In the recent times, the outburst of embedded and connected smart devices and systems has created an opportunity to connect every ‘thing’ to the internet.In this regard the Internet of Things(IoT) is one of the most hyped- set of technologies and a system of interconnected devices, both mechanical and digital machines, electronics, software, sensors, objects, animals or humans that are given a unique identifier and the ability to transfer data over a network without requiring ‘human-to-human’ or ‘human-to-computer’ interaction.An IoT system consists of sensors/devices which “talk” to the cloud through some kind of connectivity and based on the processing of software it then automatically adjusts without the need for the user. The extensive set of applications for IoT devices include consumer applications, smart home, enterprise applications, infrastructure applications etc. If we look at the recent trend, we can clearly observe a significant trend in the explosive growth of devices connected and controlled by the internet thus automating maximum tasks in business enterprises and promising new jobs, where people can understand and leverage the IoT to create solutions that will be greatly in demand. However IoT has been criticized on several grounds such as insecure implementation, a significant and variable lag into the control loop introducing instability and an exposure of vulnerabilities that might be exploited by hackers.
