Does 802.11 provide security implicitly? one can apply WEP (Wireless Equivalency Protocol) to encryption the data, but even that has been shown to be vulnerable (http://www.isaac.cs.berkeley.edu/isaac/wep-faq.html) there are a few alternatives that can be used to make it more secure: [1] deploy a setup whereby one has per-user dynamically-changing WEP keys. details on how one vendor can do this are at: http://www.cisco.com/warp/public/cc/pd/witc/ao350ap/prodlit/1281_pp.htm details on how to actually configure it is at: http://www.cisco.com/univercd/cc/td/doc/product/wireless/airo_350/accsspts/ap350scg/ap350ch3.htm#xtocid586920 [2] don't trust the link layer, and encrypt everything you send. this could be as simplistic as adding MAC-address filters to your access-points and building a tunnel of some kind (eg. IPsec, or even as simplistic as SSH port-forwarding). if one is prone to be paranoia, using both [1] and [2] probably makes sense. cheers, lincoln.
