IoT Penetration Testing Cookbook

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.

Implementing authentication controls


Authentication for mobile applications can occur from both server side and client side. IoT mobile applications can make use of both design patterns although each have their own risk considerations when implementing in production. This section will discuss some of these risks as well as best practice design implementations for server and client-side authentication.

How to do it...

General application principles for securely authenticating users apply to mobile applications as well. A great reference is OWASP's Authentication Cheat Sheet (https://www.owasp.org/index.php/Authentication_Cheat_Sheet). Common authentication controls and best practices consist of:

  • Proper password strength controls
    • Password length
      • 10 characters or more
    • Password complexity policies
      • 1 uppercase, 1 lowercase, 1 digit, 1 special character, and disallowing 2 consecutive characters such as 222
    • Enforce password history
      • Disallow the last three used passwords (password reuse)
  • Transmitting...
