Laura,

That you have an open network is surprising. I recently made my Apple 
Airport wireless network 100 times less vulnerable by increasing the 
password complexity. It is easy to establish that first line of defense, 
and I encourage you to do so. Experts here can explain to you the 
additional security features of your Mac, but why not use all of them, 
beginning with a password-protected network?

I see no reason why an iBook would be more or less vulnerable than any 
other model, but perhaps others will enlighten us both on that score.
