Industrial Cybersecurity

By: Pascal Ackerman

Overview of this book

With industries expanding, cyber attacks have increased significantly. Understanding your control system’s vulnerabilities and learning techniques to defend critical infrastructure systems from cyber threats is increasingly important. With the help of real-world use cases, this book will teach you the methodologies and security measures necessary to protect critical infrastructure systems and will get you up to speed with identifying unique challenges.Industrial cybersecurity begins by introducing Industrial Control System (ICS) technology, including ICS architectures, communication media, and protocols. This is followed by a presentation on ICS (in) security. After presenting an ICS-related attack scenario, securing of the ICS is discussed, including topics such as network segmentation, defense-in-depth strategies, and protective solutions. Along with practical examples for protecting industrial control systems, this book details security assessments, risk management, and security program development. It also covers essential cybersecurity aspects, such as threat detection and access management. Topics related to endpoint hardening such as monitoring, updating, and anti-malware implementations are also discussed.

ICS security restrictions

Many IT professionals would go about securing an ICS network by extending the process used to secure regular IT resources and networks. This might be applicable to some of the network infrastructure and support services, however many of the core ICS systems and devices do not lend themselves well to following regular IT security strategies. The following are some of the reasons behind this:

  • Device related restrictions: most ICS controls and automation devices are resource restrained. They are small form factor embedded devices with just enough memory and CPU cycles to get their job done. There isn't much room for anything in excess of that.

This prevents the manufacturer from implementing power hungry and resource demanding security controls like authentication or encryption. Apart from being resources restrained, ICS devices have an extremely long lifespan and are often in operation for several decades. Because of their age, they are often fragile, and adding security...
