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.

Details about the industrial environment – lab setup

Let's look at the industrial environment part of the lab architecture:

Figure 19.4 – Lab architecture – industrial network

Here, we can see that the network is split into two enclaves, separated by the Operational Technology (OT) firewall. The controls and automation devices are a mix of physical hardware and VMs. All the VMs will be running on the Dell ESXi server for the industrial environment, including the Security Onion and SilentDefense appliances (see the Packet capturing and passive security tools section for details). We will use a single vSwitch with multiple virtual port groups (VLANs) to create a separation between the Level 3 Site Operations enclave and the process network. The OT firewall (pfSense) is configured with three virtual NIC cards to connect to the Level 3 Site Operations VLAN, the process network VLAN, and the Cisco 3750 enterprise switch. Finally, we...
