Web of Things: Security Challenges and Mechanisms

Web of things (WoT) is an improved and most promising infrastructure of the internet of things (IoT) which permits the smart things to not only integrate to the internet but also to the web. It allows the users to share and create content as well as provide capabilities for data aggregation and analysis through a network to become part of the World Wide Web (W3). Despite these advances, it has shown several security challenges that need to be addressed for the successful deployment of WoT on a commercially variable and large scale. In this paper, authors have analyzed the most noticeable security challenges related to WoT such as unauthorized access, eavesdropping, denial of service attack, tempering, and impersonating, through an analysis of already published empirical studies. Further, we have discussed some of the available mechanisms to overcome security related issues while taking into account the network size and mobility. Authors have used Threat analysis and attack modeling methods to inform the users about defensive measures and to prevent security threats from taking advantage of system flaws Authors have provided the necessary insight into how security can be improved by using certain existing mechanisms and algorithms. The findings of the study revealed that security mechanisms to secure WoT are still immature and future research is required to resolve these challenges.
