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.

Setting up and configuring Security Onion

Security Onion is an open source Linux distribution aimed at providing intrusion detection, NSM, and log management functionality, all within a single appliance (a virtual machine, or VM). Version 16.04 of Security Onion is based on Ubuntu and contains Snort, Suricata, Zeek, Wazuh, and Squert, along with many other security tools. As of the writing of this book, version 16.04 of Security Onion is being phased out in favor of version 2. The major differences between Security Onion and Security Onion 16.04 include the following:

  • Security Onion 2 features a new web interface called Security Onion Console (SOC) that includes native alert management, threat hunting, and pcap (packet capture file format) retrieval.
  • Security Onion 2 adds TheHive and Strelka support for Sigma rules; Grafana/InfluxDB (independent health monitoring/alerting); Fleet (osquery management); and Playbook (a Detection Playbook tool).
  • Security Onion 2 moves...
