Through the use of IP connectivity, the Internet of Things (IoT) offers up new possibilities for automated processes. Things, or devices, are everything from our daily lives that have been upgraded with computing or communication capabilities and are the focus of the Internet of Things. Because Zigbee communication uses a modest data rate and little power compared to other mobile communications, it is frequently employed in controlling or monitoring applications. The research community has focused mostly on securing IoT systems. In order to foresee prospective security threats to the Zigbee protocol, various security threats to Zigbee networks in the IoT platform have been addressed in this article. A Security Improvement Framework (SIF) has also been created for intelligent monitoring in an office or corporate setting. Our suggested SIF can foresee and defend against a variety of potential harmful attacks in the Zigbee network and react accordingly by notifying the system administrator. On the basis of real-time data that the system administrator defines, this framework (SIF) is intended to make automatic decisions right away. As a case study for real-time monitoring, the planned SIF has finally been integrated in a workplace security system. This workplace security system is rated according on its ability to identify potential security threats. According to the evaluation findings, the suggested SIF may effectively identify and defend against a variety of potential security intrusions, enabling more secure intelligent monitoring on the IoT platform.
