Application of VPN Based on L2TP and User’s Access Rights in Campus Network

VPN is widely used in colleges and universities at present, having brought great convenience to teachers and students in their study and life. Due to the fact that the current VPN in colleges and universities has the same access rights to all users, as long as VPN users login successfully via VPN account, they can access the campus network. As a result, not only is the management of the VPN administrators troublesome, but also the security of the network environment in the school is not very good. In view of this problem, this paper proposes a method that people visit the campus network resources according to user’s access authority in which the distribution of access rights can be distributed according to user’s identity category or individual way, and gives the application in college campus network. Finally, the simulation results show that this system is feasible to guarantee the security of communication.
