ABSTRACT
The Internet of Things (IoT) has revolutionized various domains, offering connectivity and data sharing among diverse devices and services. However, this interconnectedness poses significant security challenges, primarily centered around confidentiality, integrity, and availability. This paper investigates the security issues embedded in the layers of IoT architecture, ranging from the perception layer to the application layer. By leveraging the Defense-in-Depth security mechanism, we propose a comprehensive approach to fortify IoT systems against cyber threats. The Defense-in-Depth strategy is illustrated through a layered model, addressing security concerns at the perimeter, host, OS/application, and data layers. The study explores various security measures applicable to each layer, emphasizing the need for a multi-faceted approach to ensure the robustness of IoT security.
