Fog computing: An overview of IoT applications with security issues and challenges

IoT (The Internet of Things) introduces a revolution into the internet and hardware business, which through sharing information connect one device to another. These IoT devices are connected with a cloud platform for several tasks, including monitoring, categorization, management and control, storage, prediction, etc. Despite all of these features, there is no real-time analysis, in-hour processing and computing, flexibility, interoperability and so on. Fog Computing is an expansion of the cloud to address IoT problems and give a decentralized method. It is connected with cloud as well as end-user to overcome the unsupported features of IoT. These Fog nodes are mobile in nature, connected with multiple local network, local storage can make them more vulnerable where attacker can easily access the information and breach the security. This paper overview the various security issues and real-time applications with possible attacks. Further, we present some of the security challenges and its possible solution. Finally, we conclude the discussion with future research.
