As this is a fairly frequently asked question, I am suprised that we still
have not gotten a good answer. I can tell you that I have successfully been
blocking P2P and Chat for a while now using a few combination layers of
security. I am working to develop a document that will hopefully outline
this in more detail. For now, I can tell you that I am using firewall rules
to block Yahoo, MSN and AIM/ICQ servers in combination with a customized
block list for Snort with FlexResp and NTop to monitor any additional chats
that crop up. Please let me know if a solution like this would be worth the

Best Regards,

Does anyone have an effective way of blocking chat/IM?
