Analysis of Threats for Web of Things (WoT) System

Abstract

Abstract The Web of Things (WoT) emerges from applying Web technologies to the Internet of Things (IoT) to access information and services of physical objects. These systems are likely to characterize the future of digital environment and they put certain security issues in the story. In order to help detect potential threats to WoT-system that is being built and designed, it is advisory to implement a threat modelling process. Threat modelling is an engineering technique that can be used to identify threats, attacks, vulnerabilities and appropriate countermeasures in the context of a particular application and is a process best implemented at the system design stage. In this paper, we will analyse the threats for WoT-based door management system by using Microsoft Threat Modeling Tool (MTMT) in order to identify potential threats for this system in design phase. Obtained results justified the use of threat modelling in the design phase given that we have identified in total 89 threats, with Elevation of privilege and Denial of Service (DoS) being the most prominent ones. Those threats are characterized as high and medium risk ones.
