WBIPS: A Lightweight WTLS-Based Intrusion Prevention Scheme

Now the rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security. The common Intrusion Detection System is not always sufficient and effective for wireless environment. Intrusion Prevention System (IPS) in wireless network need be developed. But because of some characteristics of wireless network, it is not so convenient to build an IPS in wireless environment as in wire environment. To address this problem, we explorer a novel scheme: WBIPS (WTLS-Based IPS) model. In this mode, a logical sole path is built between every wireless terminal and its destination, so an IPS engine can detect and prevent the traffics of user. We will describe the architecture of WBIPS in detail. WTLS (Wireless Transport Layer Security) is introduced firstly and then, we explore a solution of wireless intrusion prevention. Finally, An experiment about performance of WBIPS will be displayed to approve "lightweight" of this model.
