IoT and OT Security Handbook

By: Smita Jain, Vasantha Lakshmi

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 these attacks impact businesses and humans?

We have, so far, seen some of the impactful attacks in the OT world and have managed to pick up some lessons from each of them. Most of them point us in the same direction: toward finding a stable solution to be able to apply to both the IT and OT worlds. We have seen some of the amazing benefits of the convergence of IT and OT with Industry 4.0 and how it impacts businesses, thrusting them forward toward success in the data and AI worlds. However, when the fast-paced digital transformation is not intertwined with the right security and monitoring, we will see it hampering businesses in a negative way. We have also learned from previous attacks that the impact on the OT world is visible not only on the business (monetary or reputation loss) but also, unfortunately, on human lives too.

It is especially important to understand the risk appetite of any organization. Based on this, they can focus on how to improve their IT/OT security...
