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.

Exercise 3 – Setting up, configuring, and using Forescout's eyeInsight (formerly known as SilentDefense)

The final exercise for this chapter is about building and configuring a Forescout SilentDefense OT/ICS IDS and asset management appliance.

Deploying the SilentDefense sensor and Command Center VMs

The Forescout SilentDefense sensor and Command Center appliances come as downloadable Open Virtual Appliance (OVA) template files and can be downloaded from the Forescout customer portal once you have purchased the product. OVA is a file format that supports the exchange of VMs across various virtualization products and platforms.

For this exercise, I will be using the following two OVA files:

  • sd-411-cc-16g-vmware.ova: This is the 16 GB random-access memory (RAM) version of the Command Center.
  • sd-411-sensor-8g-vmware.ova: This is the 8 GB RAM version of the sensor.

We will be installing the VMs on a vCenter cluster for two reasons, the first being...
