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 – Scanning network-connected devices

In this first exercise, we are going to look at some network scanning techniques aimed at finding live systems on our network. We will utilize this to figure out what is running on these live systems. Additionally, we will look at some methods we can use to unearth if there are any vulnerabilities present on the live systems.

For this exercise and most of the other exercises in this book, we will be using the (in)famous Kali Linux distribution, which can be downloaded from https://www.kali.org/downloads/. As for help with installing Kali, performing a simple search on your favorite search engine should result in dozens of tutorials to get you started.

Dangers of scanning in the ICS environment

Before we dive into the art of network scanning, a word of caution: if you perform active scanning on a live (operational) ICS network, things can – and often will – go wrong. Although the resiliency of industrial...
