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.

Red Team versus Blue Team versus pentesting

We briefly discussed the difference between a Red Team exercise and pentesting in Chapter 14, Different Types of Cybersecurity Assessments, but let's look at it from a practical perspective. How do these two assessments differ in practice, as well as how does the Blue Team fit into the grand scheme of things?

Penetration-testing objective – get to the objective at any cost

Typically, penetration tests are time-restricted technical assessments designed to achieve a specific end goal—for example, to steal sensitive data or some secret recipe, to gain Information Technology (IT) or Operational Technology (OT) domain administrator status, to modify a production system, or to grab production data. The TTPs used in penetration-testing exercises are often derived from real-world attacks but are not necessarily developed or designed for the target of the penetrating-test engagement.

Penetration tests should ideally be...
