Why can I access my entire mac on my network from another mac?

[lamerica80]

I have a mac mini as my main computer. Connected to my wifi network is another mac i only use for music production.

I have no folders shared on my main computer. Still, under "shared" in finder on my music computer i still see myname:s computer, if i click on that i can access my entire main computer from the music computer.

This worries me as i feel if someone hacks into my wifi network they would have access to my entire computer!!

Please help if you can!
cheers

That's probably because you're using the same account credentials (username and password) on both machines. If you're logged into the same account, you have access to all of the resources allocated to that account. I doubt anyone else can see your stuff.
