Internet of Things (IoT) basically discusses about the connection of various physical devices through a network
and let them take an active part by exchanging information through Internet. This paper presents important
applications of IoT and the different challenges of IoT. Out of the various challenges, attacks on the devices used
in IoT are of serious concern. Device oriented attacks and the defensive mechanisms are studied in this paper. A
comparison is done for the specific malicious attacks on the M2M communicating devices.
Keywords: - Applications, Challenges, Device oriented security challenges, M2M Communicating devices, Security
