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.

Application security testing

So how do you discover if any of these vulnerabilities are present in the applications deployed on your ICS network? The answer is by testing all of the installed applications for vulnerabilities. And I emphasize all of the installed applications because you first need to know all of the applications that are running on the ICS network. This is where asset management procedures will help. We discussed this in a previous chapter. You cannot secure what you don't know you have. Maintaining an up-to-date asset list with information that includes software versions, patching levels and firmware revisions should be your highest priority.

With an accurate asset list you can compare the revision and patch levels of each application on the ICS network against a list of known vulnerabilities for the application. This process can be done manually or with the help of an automated tool like the previously discussed Nessus scanner or the OpenVAS vulnerability scanner that we...
