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.

How Do the Microsoft Defender for IoT Features Help in Addressing Open Challenges?

We have seen in earlier chapters some of the challenges in securing organizations that follow Industry 4.0 standards. These organizations reap the benefits of Industry 4.0 and the automation it brings forth, and forget to consider the security aspect.

In this chapter, we will focus on the areas that an IoT/OT organization might overlook when it comes to ensuring security and the impact this could have. At the end of this chapter, we will also learn about sensor installation, which is a starting step in your practical journey to MDIoT.

We will cover the following topics in this chapter:

  • Missing asset inventory for IoT/OT devices
  • Risk and vulnerability management
  • Continuous IoT/OT threat monitoring, incident response, and threat intelligence
  • The installation of the MDIoT service
