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 needed to perform threat hunting exercises?

So, what does it take to perform a threat hunting exercise? The short answer to this question is information – information about your assets, the network connections that traverse between your assets, and the interactions users have with your assets. The more detailed the information is you have about these three aspects, the more successful your threat hunt will be.

Although the exact types of data and information needed for the job depend on the specifics of the threat hunt, having the following types of information readily available will help you get started in most scenarios. Along the way, additional information might be needed and will have to be obtained to keep the threat hunt exercise going or to expand its coverage.

Network traffic logs

Because we are dealing with networked systems and equipment that we are performing threat hunting exercises on, the foremost valuable information we should have at our disposal...
