A new approach to investigate IoT threats based on a four layer model

This paper is a first attempt to define a set of security vulnerabilities for the Internet of Things (IoT), in a corporate environment, in order to classify various connected objects based on a taxonomy that was previously proposed. The IoT is a complex infrastructure that we divide in four parts (objects, transport, storage, interfaces). It needs protection and supervision. The object and its ecosystem are surrounded with other devices that can become entry points or targets of attacks, even if they are protected from the outer world but not from their local environment. We study the impact of attacks (such as OS reprogramming that has been recently published) on connected thermostats and their possible consequences on their environment, as a first approach to a threat analysis for the IoT.
