Intrusion detection and tolerance for transaction based applications in wireless environments

Nowadays, many intrusion detection and tolerance systems have been proposed in order to detect attacks in both wired and wireless networks. Even if these solutions have shown some efficiency by detecting a set of complex attacks in wireless environments, they are unable to detect attacks using transaction based traffic in wireless environments. In this context, we propose an intrusion detection and tolerance scheme that is able to monitor heterogeneous traffic and to detect and tolerate attacks targeting transaction based applications interoperating in wireless environments. A case study is given to illustrate the proposed system capabilities against a complex attack scenario targeting a multi-player wireless gaming service.
