In their delivered state, WLAN components are often configured with only a few security mechanisms activated (or none at all). Some of these mechanisms are also insufficient and therefore fail to offer adequate protection. Even today, various WLAN components are still used that only support inadequate security mechanisms such as WEP. In some cases, these devices cannot even be updated with stronger security mechanisms. If such devices are used, an attacker might easily eavesdrop on all communications and thereby obtain confidential information.
