I have a Windows (8 Consumer Preview) PC and a Macbook (OS X Lion). Sometimes, I'd want to pause working on a project leave my Windows PC at my room connected to my college's intranet, and keep working somewhere else (in the campus) with the same files, and I don't want the hassle of carrying a USB/uploading to FTP/waiting Dropbox to sync big files etc. so I just want direct access to my project files over the network. However, I'm concerned about the safety of this approach. I've set the sharing settings to my workspace's directory such as: my own account (that I use to log onto my PC) has full access to the files, and I've removed all the permissions (including list dir and read) from the Everyone "user". I can SMB-connect to my PC over the network successfully with my PC credentials and it works perfectly, but is my data (including BOTH my files and my credentials) safe from eavesdropping. The network is completely unsecure (unsecured regular WiFi, just as in a coffee shop) and I need to rely on the safety at a higher layer. Is there any? If not, are there any alternatives (given my requirement previously)?
