Towards a reference ontology for security in the Internet of Things

The diversity of wireless technologies, connected to the Internet and the more powerful and smaller embedded devices, allows to encompass services to improve everyday activities around us through new applications and businesses. This context emerged with the Internet of Things (IoT), where different technologies connected with the Internet provide several applications to change people's lifestyle. However, such integration of heterogeneous devices causes many problems of security and privacy due vulnerabilities of technologies, carrying important consequences to the users of IoT technologies. In this context, we proposed a reference ontology (IoTSec) with security concepts of M2M communications to help find secure solutions to the IoT environment. We followed a literature review and MENTOR methodology to gather and harmonize security ontologies and knowledge of vulnerabilities, which are the root causes for problems of all information security. In order to elucidate our approach, we describe a case study about the applicability of IoTSec in the industrial scenario.
