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.

Configuration and change management

The idea behind configuration and change management is that all computer systems enter their life cycle with a baseline: secure configuration. By establishing a known-to-be-secure set of configuration procedures, the baseline, any computer system can start its life with a validated set of secure settings. From that point on, any change to the system configuration and setup will trigger change control procedures that track the changes.

To illustrate, a baseline configuration procedure dictates that a brand new computer system will have its host-based firewall enabled without any firewall exceptions applied. Then, depending on the applications that will run on this system, changes to the baseline configuration might be necessary. For example, when an FTP server is installed, a firewall exception allowing inbound FTP traffic would be necessary. Configuration and change management involves placing procedures around the creation of the baseline configuration...
