I had started to type up what I thought VNC does on login; then I decided to
simply post this link. It should answer any question about security around
the initial authentication:

One thing to keep in mind when using VNC is that even though the inital
authentication may be secure, anything you type while controlling the
computer is sent in plain text. So, if you were to connect to a windows
machine, for example, then login to or unlock the screen on that machine ,
that password you type is sent across the network in the clear.
Or, you type in your password to check your e-mail on that computer; again,
your password is sent in the clear.
I've always recommended tunneling the whole VNC session through some type
of encryption method. (I prefer VPNs)
Actually, I don't think even the initial authentication is secure, you
should definitely use some sort of encryption (ssh or vpn or both)
Personally I'd say ssh is fine when you're connecting from one interior
computer to another, but if you're going to connect from home or something
I'd say tacking a vpn on top would be a good idea.
