Investigation of Access Control for Internet of Things: Service-Level Role-Based Access Control
Janani Janardhanan, Mehrdad S. Sharbaf · 2017
Internet of Things (IoT) is basically a system of inter-related computing devices on a network which perform data collection and exchange of real world properties. The major developments witnessed in IoT are mainly within companies, industries, a home environment etc. To increase the scalability of IoT, various security concerns need to be overcome. IoT devices are mostly resource constrained. Complicated network produces potential vulnerabilities referred to heterogeneous devices, sensors and backend systems. So, to realize the dream of internet of things, security is to be ensured for device to device communication. Though IoT has security mechanisms at the network and device level through identification management, it is safer to have a per-service level specific access control based on the “Roles of Things” to attribute for confidentiality and Integrity. This paper presents the current security practices and puts forth the future scope of improvement in fine tuning service level access control.
