Analysis of security issues and their solutions in wireless LAN

This paper begins by introducing the concept of wireless LAN (WLAN). The introductory section gives brief information on the WLAN components and its architecture. In order to examine the WLAN security threats, this paper will look at both active & passive attacks. The paper will then explain the security & flaws of legacy IEEE802.11 WLAN standards. This situation leads to further research regarding practical solutions in implementing a more secured WLAN. This paper will also cover the new standards to improve the security of WLAN such as the IEEE 802. lx standard, which comprises of three separated sections: Point-to-Point Protocol (PPP), Extensible Authentication Protocol (EAP) and 802. lx itself. Then the paper look for a newly proposed standard i.e. 802.11Î for key distribution and encryption that will play a big role in improving the overall security capabilities of current and future WLAN networks. Finally, this paper ends with the conclusion of highlighted issues and solutions.
