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.

Risk assessments


The business dictionary defines risk assessment as:

"The identification, evaluation, and estimation of the levels of risks involved in a situation, their comparison against benchmarks or standards, and determination of an acceptable level of risk."

In other words, risk assessments are about discovering everything that could potentially go wrong with a particular situation such as the specific setup and configuration of a system. By discovering the flaws or vulnerabilities of that system, the possibility of something going wrong and the potential impact of the occurrence can be determined. Given that explanation, let’s look at a definition of risk. The authors of the book Hacking Exposed Industrial Control Systems: ICS and SCADA Security Secrets & Solutions by Clint Bodungen, Bryan Singer, Aaron Shbeeb, Kyle Wilhoit, Stephen Hilt, give the most complete description of risk I have encountered:

“Risk is the likelihood that a threat source will cause a threat event, by means...
