Overview of this book

The Fourth Industrial Revolution, or Industry 4.0, is all about digital transformation, manufacturing, and production. The connected world we live in today, including industries, comes with several cybersecurity challenges that need immediate attention. This book takes you through the basics of IoT and OT architecture and helps you understand and mitigate these security challenges. The book begins with an overview of the challenges faced in managing and securing IoT and OT devices in Industry 4.0. You’ll then get to grips with the Purdue model of reference architecture, which will help you explore common cyber attacks in IoT and OT environments. As you progress, you’ll be introduced to Microsoft Defender for IoT and understand its capabilities in securing IoT and OT environments. Finally, you will discover best practices for achieving continuous monitoring and vulnerability management, as well as threat monitoring and hunting, and find out how to align your business model toward zero trust. By the end of this security book, you’ll be equipped with the knowledge and skills to efficiently secure IoT and OT environments using Microsoft Defender for IoT.

The installation of the MDIoT service

This is what is required for you to get started with MDIoT:

  • A Microsoft Azure subscription and account
  • Owner or Contributor access to the Azure subscription

For the test lab setup, you could configure all the roles and services with the global admin account itself. But if this is being planned on a production tenant, you might want to consider leveraging a role such as security reader, security admin, security contributor, or subscription owner to establish a separation of duties.

It would be wise to also consider the availability (i.e., traffic from all European regions is routed through West Europe, and all other regions are routed through the East US regional data center) of all the regions that MDIoT and the Azure IoT hub are available in and whether your data residency covers the region as specified in the compliance policy of your organization or the residing country.

The following are things to keep in mind when...
