1.2 PREVIOUS STUDIES
Several works have affirmed the weakness of Wired Equivalent Privacy (WEP) security algorithm in the original IEEE 802.11 standard and suggested how the security mechanism of WLAN can be enhanced - the paper by Borisov, Goldberg, and D. Wagner, for example, demonstrated the weakness of WEP. There are also few works on how external security apparatus can be used to strengthen the WLAN inbuilt security mechanism – James Burrell and others. This study therefore is undertaken in order to add something new to existing knowledge in the globalised and ever-changing world of technology.
