"Critical infrastructure sectors are those whose assets, systems, and networks, whether physical or virtual, are deemed so important to nations that their incapacitation or destruction would have a crippling effect on national security, national economic security, national public health or safety, or any combination of these. Each country might define their unique critical infrastructure. In this book, we compiled nine critical infrastructure sectors: Emergency Services, Energy, Finance, Food, Government, Health, Telecommunications, Transport, and Water. The continuity of services in these sectors is vital for the daily lives of societies and economies. This study introduces 49 case studies from various parts of the world. This book investigates Cyber Resilience in Critical Infrastructure by paying attention to recommending a national-level cyber resilience framework for all nations to use. Furthermore, we present sectoral analysis and case studies for each infrastructure by going through an in-depth analysis. As military tensions grow in many parts of the world, nations are alarmed and focused on their national cyber resilience, especially the reliability of their critical infrastructure. We believe this book will be a popular reference and guidebook for a wide range of readers worldwide, from governments to policymakers, from industry to the finance sector and many others"--
