Abstract
To realize the broad vision of pervasive computing, underpinned by the “Internet of Things” (IoT), it is essential to break down application and technology-based silos and support broad connectivity and data sharing; the cloud being a natural enabler. Work in IoT tends toward the subsystem, often focusing on particular technical concerns or application domains, before offloading data to the cloud. As such, there has been little regard given to the security, privacy, and personal safety risks that arise beyond these subsystems; i.e., from the wide-scale, cross-platform openness that cloud services bring to IoT. In this paper, we focus on security considerations for IoT from the perspectives of cloud tenants, end-users, and cloud providers, in the context of wide-scale IoT proliferation, working across the range of IoT technologies (be they things or entire IoT subsystems). Our contribution is to analyze the current state of cloud-supported IoT to make explicit the security considerations that require further work.
Highlights
During the last decades of the twentieth century there was much research into sensor and communications technologies
It is crucial that the security, privacy and personal safety risks arising from open access to data, across and beyond these systems, are evaluated and addressed
This paper focuses on the security considerations for IoTCloud, given that cloud services act as ‘glue’ that can integrate and mediate ‘things’, as well as provide data processing, storage and management for individual ‘things’
Summary
During the last decades of the twentieth century there was much research into sensor and communications technologies. Personal health and lifestyle monitoring are being integrated with general healthcare services [5] Such application scenarios tend to be sensor/actuator-based, each developed for a single purpose. Many IoT-enabled services are developed with a single application in mind, with little consideration of security issues beyond local concerns, e.g. security might exist within a sensor network, but not when data is passed outside. This paper focuses on the security considerations for IoTCloud, given that cloud services act as ‘glue’ that can integrate and mediate ‘things’, as well as provide data processing, storage and management for individual ‘things’. We begin by providing background and establishing the context for these considerations
