Big Data Analytics as a Solution for Threat Analysis and Risk Mitigation in Smart Cities: a Review

Abstract

We have addressed the issues of urban public and the city improvement cleverly, the utilization of IoT gadgets, for example, sensors, actuators, and cell phones, and so forth. The brilliant framework is the quick and important source. In any case, interconnecting a huge number of IoT gadgets while speaking with each other over the Internet to build up a savvy framework brings about the era of gigantic measure of information, named as Big Data. While coordinating IoT benefits it should be kept in mind the end goal is to get continuous city information and after that preparing such enormous measure of information in a productive route we went for setting up keen city was a testing undertaking. We have reviewed the different-different papers like utilizing big data analytics as a solution for smart cities and threat modelling for smart city infrastructure. It states the data privacy in smart cities which are using sensors to access the data. It focused on state-of-the-art proposals for development that continues in enhancing big data analytics performance and smart cities adaptations and the possibilities are limitless. Pros and cons of actual research efforts along with future research directions are to be considered in future years. In data Security and threat modelling for smart city infrastructure paper, we look into security issues in smart city infrastructure from both technical and business operation perspectives and proposed an approach to analyse threats and to improve data security of smart city systems.
