Securing the Connected World: Exploring Emerging Threats and Innovative Solutions offers a detailed examination of the growing challenges and cutting-edge solutions in the realms of IoT (Internet of Things) and IoD (Internet of Drones). The book is structured to provide a balanced blend of foundational knowledge and advanced research insights, making it an essential resource for researchers, industry professionals, and students. Covering both established concepts and the latest advancements, it addresses the pressing need for robust security frameworks in today's interconnected digital ecosystems. The first section of the book lays a strong groundwork for understanding IoT security, exploring areas such as attack modelling, intrusion detection, fraud prevention, and secure communication protocols. It also discusses advanced defenses for 5G-powered IoT networks and the integration of Software-Defined Networking (SDN). The second section focuses on IoD, examining critical topics like authentication, trust management, access control, and ethical considerations in drone-based surveillance. By combining theoretical perspectives with practical applications, this book provides a holistic approach to securing the connected world.
