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 processes

There are two distinct aspects to incident response:

  • Incident response preparation
  • Incident response handling

The incident response preparation process occurs periodically without any identified incident. The incident handling process is triggered when an incident is detected.

Incident response preparation process

The goal of the preparation phase of incident response is to prepare the Industrial Control System (ICS) or OT security team to handle incidents efficiently and effectively. By its nature, the preparation phase occurs separately from any identified incident or event.

Creating and maintaining an incident response policy document (we want to record and track our IR processes and procedures), and the related processes and procedures documents, is at the heart of the preparation phase. The incident response preparation process includes both tasks intended to help prevent incidents and tasks intended to streamline incident...
