Industrial Cybersecurity - Second Edition

By: Pascal Ackerman

Overview of this book

With Industrial Control Systems (ICS) expanding into traditional IT space and even into the cloud, the attack surface of ICS environments has increased significantly, making it crucial to recognize your ICS vulnerabilities and implement advanced techniques for monitoring and defending against rapidly evolving cyber threats to critical infrastructure. This second edition covers the updated Industrial Demilitarized Zone (IDMZ) architecture and shows you how to implement, verify, and monitor a holistic security program for your ICS environment. You'll begin by learning how to design security-oriented architecture that allows you to implement the tools, techniques, and activities covered in this book effectively and easily. You'll get to grips with the monitoring, tracking, and trending (visualizing) and procedures of ICS cybersecurity risks as well as understand the overall security program and posture/hygiene of the ICS environment. The book then introduces you to threat hunting principles, tools, and techniques to help you identify malicious activity successfully. Finally, you'll work with incident response and incident recovery tools and techniques in an ICS environment. By the end of this book, you'll have gained a solid understanding of industrial cybersecurity monitoring, assessments, incident response activities, as well as threat hunting.

Summary

We have started the continued journey into ICS cybersecurity, with a review of what was covered in the first edition of the book. Whereas the first edition was mainly concerned with establishing a secure ICS environment, this second edition will expand upon this with various topics that deal with maintaining a secure environment by observing and monitoring the security posture. I will be using a "from-the-ground-up" approach to explain all this, meaning we will look at security monitoring and the implementation aspects of it in all phases of the ICS environment life cycle. We start with a revised look at the ICS network architecture and the IDMZ in the next couple of chapters.

In the next chapter, we are going to take a fresh new look at the ICS network architecture. We will be reviewing the parts and pieces that make up a modern ICS network, stretched out over the three distinct parts of the ICS environment: the Enterprise Zone, the Industrial Zone, and the IDMZ.
