Wireless networks can provide an unintended open door to your network. Unless a valid reason exists for wireless network use, it is recommended that all wireless networks be disabled. If a wireless network is to be used for legitimate purposes, it is recommended that wireless networks be secured as follows: Change the wireless network hardware (router / access point) administrative password from the factory default to a complex password. Save the password in a secure location as it will be needed to make future changes to the device. Disable remote administration of the wireless network hardware (router / access point). If possible, disable broadcasting the network SSID. If your device offers WPA encryption, secure your wireless network by enabling WPA encryption of the wireless network. If your device does not support WPA encryption, enable WEP encryption. If only known computers will access the wireless network, consider enabling MAC filtering on the network hardware. Every computer network card is assigned a unique MAC address. MAC filtering will only allow computers with permitted MAC addresses access to the wireless network.
