RE: VNC over VPN, security considerations?

As usual, the answer is:  It depends.
 
In this case, mostly on how paranoid you are.  If you trust the non-VPN
parts of the communication path, then you probably don't need to worry much
more about it.  Here's what the FAQ has to say about it:

I run VNC over an SSH connection (that requires RSA keypair login) and I
sleep well at night.

Subject: [VPN] VNC over VPN, security considerations?




        Hello, 

        Well again normally I just sit back and read what you all have to
say, but I've 
        got another question. For the most part our VPN is up and functional
without 
        anything more for me to do except load the cisco client software on
to the 
        machines of the converts. Recently however I have been looking at
uses I could 
        have for the VPN aside from answering my Emails on my days off. 

        One of the software products I use on occasion is VNC for remote
control access 
        and installs of patches, and the like. It looks as if when I do a
search for ports 
        and VNC I get as many hits telling me that ports 5800 and
5900+display# are the 
        ones used as I get "VNC port firewall, viren, hackertools, and
exploits." This does 
        not give me a warm fuzzy about opening those ports so that I could
use VNC 
        over the VPN. 

        So my question is simply: "What are the considerations and
mitigating steps 
        that I could take if we decided to open these ports up? Or...is it
simply a very 
        bad idea? 

        Thanks for your time. I'll go back to reading for the most part
again.
