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.

The ICS is extremely defendable

By nature ICS are very defendable. Because ICS systems tend to be stagnant in configuration it is easier to detect anomalies. For example, it is relatively easy to establish a standard traffic pattern on a controls network and start looking for deviations from normal. Also, because ICS don't change very often, the environment they are in is easier to secure. An example to that point is that a PLC can be placed in a locked cabinet with it's program locked into run mode, because once a PLC is running changes are hardly ever necessary. If changes are needed, a change control program should secure the proper management of those changes.

So on one hand an ICS is horribly defenseless because restrictions and requirements don't allow for traditional security practices to be applied. On the other hand the very nature of an ICS makes it extremely defendable. Only by choosing our battles and implementing security controls where we can and filling the gaps by applying...
