| Abstract | With the increasing dependence on wireless LANs (WLANs), businesses, educational institutions and other organizations are in need of a reliable security mechanism. The latest security protocol, the IEEE 802.11i assures rigid security for WLANs with the support of IEEE 802.1x protocol for authentication, authorization and key distribution. Nevertheless, fresh security threats are emerging often to oust these new defense mechanisms. Further, many organizations based on superficial vendor literature, believe their wireless security is sufficient enough to prevent any unauthorized access. Having wide ranging options for security configurations, users are camouflaged into deep uncertainty. This volatile state of affairs has prevented many organizations from fully deploying WLANs for their secure communication needs, though WLANs may be cost effective and flexible. In this paper, we present a novel mechanism to detect and substantiate anomalies caused by both known and unknown security threats in WLANs. We monitor the wireless environment for timing and/or behavior anomalies during the security association process and use outlier based data association approaches to substantiate their legitimacy. The proposed concept was tested on our experimental setup. The results obtained from wireless hosts configured for EAP-LEAP, PEAP and TLS security association show high confidence for EAP group events. |
