Wi-Fi Security protocols: A survey

Over the years, the wireless technology has evolved significantly and therefore the need to protect the wireless network becomes equally substantial. The choice of the best security protocol has always been an issue for the IT security staff. This paper illustrates various types of security mechanisms of wireless LAN. These security protocols are (802.11 Wired Equivalent Privacy, 802.11i Wi-Fi Protected Access and Wi-Fi Protected Access-2). The paper gives an overview of the key concepts and the working of the wireless security protocols, their limitations and the countermeasures introduced. The three protocols are also compared on the basis of the common features so as to give a deeper insight
