Hidden SSID's

What are your thoughts on hidden SSID in a environment? Recently I have been told they are pointless because if someone wanted to hack it they could easily with a sniffer. My reply would be that it at least doesn't give people any idea's trying to connect to it.

 

Any input would be great here

 

Thanks,

Agreed, they are pointless and shouldn't be use in an enterprise environment.

Re: Hidden SSID's

Hidden SSIDs aren't really 'hidden', the ESSID is passed in the clear over the air whenever a client associates. The PROBLEM with Hidden SSIDs is that clients have to probe for that specific SSID before the AP will respond, and some clients may not probe correctly, and this results in huge roaming and performance issues as they spend more time probing in the air than associating. When the SSID is not hidden, clients can see the beacons and probe responses in the air and build a roaming table faster and thus client roaming performance is much improved. 

 

So yes, hiding the SSID is not only pointless, but it also impairs network performance and thus should NEVER be used.
