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.

Security monitoring

Now that we have beaten the network architecture discussion to death, it is time to look at how to tackle what, in my opinion, is the second-most effective method to improve the ICS security posture: security monitoring.

Security monitoring comprises all the tools, techniques, activities, and actions involved in verifying the effectiveness of a security program. Security monitoring includes topics such as log monitoring, configuration verification, alert visualization, passive and active network scanning/mapping, vulnerability management, Intrusion Detection Systems (IDSes), Security Information and Event Management (SIEM), and so on.

The many aspects of security monitoring are the main topics of this book and will be explained in depth throughout the remaining chapters. What follows is a discussion on how the designing for security architecture we covered in the previous sections is used to set up the tools and systems that allow us to implement security...
