Re: SSH question

Well, with a small amount of compitency and ssh, you've lost the
ability to control any outbound data at the firewall.  It can all be
tunnelled over ssh.  And SSH can be tunneled via most companies' SSL
'proxies.'

Mind you, I don't see this as a problem, because thinking your
firewall controlled outbound data flow was always silly.  Its just
becoming sillier and sillier.

Note that if you allow inbound ssh, to a workstation, they can use
that to proxy just about anything, but if you allow inbound access to
any machine where someone who you don't trust has root, they can be a
proxy.
