Q

Disabling SSID to secure a WLAN

Is it possible just to disable the SSID broadcast to secure a wireless LAN? By doing this, you eliminate the finding of your network with tools like Netstumbler.


SSID is the Service Set ID, which is used to identify the particular wireless LAN to be accessed. On many wireless LAN access point devices, it is possible to disable SSID broadcast. In fact, it is a good security idea to change the SSID from the default and to disable the broadcast. This does block tools like Netstumbler from finding your LAN. However, this alone does not make your wireless LAN totally secure. You should use some form of VPN for your connections between client and access point in order to ensure secure communications.

A good reference paper is Security and the 802.11b Wireless LAN, written by Sean Griffin and posted on the SANS Institute site.
