Author Description

In a world increasingly threatened by cyber-attacks, "Securing Operational Technology: A Comprehensive Guide to Implementing the Purdue Model" serves as a pivotal resource for any professional involved in protecting our critical infrastructures. This book bridges the divide between information technology (IT) and operational technology (OT), introducing readers to the nuances that distinguish the two, and the imperative need for tailored cybersecurity solutions for OT systems. "Securing Operational Technology" presents an in-depth exploration of the Purdue Model, an essential framework that categorises OT systems into six distinctive levels. Each level, ranging from the sensory and actuating elements to enterprise resource planning systems, is meticulously dissected, with its unique security needs and control requirements detailed. Beyond the mere theoretical presentation, the book offers a prescriptive approach, furnishing readers with a roadmap to secure each layer of the OT environment. This intricate guide is rooted in the principle of defence-in-depth, advocating for the deployment of multiple security controls to construct a robust fortress against a spectrum of cyber threats. The book also illuminates the indispensable role of collaboration between IT and OT teams, emphasising how synergy between the two can lead to a comprehensive understanding of vulnerabilities and the implementation of effective security measures. Moreover, it explores real-world scenarios, providing examples such as the secure remote access via cloud platforms or the configuration of Programmable Logic Controllers (PLCs) by remote vendor support. These practical instances transform abstract concepts into tangible solutions, fostering a more profound understanding of the subject. As a resource, "Securing Operational Technology" stands as a beacon for process control engineers, students, technology professionals, and cybersecurity experts, demystifying the intr
