Hi Kilawa,

Wireless networks are no more unsecure then any other traditional network when transporting data.

You normally use tcp/ip on it and it is the same standard as when using coax/utp(tp) networks cabling.

As you have noted, the biggest difference here is the possibility of someone not in your office to use your network.

When using the normal (cabling) network someone breaking in or "listening" to your network traffic must get into the building and get access to the cabling, hardware or a connection point into your network.

With the wireless network anyone inside the transmition range of the network can connect and use it, unless to make sure they can't!

So, always the best "encryption" offered by your wireless equipment. Be sure to create a zone in the configuration (to wich all user must belong, by setting it in their configuration) and if there are a reasonable amount of mobile equipment walking around, hard code the access allowed to the net on the mac (hardware) addresses of each nic (network card).

Ontop of this are there "real" security measurements you can make if you handle more sensitive information on your network.

But running it out of the box is not something one should do!
