Comparative Analysis of Security Issues in the Layered Architecture of IoT

This Unquestionably, Internet of Things (IoT) stands as a novel and more prominent internet based communicating architecture for future applications includes smart cities, smart transportations, smart grid etc. However the most concentrated and research aspect of IoT is security provision to the devices connected and the data transmitting through it. Since the devices communicate through internet in IoT, there exist number of adversaries/ attacks which tries to compromise the network. Herein this leads into the loss of confidentiality, integrity, availability and trust of the devices and network resources. This paper presents a brief survey on the possible attacks happening in different layers of IoT and also presents the possible mitigation schemes to reduce the effect of attacks.
