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.

What is incident response?

Incident response (IR) is the process by which an organization prepares for and handles a (cyber)security-related incident such as a data breach or cyberattack. This includes efforts taken to manage the fallout/consequences of the incident. The goal of implementing an IR program/process is to be able to effectively manage incidents to the point where the damage and impact of the incident is limited, and both the recovery time and costs, as well as collateral damage, which includes the organization's reputation, are kept to a minimum.

Organizations should invest time and resources in implementing a comprehensive incident response plan that can help them prepare for, and deal with, security incidents. The IR plan should put definitions around what is considered an incident for the organization and provide clear, guided processes and procedures to be followed in case an (OT) security incident occurs.

The following sections detail the two distinct...
