Internet of Things: Proposed security aspects for digitizing the world

The Internet is a Heterogeneous entity which is constantly changing and evolving. The concept of “Internet of Things” (IOT) refers to extending the intelligent sensors in our day to day objects such as televisions, fridge, media players, heating appliances etc. This would help in extending the ability of the objects to provide feedback to the user. This enables the object to have some sort of consciousness. What we have today is the human interacting with the object and not vice-versa, but the IOT would help us to complete this loop. This kind of digitization would mean that our next generation of refrigerators would know more about our diet then our current dieticians. This would help in creating a “system of systems”. Considering a current scenario where the number of digital security threats and attacks are increasing day by day, the notion of IOT would be incomplete if we ignore its security aspects. In this paper, we would be exploring the various security aspects of IOT such as security of remote frequency identifiers(RFID), wireless sensors etc. We have proposed a taxonomy of the security aspects of IOT. We have also explained the basic concepts and motivation behind the evolution of IOT, its architecture, and applications.
