Outsourcing Mobile Security in the Cloud

In order to prevent attacks against smartphones and tablets, dedicated security applications are deployed on the mobile devices themselves. However, these applications may have a significant impact on the device resources. Users may be tempted to uninstall or disable them with the objective of increasing battery lifetime and avoiding configuration operations and updates. In this paper, we propose a new approach for outsourcing mobile security functions as cloud-based services. The outsourced functions are dynamically activated, configured and composed using software-defined networking and virtualization capabilities. We detail also preliminary results and point out future research efforts.
