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 6: Passive Security Monitoring

In the previous chapter, we discussed security monitoring in general. We went over the most common ways we can perform security monitoring in our Industrial Control System (ICS) environment—namely, passive and active security monitoring. In this chapter, we are going to take a closer look at passive security monitoring. We will discuss what passively monitoring for security incidents entails, an look at common tools, techniques, activities, and procedures around passive monitoring of the industrial cybersecurity posture. This chapter includes exercises to help you set up a firewall, an ICS-oriented Intrusion Detection System (IDS) solution, and Security Onion. The combination of these three solutions allows holistic coverage of passive security monitoring and will be used throughout the rest of the book in other activities, such as threat-hunting exercises.

We will cover the following topics in this chapter:

  • Passive security...
