Just banning wireless is not solve problem. Security have to be transparent for end user, not to put chains on his hand.
Wireless LANs (WLANs) are increasingly becoming a commodity in the home, in the high street, at the airport – everywhere but in the office it seems. This is because it is still considered a threat to corporate data security – risking data loss, information theft, and virus and worm infection. As a result, despite increasing demands from users for wireless connectivity in the office, many organizations still implement a strict “no wireless” policy. For these organizations, the perceived risk of breaching the established ‘perimeter security’ architecture of the wired LAN by building WLANs is far greater than the mobility and flexibility benefits of the technology.
