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.

What is threat hunting?

In Chapter 6, Passive Security Monitoring, we discussed ways to detect, record, and identify security-related risks and information in our ICS environment without interacting with systems on the network. Then, in Chapter 7, Active Security Monitoring, we looked at the opposite of that methodology, namely using active techniques to unearth security-related information and find risk in the industrial network. Finally, in Chapter 9, Visualizing, Correlating, and Alerting, we took the findings and information from all our active and passive tools and activities, and then combined them into a Security Incident and Event Management solution. This provided us with a way to correlate and search for risks. It also allows us to set alerts on detected security incidents and visualize the current risk posture of our environment. Now, it is time to use the information and data our security monitoring efforts are giving us in a more proactive and investigative way, which...
