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.

Holistic cybersecurity monitoring

Holistic is defined by the Cambridge English Dictionary as "dealing with or treating the whole of something or someone and not just a part". In the light of cybersecurity monitoring, this means we should leave no stone unturned, no log unchecked, and no system unmonitored. In this chapter, we will see that by combining a variety of security monitoring tools, each geared toward monitoring a certain aspect of the environment, we create a holistic view of the current state of the cybersecurity posture.

Typically, implementing a holistic cybersecurity monitoring program involves applying a combination of several solutions or appliances, distributed over the network or environment they should monitor. For the purpose of this book, we will use a single solution that encompasses an open source variety of each category of these security monitoring applications—namely, Security Onion. We will be expanding Security Onion's functionality...
