Security in Tiger

She is running OSX 10.4.11 on an iBook and has a Belkin [54g] wireless Router.
She is anxious that her internet connection is without any security - her neighbors tell her they can see her signal. She is not clear if they can log on to it or not.
I now have Leopard and can't remember how we might find out & am no longer able to dig around in my own machine to find out where the information is.
Can anyone help me to advise her please?
