So, in what scenario are we talking here?  Someone bypasses the ISA,
passes an attack to the front end server, where a worm hits and installs
a trojan where it sniffs traffic?  Because if we're talking web browser
infection via a downloaded application, then you've got other issues
like why people are using your mail servers for surfing the internet and
installing Penguin Bowling.

Are there any proof of concept papers or anything on this that I can
look at on this?

Hi Dan,

Handy reminder. I've been seeing a lot of people proferring the "SSL
off-loading" option by doing SSL to HTTP bridging, and it's a suicide
waiting to happen. Just reinforcing the importance of SSL to SSL
bridging :)

Are you speaking from recent experiences or is this just a handy
reminder?

One more thing: use SSL to SSL bridging, or the trojans running network
sniffers on your "secure" network will capture your credentails because
someone told you "SSL off-loading" was a good idea.

Hey folks,
 
Anybody here using forms-based auth on the ISA firewall and not using
SSL?
 
If you're using FBA or Basic auth without SSL, crater your network,
change your passwords, because you've been owned.
 
HTH,
