At our first April meeting, Bob Gray and Dave Clements
discussed security issues around 802.11b-based wireless networks and
Wireless Equivalent Privacy (WEP). Bob and Dave could
barely get a word in edgewise given the level of
interest and number of questions during their talk.
Leaving the audience astonished at how easy it is
to crack wireless network security, and appalled at
the number of networks that don't even turn WEP security
features on at all, Bob and Dave went on to discuss
ways in which you can secure your wireless networks.
Their presentation slides are available here.
