Live Linux distribution devices can hold Linux operating system for portability. Using such devices and distributions, one can access system or critical files, which otherwise cannot be accessed by guest or any unauthorized user. Events like file leakage before the official announcement. These announcements can vary from mobile companies to software industries. Damages caused by such vulnerabilities can be data theft, data tampering, or permanent deletion of certain records. This study uncovers the security flaws of operating system against live device attacks. For this study, we used live devices with different Linux distributions. Target operating systems are exposed to live device attacks and their behavior is recorded against different Linux distribution. This study also compares the robustness level of different operating system against such attacks.

Internet of Things (IoT) is an evolving research area for the last two decades. The integration of the IoT and social networking concept results in developing an interdisciplinary research area called the Social Internet of Things (SIoT). The SIoT is dominant over the traditional IoT because of its structure, implementation, and operational manageability. In the SIoT, devices interact with each other independently to establish a social relationship for collective goals. To establish trustworthy relationships among the devices significantly improves the interaction in the SIoT and mitigates the phenomenon of risk. The problem is to choose a trustworthy node who is most suitable according to the choice parameters of the node. The best-selected node by one node is not necessarily the most suitable node for other nodes, as the trustworthiness of the node is independent for everyone. We employ some theoretical characterization of the soft-set theory to deal with this kind of decision-making problem. In this paper, we developed a weighted based trustworthiness ranking model by using soft set theory to evaluate the trustworthiness in the SIoT. The purpose of the proposed research is to reduce the risk of fraudulent transactions by identifying the most trusted nodes.
