Check out this link. Item 54 on the FAQ
concerns the security of VNC. Hope this
helps.

Relax it is pretty secure!
It uses mostly tripple DES encryption and that is very secure. You can use VPN from a 3rd party or from 2000 i think!
You also have 2 options...
Box to Box meaning Firewall to Firewall or
Machine to box where you have a firewall and a client machine running the VPN software and usually is a one way connection from the client to the Firewall.
Hope this helps!

Check out the book Hacking Exposed 2nd edition. There is a chapter on remote control software and its vulnerabilities, things to do to secure it.

You can also use NetMeeting to remote control a computer. Security you should do on the firewall close all the ports for a VNC connection exept from known IP address. If you use it from a non static IP address then you will have to rely on the VNC security. If you use it for remote users not control then there is much better ways of doing it than VNC, check out terminal services.

I have used VNC over the net before and I reckon it is Ok to use. I doubt it could be 100% secure unless ur running a firewall and connecting thru sockets. if not then PCAnywhere or other 3rd party software could work. I quite like Laplink Pro and NCDesktop Mirror though laplink also allows file transfer.
End result .... use VNC its free!!
