WPA and WPA2 (Wi-Fi Protected Access) is a certification program developed by the Wi-Fi Alliance to indicate compliance with the security protocol created by the Wi-Fi Alliance to secure wireless networks. The Alliance defined the protocol in response to several weaknesses researchers had found in the previous system: Wired Equivalent Privacy (WEP). Many sophisticated authentication and encryption techniques have been embedded into WPA2 but it still facing a lot of challenging situations. In this paper the authors discuss the benefit of WPA2, its vulnerability & weakness. This paper also present solutions or suggestions which will improve Wi-Fi Protected Access 2 (WPA2) protocol.
