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.

Industrial control system architecture overview

The following diagram depicts the recommended ICS network architecture. Fundamentally, it has not changed from what we discussed in the first edition of this book. The recommended architecture is based on the Purdue model (the Purdue model was discussed in detail in Chapter 1, Introduction and Recap of First Edition) but was updated to reflect current standards, industry best practices, and 10 years' worth of experience by this author designing, implementing, and maintaining secure and resilient industrial network architectures.

Rather than go over every section, zone, and area, here, we will look at the architecture from an implementation perspective. What kind of technology is behind setting up the segments, boundaries, and security controls?
