Title: Detection of Man-In-The-Middle Attack in IEEE 802.11 Networks
Authors: Abdul-Mumin, Salifu
Issue Date: 21-Jul-2011
Abstract: The recent proliferation of high speed wireless portable devices has resulted in a significant demand for wireless LANs. WLANs offer tremendous flexibility to the mobile user, compared with their wired LANs equivalent. With this development, Wireless networks are vulnerable to many identity-based attacks in which a malicious device uses forged MAC addresses to masquerade as a specific client. One of these attacks is Man-in-the-middle attack. Interestingly the man-in-the-middle is usually part of the network where malicious activities are mostly least expected. Most stakeholders turn to secure their networks against unauthorized users paying less attention to those within their own networks. In solving this malicious activity, we studied the state of the act of executing man-in-the-middle attack in wireless networks. Based on this study, a mechanism has been developed to detect this attack. We generated a list of database consisting of IP addresses and MAC addresses of authorized users on a WLAN to check on packets coming to the destination host. The detection mechanism has been simulated in a wireless environment to test the effectiveness of the detection mechanism. In all cases the simulated man-in-the-middle attack was detected. The performance of the proposed detection mechanism was evaluated against an existing detection mechanism.
