Detection of Rogue Access Point to Prevent Evil Twin Attack in Wireless Network

Abstract

From last few years open wireless network commonly available in cafe shop, shopping malls, multiplexes restaurants and other public places to provide free internet service. This open accessible wireless network is vulnerable to different types of threats like eavesdropping, man in the middle attack, evil twin attack, etc. In this paper we consider the problem of open Wi-Fi which is susceptible to Evil Twin Attack created using Rogue Access Point. Evil twin attack is phishing scam in wireless network. Attacker creates rogue access point by spoofing the parameters of legitimate access point to steal confidential information of client and for other malicious activity. We proposed solution to detect Evil Twin Attack dependent on different MAC address and same MAC address as well as same external IP addresses and different external IP address of Access points. Our detection method doesn't rely on network administrator's action. It can easily detect evil twin access point and warns client to disconnect from evil twin access point or alert about existence of evil twin access point if available in wireless network.
