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 10: Threat Hunting

In the previous chapters, we looked at gathering security-related information from the ICS environment and how to store it so that we can query, correlate, visualize, and manipulate with and around that information. Now that we have the tools in place, let's look at a very specific usage of those tools and the security-related information we collected by performing threat hunting.

In this chapter, we will discuss the ins and outs of threat hunting and how it can be used in the ICS environment to prove or disprove that there are malicious actors present, or that malicious activity is taking place. As part of this introductory chapter to threat hunting, we will look at the principles of threat hunting activities and the tools that are used as part of threat hunting exercises. One toolset we will look at in particular and use extensively throughout this part of this book is called Elasticsearch, Logstash, and Kibana (ELK). We discussed the technical...
