Wirelesses Local Area Networks (WLANs) have become more prevalent and are widely deployed and used in many popular places like university campuses, airports, residences, cafes etc. With this growing popularity, the security of wireless network is also very important. In this paper, the authors present the security mechanisms available for WLANs. These security mechanisms are Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA) and 802.11i (WPA2). Their aim is to show how an attack can be made on systems using the above mentioned mechanisms. They have given a brief overview of their working, structure; algorithms used and have tried to explore the real time vulnerabilities by issuing successful attacks against WEP and WPA2 network.
