Blocking Instant Messaging and Peer-to-Peer
Cisco has published a complete white paper on how to block IM and P2P applications using the Cisco IOS Firewall (the artist formerly known as CBAC). While there are many commands to be discussed for IOS Firewall, here's the core syntax needed:
appfw policy-name abuse-control
application http
port-misuse default action reset alarm
The complete white paper can be found here.

Dear Sir,
I have been reading your blog regularly and find it really interesting and informative. I
have a similar blog (http://www.cisco-tips.com) about Cisco networking technologies and I
would like to ask you if you are interested to exchange links on our Blogroll. I have
already added ciscoblog.com on my Blogroll and I would appreciate if you do the same as
well. I believe this will benefit both of us and most importantly our readers as well.
Have a happy new year.
Harris Andrea

This is a nice summary of how to do it, but I'm still not sold that it's necessary. Why aren't businesses working to enable secure use of the tools rather than just blindly blocking access?

Doing easy things is generally sjpposed in the minds placed under the last head, while at work, to count and report.
