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.

Threat intelligence explained

Threat intelligence is knowledge, the knowledge of threats that are relevant for your organization and your particular environment. Threat intelligence is the result of a methodical process where evidence-based analysis from a variety of data sources leads to actionable data that can help uncover or eradicate threats that are most likely to be encountered on your network and in your environment. Threat intelligence produces deep insight into adversaries that target your organization, industrial sector, or operational space, and how they perform their malicious Tactics, Techniques, and Procedures (TTPs). This knowledge allows us to make more effective and precise decisions about how we go about securing our environment.

Many so-called threat intelligence sites will try to sell you what they call threat intelligence. By definition, this is not possible. Unless a company is highly familiar with your environment and can perform the process of transforming...
