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.

Why proper architecture matters

Any solid design starts with a sound foundational architecture. This holds true for ICS cybersecurity as well. Spending the proper amount of time to come up with a solid architecture that takes security, performance, uptime requirements, and resiliency into consideration will pay in dividends throughout the lifetime of the ICS environment. The effects of the decisions and considerations we've made will ripple into anything we do later on, so let's go over some fundamental requirements, considerations, and recommendations.

In Chapter 4, Designing the ICS Architecture with Security in Mind, we will take a closer look at the security aspects around a well-designed ICS network architecture. The rest of this chapter will be an architectural overview/review of the recommended ICS network architecture, updated with new and revised considerations since the first edition of this book hit the shelves.
