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.

Exercise 6 – Creating a breach detection dashboard in Kibana

Event log collection and correlation systems can bring in a ton of data. Our simple lab setup, for example, is pulling in around 1,000,000 events every 24 hours, and that is for a handful of systems and devices. The way we can deal with this much data is by using it to pinpoint areas of concern, events, or trends that seem suspicious. That is the kind of information we want to visualize so that an analyst can quickly assess if something fishy is going on. At this point, they will use all the other data we have been accumulating to find the smoking gun that proves an incident is occurring or as supporting data to perform forensics and incident response activities. The other way we can use this tremendous amount of detailed information is during threat-hunting exercises, which we will cover in Section 3, Threat Hunting.

Throughout this exercise, we will be adding widgets and visualizations to a custom dashboard within...
