In recent years, the use of the Internet of Things (IoT) has grown rapidly in smart cities, households, and smart industries environments due to the benefits of convenience and easy implementation. The Long-Range Wide Area Network (LoRaWAN) is a key technology driving this growth, which has seen significant adoption due to its scalability, long-range capabilities, low power consumption, lost cost and wide area coverage. As the use of LoRaWAN-enabled IoT environment has increased, the cyber-attacks related to it have also increased. About 95 % of the cyber-attacks in IoT environment occurs due to the security vulnerabilities caused by the user's errors. However, much research in the LoRaWAN environ-ment is highly focused on the security vulnerabilities due to technical errors, leaving gaps in identifying the security vulnerabilities that occur due to user errors. Therefore, this paper addresses these gaps by identifying user-centric errors which may lead to cyber-attacks in an LoRAWAN IoT environment. It builds a taxonomy based on a comprehensive literature review and maps these user errors to potential security vulnerabilities within LoRa WAN- enabled IoT environments.
