Contemporary Approaches to Enhancing Security in the IoT Ecosystem

Abstract

This article addresses critical security challenges within the Internet of Things (IoT) ecosystem and highlights the capabilities of Microsoft Azure Sphere as a robust platform for safeguarding IoT devices. The study synthesizes contemporary security approaches, including Zero Trust architecture, Cybersecurity Mesh, blockchain-based identity management, and Physically Unclonable Function (PUF) technologies, to enhance both the resilience and scalability of IoT infrastructures. The findings demonstrate that integrating Azure Sphere with Azure IoT Central streamlines device security management while enabling comprehensive data monitoring and real-time operational analytics. Overall, the analysis underscores that the future of IoT security depends on an integrated framework combining artificial intelligence, cloud services, and next-generation authentication mechanisms, thereby providing a holistic strategy for securing complex, large-scale IoT deployments.
