Through real case studies on the organisations with various security measures and by showing complete execution paths of our framework, we suggest the importance of continual assessment of the WLAn for strong corporate security assurance using our Corporate WLAN Security Assessment Framework Keywords: Wireless Local Area Network(WLAN); corporate wireless LAN wireless LAN assessment framework: wireless information Privacy(WEP): WiFi Protected Access(WPA) Virtual Private N;802.11b;802.1li.
