Get rid of default settings!

Most wireless devices are being sold today with default configurations that are easily exploited. The three main areas to watch out for are the router administration passwords, SSID broadcasting, and the channel used to broadcast the signal. The default router passwords can easily be changed.

Turning off the SSID broadcast option will prevent unintentional wireless hijacking because rogue wireless devices will not be able to automatically detect the SSID without extra action. Changing the default broadcasting channel will also make a WLAN more unique in its architecture and thus less difficult to detect based on default vulnerabilities.
