The Mechanism and Requirements for Detecting the Cross-Service Attack

The service provided by the mobile device since the network environment becomes with the convergence is varied. The service pattern which personal mobile device provide develops simple individual service into multiple service. In this paper, we consider the threats of the personal mobile devices which support multiple service and multiple communication interfaces such as wireless LAN (WLAN), Code Division Multiple Access (CDMA), Bluetooth, Wireless Broadband (Wibro), Worldwide Interoperability for Microwave Access (WiMAX). Because of supporting various communication interfaces at one mobile device, cross-service attack which doesnpsilat exist in preexistence mobile device appears. The cross-service attack at the multi-functional mobile device generates the fatal problem such as charging and battery consumption unlike the preexistence mobile device to a user. In this paper, we present the detection and the response mechanism for protecting the multi-functional mobile devices against the cross-service attack. We also suggest the security requirements for the multi-functional mobile devices.
