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.

Red team exercises

A red team exercise is an all-encompassing attack engagement of the organization with the intent to try to gain access to a system by any means necessary. A red team exercise usually includes the following activities:

  • Reconnaissance activities, including public data gathering, Open Source Intelligence (OSINT) gathering, and other publicly available information-gathering activities
  • Cyber penetration testing (trying to get in over the wire)
  • Physical breaching attempt (trying to get in through the front door)
  • Testing for the presence of Plain Old Telephone System (POTS) modem access (war dialing), which is especially valuable in the industrial world where modems are quite often a forgotten access point into the ICS network, installed by an equipment vendor in the 90s and then forgotten about
  • Testing of all wireless and Radio Frequency (RF) systems that are present for potential wireless access (wardriving and RF hacking)
  • Testing of employees...
