VNC and encryption

[Andrew van der Stock]

If you are concerned about data between devices, you need to use a transport
layer encryption mechanism, like IPsec, ssh or similar. With compression,
the data at least becomes obscured, but things like Ethereal can reassemble
streams if they have a plug-in developed for the purpose.

I understand that VNC encrypts userid and password, but not the data.

Are the data communicating between VNC server and client mainly key strokes,
mouse strokes and screen display?  (Are NT login data (id and password)
travelling alone the cable too?)

If the above statement is correct, is it important for the key strokes,
mouse strokes and screen display to be encrypted?

How about if these traffic are initiating from internal network to the DMZ.
Can it be "cracked" easily?

Any pointers are appreciated.

Thanks,

Dave
