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.

Chapter 7: Active Security Monitoring

In the previous chapter, we looked at ways to passively be on the lookout for security incidents and risk development in our ICS environment. Even though being passive (sniffing, monitoring, event scrutinizing) is still the preferred way to detect security-related events and information, what follows is a discussion on how to use more involved methods to detect these events. If performed properly, active security monitoring techniques can be used effectively and without disrupting production, with the added benefit that active security monitoring tends to uncover more and more detailed security and risk-related data from our production network and connected systems.

In this chapter, we will look at the tools, techniques, activities, and procedures surrounding actively monitoring the industrial cybersecurity posture. We will discuss the thought process behind the techniques and tools, and then gain some hands-on experience with a couple of exercises...
