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.

Example IDMZ broker-service solutions

In the following sections, we will look at four specific IDMZ broker-service solutions. We will discuss their enterprise, IDMZ, and industrial components, as well as seeing how things tie together, and we will briefly touch on proper installation and configuration.

Remote access to industrial control system applications and devices

The first—and probably most common—broker-service scenario we will discuss is remote interactive access to the industrial network. Every IDMZ implementation I have done to date has had a remote interactive access solution as part of the design.

A remote access solution is used to allow enterprise virtual private network (VPN) users or vendors to access resources on the industrial network remotely and securely.


The design of the IDMZ remote access broker-service solution is built around Microsoft's RDP. The RDP is a Microsoft proprietary protocol that provides a user with the...
