The Internet of Things (IoT) is the Internet's latest innovation today, where every physical object is situated or where measurement, as well as communication capacities, can be seamlessly synchronized to the Internet at various rates. The most important infrastructure, the smart grid, is called the extended version of the power grid with comprehensive Internet infrastructure. The smart grid will include billions of intelligent appliances: intelligent meters, actuators, vehicles and so on, despite a few correspondence infrastructures, whether public or private. Notwithstanding, security is viewed as one of the primary considerations hampering the large scope reception and arrangement of both the IoT vision and the smart grid. To date, the issues of IoT for the smart grid are rarely discussed empirically in any academic research. This study aims to examine security problems and challenges in the IoT smart grid system. Findings show various issues that we can categorize into three parts; component issues, system issues and network issues. As a result, this study proposes a mitigation plan for the problems highlighted by developing an IoT smart grid security component model.
