Most applications based on wireless sensor networks (WSNs) nowadays are moving toward the Internet of Things (IoT) paradigm. In order to manage the vast amount of digital resources produced by a large number of heterogeneous devices, the IoT idea is combined with the cloud. A common IoT framework that is interoperable with global infrastructure is much sought for. IoT solutions that need human interaction initially require user identification and permission of access requests made by authorised users. This study provides a plan for creating a general foundation for practical Internet of Things applications. Additionally, it comprises the design and analysis of the two most crucial security modules, access control and authentication, which vary from the security characteristics necessary in a completely automated system. The creation of a general multi-layer architecture serves as the foundation of this study endeavour. Here, the integration of the disparate areas is the key concern (intranet, web, cloud, and application). The layered framework's fine tuning capability makes it possible to add, remove, or modify functions at each horizontal tier, making it capable of meeting the majority of needs of IoT-based remote applications. Here, vertical layers serve as the glue holding together the horizontal layers. The four-layer framework's secured workflow is examined, and remote health scenarios are used to test the framework's viability
