Internet of Things (IoT) connects sensing devices and physical object/things to the internet for the purpose of exchanging information.Things have become smarter than it was before.IoT enables user to communicate and control smart objects to rescue information that is essential.Massive quantities of data will be generated and exchanged which in turn help in making decisions.However, security and privacy is important while exchanging data from anywhere and at anytime.IoT application protocols based on middleware play a key role in order to facilitate two-way communication and remote control of the IoT devices.Message Queuing Telemetry Transport Protocol (MQTT) is widely used lightweight messaging protocol in IoT.This paper describes security analysis and issues in MQTT protocol by considering different attacking Scenarios.
