Evaluating Critical Security Issues of the IoT World: Present and Future Challenges

TLDR

The Social Internet of Things merges IoT with social networks, enabling device interaction and information sharing, but its limited resources, heterogeneous technologies, and lack of dedicated standards create a fertile ground for security and privacy vulnerabilities. This study aims to organize the IoT security landscape by providing a taxonomic analysis of perception, transportation, and application layers and highlighting the most critical issues to guide future research. The authors conduct a taxonomic analysis across the perception, transportation, and application layers of the IoT system model to identify and classify security threats.

Abstract

Social Internet of Things (SIoT) is a new paradigm where Internet of Things (IoT) merges with social networks, allowing people and devices to interact, and facilitating information sharing. However, security and privacy issues are a great challenge for IoT but they are also enabling factors to create a "trust ecosystem." In fact, 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. In this paper, we try to bring order on the IoT security panorama providing a taxonomic analysis from the perspective of the three main key layers of the IoT system model: 1) perception; 2) transportation; and 3) application levels. As a result of the analysis, we will highlight the most critical issues with the aim of guiding future research directions.
