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.

Pentesting industrial environments requires caution

So far in this book, we have discussed the potential risk to the ICS environment by performing many active security monitoring activities. Penetration testing is the ultimate active scanning and interrogation activity you can perform on the ICS environment. The assessment has us scanning, probing, poking, fuzzing, attacking, exploiting, and stressing the systems and devices that we agreed on before and are sensitive to this kind of abuse as it is.

As such, we should take extra care when performing the pentest activities on an ICS environment. At a minimum, the production process should be completely stopped, and the right people who can help recover systems and devices when things go wrong should be involved. But more ideally, we should create an approximation of the ICS environment to perform the pentest activities on, or leverage the test environment an organization has, if you are lucky enough to engage a customer with the...
