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.

Chapter 9: Vulnerability Management and Threat Monitoring

Vulnerability Management and Threat Monitoring

In the previous chapters, we started learning about the core features of MDIoT. Let us continue in that spirit and move on to learning about risk and vulnerability management along with threat monitoring.

Risk management in IoT/OT incorporates identifying, analyzing, and controlling threats aimed at an organization’s IoT/OT security. We learned about the challenges of cybersecurity in Industry 4.0 in Chapter 1, and we have to ensure that the risks are known to the management and are assessed with risk mitigation steps in place.

Risk assessment forms an integral part of MDIoT. The most vulnerable devices, variations from the baselines, remediation priorities based on a secure score, network security risks, illegal traffic by firewall rules, connections to Industrial Control System (ICS) networks, internet connections, access points, industrial malware, indicators, unauthorized assets, weak firewall rules, network operations...
