A Survivable Virtual Terminal Based on Environment-Awareness

Now more and more organizations connect to the Internet, accepting the risks along with the benefits. In order to provide sufficient protection against increasingly sophisticated cyber-attacks, survivability technology is explored. For a terminal user, it is very important to construct a survivable workstation. A fine survivable workstation should sense multiple environment factors. To address this problem, we propose a novel Environment-Aware Virtual Terminal (EAVT) solution. It mainly consists of two parts: ERBAC(Environment RBAC) and VT (Virtual Terminal). In our solution, a end-user in Internet can perform his tasks in a VT by the control of ERBAC. Because of VT introduced, all sophisticated actions of user are protected in a close operating environment and go on in security. To illuminate it, we describe the architecture and principle of EAVT and how to implement an EAVT. Especially, we detail the structure of VT, which is the core of our model. Finally, we concluded our work.
