Role of Feature Selection in Intrusion Detection Systems for 802.11 Networks
Intrusion Detection Systems are important for protecting network and its resources from illegal penetration. For 802.11network, the features used for training and testing the intrusion detection systems consist of basic information related to the TCP/IP header, with no considerable attention to the features associated with lower level protocol frames. The resulting detectors were efficient and accurate in detecting network attacks at the network and transport layers, but unfortunately, not capable of detecting 802.11-specific attacks such as deauthentication attacks or MAC layer DoS attack. IDS systems can also identify and alert to the presence of unauthorized MAC addresses on the networks.
