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 5: Introduction to Security Monitoring

Up until now, we have discussed proper industrial control system (ICS) network architecture design and how to build the ICS infrastructure with security, resilience, and uptime in mind. Introduced in the previous chapter, we will be looking at how we can add visibility to the overall ICS cybersecurity posture with the help of security monitoring tools, techniques, and activities. In the second part of this book, we will examine the many facets of security monitoring. We will define the three main methods of security monitoring—namely, passive/active security monitoring and threat hunting. We will see the methodologies behind the three types, as well as play with example tools and techniques, and see how results or findings can be stored, displayed, and scrutinized to find misconfigured controls, eliminate performance hogs, and detect malicious actors and many more security secrets that might be hiding in your environment at this...
