RE: RDP over the internet

[Dimitrios Hilton <dhilton () theitguy us>]

I agree, that port 3389 has seen a dramatic increase in attacks.

In addition, TS/RDP services running on a server are subject to a Man in the Middle attack because by default, Windows 
fails to provide secure authentication. We are often led to believe that the encrytion alone is enough, but that does 
not provide sufficient security with either the old or new version of RDP client that ships with most versions of 
windows.

This can be solved by installing a valid certificate on the server and workstations, then configuring TS to require 
mandatory authentication.

see Microsoft KB895433 for details.

"Don't leave port 3389 open on the Internet at all, the port is much
too vulnerable."

Explain.  What unpatched vulnerabilities for RDP exist in Server 2008?

Why is it more secure to provide your credentials to a third party and
to install a third party client on your machine?
