Re: ISA Server for Microsoft Exchange

["Di Fabio, Andrea" <adifabio () NSU EDU>]

We run MS Exchange without and use OWA as front end for webmail and we do not
run ISA.  WE only open port 80/443 on the firewall (CISCO ASA) and enable RPC
over HTTP.  I am not sure why you would need MS ISA.  Are you planning on
exposing the exchange servers to the internet directly, and if so, why?

Subject: [SECURITY] ISA Server for Microsoft Exchange
 
I am told that we need an ISA Server for Microsoft Exchange. I am asking for
the Reader's Digest condensed "english" explanation, but I am having a hard
time getting it.  :)  Can anyone here offer an explanation that will help me
to create a business case for this - for a non-technical audience? There is
a lot of info on the web, but nothing pops out as useful. I need a
translation from techno-speak to executive business need.

Thanks!
