A WTLS-Based Virtual Private Network for Wireless Intrusion Prevention

AbstractIt is well known that virtual private network (VPN)and intrusion prevention system (IPS) are all importantnetwork security schemes. Traditionally, both VPN and IPSneed a clear network margin. However, now the rapidproliferation of wireless networks and mobile computingapplications has changed the landscape of network security. Itis a noteworthy problem how to display wireless IPS (WIPS).Because of some characteristics of wireless network, it is not soconvenient to build a WIPS in wireless environment as in wireenvironment. To address this problems, this paper explorer anovel wireless VPN: WBVPN(WTLS-Based VPN). In WBVPN,a logical sole path is built between wireless terminal and itsdestination , so a IPS engine can detect and prevent the trafficsof user. WTLS is introduced firstly and then by WTLS-VPN,we give a basic solution of intrusion prevention in wirelessnetwork. Besides, an access control mechanism which havebeen and an access control mechanism in our former work isapplied to WBVPN. Finally, an experiment about performanceof WBVPN will be displayed5 Halama
