A WTLS-based virtual private network for wireless intrusion prevention

It is well known that virtual private network (VPN) and intrusion prevention system (IPS) are all important network security schemes. Traditionally, both VPN and IPS need a clear network margin. However, now the rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security. It is a noteworthy problem how to display wireless IPS (WIPS). Because of some characteristics of wireless network, it is not so convenient to build a WIPS in wireless environment as in wire environment. To address this problems, this paper explorer a novel wireless VPN: WBVPN(WTLS-Based VPN). In WBVPN, a logical sole path is built between wireless terminal and its destination, so a IPS engine can detect and prevent the traffics of user. WTLS is introduced firstly and then by WTLS-VPN, we give a basic solution of intrusion prevention in wireless network. Besides, an access control mechanism which have been and an access control mechanism in our former work is applied to WBVPN. Finally, an experiment about performance of WBVPN will be displayed.
