An IEEE 802.11 WLAN is a group of wireless nodes located within a moderate physical area. It provides intensified productivity, less cost of installation and mobility. The open to air nature of wireless channel that give the people great convenience of mobility also make it vulnerable to attack. Various security issues are described in paper. The tradeoff between security and throughput is main focus in WLAN. As if the security increases the throughput gradually decreases. To solve this problem various techniques are used which reduces this problem.
