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 2 – Manually inspecting an industrial computer

In this second exercise, we will be manually inspecting Microsoft Windows-based systems and learning how to gather information such as system/OS details, installed software, start up items, and users. This information is essential if, at some point, we want to have something to compare against. This allows us to, for example, compare configured users at some point in time against users we've configured previously, potentially allowing us to identify a new administrator account that's been added to the system.

Pulling Windows-based host information

Microsoft Windows OSes keep track of all kinds of information in a variety of locations. The trick is to find a way to extract this information in a convenient manner that works across a variety of Windows flavors. There are (external) utilities that can help with these efforts, but I believe that if it's not absolutely necessary, we shouldn't run external...
