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.

Chapter 1: Introduction and Recap of First Edition

Welcome to the second edition of Industrial Cybersecurity. Over the next 24 chapters, we will discuss the next logical steps after building a secure Industrial Control System (ICS) environment and defining a comprehensive set of policies, procedures, and standards, discussed in detail in the first edition.

We are going to start off this second edition with a brief recap of topics and material that were covered in the first edition of Industrial Cybersecurity. This has mainly been added to get you up to speed with the terminologies, technologies, and principles that are expanded upon throughout the rest of this book. The remainder of the book concentrates on security monitoring and verification of the ICS security posture and the various tools, techniques, and activities involved.

This chapter will be a review of the first edition of this book. We will go over all the topics and material that were covered in the first edition, which should give you a solid base for the topics covered in this book. The chapter will conclude with an explanation of what to expect in the rest of this second-edition book.

In this chapter, we'll cover the following topics:

  • What is an ICS?
  • Information Technology (IT) and Operational Technology (OT) convergence and the associated benefits and risks
  • The comprehensive risk management process
  • The Defense-in-Depth (DiD) model
  • ICS security program development
