Securing the IoT world: Issues and perspectives

In the next future, IoT systems will be 'ubiquitous' and 'pervasive', bringing several benefits to mankind and also many issues about interoperability, security and privacy. The intrinsic vulnerabilities of IoT devices, with limited resources and heterogeneous technologies, together with the lack of specifically designed IoT standards, represent a fertile ground for the expansion of specific cyber threats. Consequently, security and privacy issues have become a great challenge in the IoT topic. In this paper we try to bring order on the IoT security panorama providing a taxonomical analysis from the perspective of the three main key layers of the IoT system model: Perception, Transportation and Application levels. As a result of the analysis, we will highlight the most critical issues with the aim of guiding future research directions.
