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.

Chapter 8: Industrial Threat Intelligence

Now that our security monitoring tools are installed, we will start looking at ways we can expand their functionality and extend their capabilities. While in the next chapter, Chapter 9, Visualizing, Correlating, and Alerting, we will look at ways to add visibility, more detailed information, and generally better threat detection functionality, in this chapter, we will discuss the tools, techniques, and activities that allow us to add threat intelligence to our security monitoring programs. Threat intelligence adds confidence of existence, likelihood of compromise, and feasibility of exploitation to our security monitoring solutions by correlating found security monitoring artifacts (such as URLs, IP addresses, and file hashes) to known threat information (indicators of compromise) in a way that makes the resulting information relevant and actionable for our environment.

We will cover the following topics in this chapter:

  • Threat...
