So I was sitting in my room today at the hotel when I opened a Finder window and found on the left side under the "Places" header (I recall it was called that)... a list of computers... some were named, some not... so I clicked thru on them and found that in at least 50% of the case, I was able to literally access someone else's computer... I was browsing their personal files, and a lot of other stuff... it was uncomfortable so I stopped but it caused me to wonder, if I can do it... then can someone do it to me?

How do I insure that this can't happen to me? I'm assuming their was either blue tooth or maybe wifi related?

or?

Most of the time, those are probably Windows computers.

IIRC, by default, a OS X install will only share files in ~/User/Public/ and ~/Shared/

Someone else will know more details, but you should be safe if you keep your files in ~/User/Documents/ or other folders than /Public/ and /Shared/.

Out of the box, your Mac won't share anything over a network.
Go to System Preferences > Sharing to check what you have on, if anything.

That sounds right.

*IF* you turn on Sharing, then by default, only the location mentioned in my post above will be shared.
You can add more to it, if you like. But your home folder and documents will not be shared unless you specifically set it that way.

Your Mac will, however, send out rendevous/bonjour/zeroconf packets. These allow supported services to correlate computer name to an IP address. If your Mac's name is First Last's computer, that will be broadcast throughout the subnet. Same for iphone. Not a concern at home, but perhaps if you're worried about that sort of thing. Change your computer name as it appears in Sharing, and change your iphone as it appears in iTunes, and you'll be ok.

I can understand how it could be a valid concern because of the ease of Mac networking. When I stayed at the Rio in Vegas a few months ago I was able to browse a few different iTunes libraries that were on the local hotel Ethernet network with me. Just make sure you turn off file sharing services you don't want others using when you're on a public LAN and you'll be fine.
