In the WLAN you can work comfortably. No matter which room you happen to be when the laptop has a connection, one can easily in the network work. The necessary infrastructure such as access points are cheap and in the standards set up quickly. In principle, provide the access points with WPA, a secure encryption of data traffic. If the wireless access points built into the infrastructure of the IT and administrators know, the risk of compromise is relatively low. Problems to do when employees try yourself, bring up a wireless network and not deny with the administrators. Quick then dangerous half-knowledge is used. For example, since the traffic is not encrypted or not sufficiently or passwords are left at the default settings. These "wild" access points often depend also on the corporate LAN and only permit one access to the Internet and access to shared data. The problem is that wireless networks do not adhere to the limits of the company. Current WLAN products easily create a range of up to 100 meters, walls can limit this, of course. Enough range, then, war drivers to deliver a sufficiently strong signal. You can protect your network by disabling the access points available or integrated into the security structure of the network. But first, the access points are found for now.
