Abstract
Wireless Local Area Networks (WLANs) are increasingly integrated into our daily lives. Access Points (APs) are an integral part of the WLAN infrastructure, as they are responsible for coordinating wireless users and connecting them to the wired side of the network and, eventually, to the Internet. APs are deployed everywhere, from airports and shopping malls to coffee shops and hospitals, to provide Internet connectivity. One of the most serious security problems encountered by WLAN users is the existence of Rogue Access Points (RAPs). This article classifies existing solutions, identifies vulnerabilities, and suggests future directions for research into these RAPs. The ultimate objective is to classify existing detection techniques and find new RAP types that have not been classified by the research community. The literature typically categorizes Evil-twin, Unauthorized, Compromised, and Improperly Configured RAPs. Two other types have largely been abandoned by researchers, but can be classified as Denial of Service RAP attacks. These are deauthentication/disassociation attacks targeting wireless users, and the forging of the first message in a four-way handshake.
