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.

Modeling pentests around the ICS Kill Chain

As we discussed in the previous section, ICS environments are ideal targets for attackers with inherent risks associated with the uniqueness of the ICS environment. Because of these unique characteristics and the architecture of ICS environments, serious attackers will follow a unique approach to attack the industrial network (kill chain). It makes sense to model a pentest around this unique attack approach. One of the best writeups detailing this attack approach comes in the form of the industrial control system Cyber Kill Chain, as presented by the SANS institute, which can be found here: https://www.sans.org/reading-room/whitepapers/ICS/industrial-control-system-cyber-kill-chain-36297.

Let's start our discussion by explaining the Cyber Kill Chain.

The Cyber Kill Chain explained

The concept of the Cyber Kill Chain was first created by analysts of the military defense corporation Lockheed Martin. They published a paper in 2011...
