Re: [FW-1] MSN and Yahoo messenger



You should not under any circumstance let these through IMHO. They present a real threat to your network.
There have been several IM spread virus outbreaks already and just today CERT issued a bulletin about
the Yahoo product. If people have to IM, either try and get a professional-grade product with encryption and logging
in place or have them use the web-based AIM product which does not, as far as I know, allow the remote launching of
apps and file downloads, etc.
I realize this doesn't answer your question, but it's IMHO very important to understand the risks involved and make sure
that management does as well so the decision to let it through does not come back to haunt you. My prediction FWIW
is that this is going to get worse before it gets better.
