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.

Incident response procedures

The SANS Institute describes a six-step incident handling process, as shown in the following diagram. The first step, Preparation, corresponds to incident response preparation processes and procedures, while the other five steps (Identification, Containment, Eradication, Recovery, and Lessons Learned) correspond to incident handling processes and procedures:

The following procedures provide more details about how the steps in each of the process flows are to be accomplished. Because of the diverse nature of incidents, the procedures do not attempt to give step-by-step instructions but rather focus on a methodology to organize effort, manage resources, and communicate about incidents to stakeholders.
