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.

How to simulate (Chinese) attackers

To make your logs look interesting and have certain attackers stand out, we will configure our IT firewall to route into and out of a VLAN with the IP subnet range. The range will show up in location-aware tools as coming from China. What else stands out like a sore thumb more than suspicious traffic from or to China?

To accomplish this, we will virtually wire up the IT firewall to a dedicated vSwitch and assign the connected interface of the firewall with the IP address:

This will put the subnet into the firewall's routing table and send traffic from and to that subnet to the assigned interface. Next, we will connect a copy of Kali Linux to the same vSwitch for the China subnet and assign it an IP address of, with a default gateway of
