Using a Cable Router and Home networking, how secure am I ?

[cotton]

HI
I just connected three of my computers to a Cable Router. I understand that I can also use the router as a hub and all three computers use the Router to access each other using File and Printer Sharing.
My concern is once I install the FIle and PRinter sharing for all three, can people now access our hard drives through the Router.
If so, what is the best way to have file and printer sharing and still be able to use the router in a secure way.

The default configuration for most routers wont allow any NetBios packets to go out. So you should be safe. If you are using the Netgear RT311 you can go into menu 21 and make sure that filter set 1 is enabled.
