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 15: Industrial Control System Risk Assessments

In this chapter, we are going to get into the details of Industrial Control System (ICS) risk assessments. We will start the chapter off with a short discussion of how objectives and approaches differ between Information Technology (IT) and ICS cyber attacks. After that, we will explore the different approaches and techniques behind IT system risk assessments before we look at the added complexity of conducting ICS-specific assessments. At the end of this chapter, you should have a good understanding of what is involved in conducting ICS-specific risk assessments.

We will cover the following topics in this chapter:

  • Understanding the attack stages and ultimate objectives of ICS cyber attacks
  • Risk assessments
  • Asset identification
  • System characterization
  • Vulnerability identification
  • Threat modeling
  • Risk calculation
  • Risk mitigation prioritization
