Is hiding SSID good for security?
Hiding SSID is fairly limited as far as security goes. It will make your WAP “invisible” to a degree to your neighbours and other people who might innocently discover your wireless network and connect out of curiosity but it is quite easy to work around for someone with a moderate amount of knowledge using readily available tools such as Netstumbler or by using the rogue Access Point method. There’s also evidence to suggest that hiding SSID might degrade network performance so all in all there’s probably very little to be gained in hiding it.
