet connection. There are secure principles to be followed when securing sensitive data on a device. First, never hardcode secrets into firmware images such as passwords, usernames, tokens, private keys, or similar variants, into firmware release images. This also includes the storage of sensitive data that is written to a disk. This data will be accessible to attackers upon extracting firmware filesystems as well as when accessing the operating system during runtime. If hardware such as a security element (SE) or Trusted Execution Environment (TEE) is available, it is recommended to use such features for storing sensitive data during runtime. Otherwise, use of strong cryptography should be evaluated to protect the data using server-side computations...
