Abstract: Wi-Fi protected access 2 (WPA2) is considered one of the most secure protocols employed in wireless local area networks (WLANs). This is despite of having significant security vulnerabilities. The aim of this paper is two-fold. Firstly it analyses the WPA2 security protocol and presents its weaknesses in detail. Secondly it presents a methodology that demonstrates how the WPA2 security protocol can be fully exposed by malicious attacks. Importantly, proposals on how to enhance its security are offered.

Keywords: wireless security; 802.11 security; wifi protected access 2; WPA2 vulnerabilities; WPA; privacy; authentication; wireless LANS; local area networks; WLANs; security protocols; network security; malicious attacks.
