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.

Discussing the lab architecture

The following diagram is a depiction of the lab architecture that I use to experiment and practice on. Full disclosure – I sometimes add an Industrial Demilitarized Zone (IDMZ) to the mix for particular testing scenarios. Most of the hardware in the lab can and will be used for customer engagements such as penetration tests and red teaming scenarios:

Figure 19.1 – Lab architecture

The depicted lab architecture allows us to simulate/emulate the internet, the enterprise zone, and the industrial zone (including enclaves/segments), as well as the typical systems/devices found in those areas. As we will discuss, the lab architecture uses a combination of virtual and physical devices and systems to create a flexible and configurable environment that can be shaped and formed for a variety of tasks.

The lab hardware

Currently, I am running the virtualization part of the lab architecture on two well-equipped Dell...
