The current device-centric protection model against security threats has serious limitations from the final user perspective, among the other the necessity to keep each device updated with the latest security updates and the necessity to replicate all the security polices across all devices. In our model, the protection is decoupled from the users terminals and it is provided through a Trusted Virtual Domain (TVD) instantiated in future edge routers. Each TVD provides unified and homogeneous security for a single user, irrespective of the terminal employed. This paper shows a first prototype implementing this concept through a network element, called Network Edge Device, capable of running the proposed virtualized architecture and making extensive use of SDN technologies, with the aim at providing a uniform security level for the final user.
