Dynamic adaptation and reconfiguration of security in mobile devices

Mobile Devices offer enriched services and information for the end users. Achieving security in such a dynamic and heterogeneous environment is a challenging task. Hence, adaptive security is an applicable solution for this challenge. It is able to automatically select security mechanisms and their parameters at runtime in order to preserve the required security level in a changing environment. In this paper, we propose a self-adaptive security solution for Mobile Devices (Smartphone, Tablets,...) based on the combination of the MAPE-K reference model to dynamic negotiate and deploy of security policies, and DSPL approach to reconfigure the security level of the applications at runtime and monitor the changes in the context. The novelty of our approach comes from dynamic negotiation of security policies and automatic reconfiguration of security level to instantiate the new security policies at runtime in order to be capable of deploying adaptive security mechanisms to satisfy different security needs at different conditions.
