The main focus of this module was WLAN security. To secure a WLAN, both
encryption and authentication are necessary. Simply fixing the problems
discovered in WEP is not enough. Wireless networks must authenticate both users
and devices. 802.1x and TKIP provide the necessary security mechanisms to
protect WLANs. VPNs were discussed as another way to successfully secure WLANs.
Through the usage of the hands-on lab activities and the demonstration
activities, students gained a broader understanding of wireless attacks and
countermeasures. Students gained experience in WEP key setup, enabling MAC
filters, and enabling LEAP on AP.
