Although recent advances in technology have made life easier for individuals, societies, and states, they have also led to the emergence of new and different problems in the context of security. In this context, it does not seem possible to analyze the developments in the field of cyber security only with information theft or hacking, especially in the age of artificial intelligence and autonomous weapons. For this reason, the main purpose of this book is to explain the phenomena from a different perspective by addressing artificial intelligence and autonomous weapons, which remain in the background while focusing on cyber security. By addressing these phenomena, the book aims to make the study multidisciplinary and to include authors from different countries and different geographies. The scope and content of the study differs significantly from other books in terms of the issues it addresses and deals with. When we look at the main features of the study, we can say the following:Handles the concept of security within the framework of technological developmentIncludes artificial intelligence and radicalization, which has little place in the literatureEvaluates the phenomenon of cyber espionageProvides an approach to future warsExamines the course of wars within the framework of the Clausewitz trilogyExplores ethical elementsAddresses legal approachesIn this context, the book offers readers a hope as well as a warning about how technology can be used for the public good. Individuals working in government, law enforcement, and technology companies can learn useful lessons from it.
