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 1 – Setting up and configuring Security Onion

As the first exercise for this chapter, we are going to deploy and configure a Security Onion VM. We will be extending the functionality of this Security Onion appliance throughout the remainder of this part of the book and will be using its analytics and search capabilities extensively throughout the third part of this book, Part 3 – Threat Hunting.

Deploying the Security Onion VM

We will now deploy a Security Onion VM for our lab environment. Follow along with the next process to get the VM up and running:

  1. Head on over to https://securityonionsolutions.com/software/ and download the latest version of the Security Onion appliance (2.3.21 as of the writing of this book), as illustrated in the following screenshot:
