Re: Blocking Video/Audio Streaming

You absolutely can do this by integrating your PIX with a product like Websense.  (Guess who I work for).  PIXs 
natively support integration with Websense.  
   
  I will keep the commercial to a minimum but yes, Websense is a web security product and can filter/block Video and 
Audio streaming on a signature and port level.  So protocols trying to hide under say port 80 are still going to be 
detected and stopped.  Feel free to call me off list and I can go through our solution quickly for you.  I promise that 
I will NOT give up your name to a sale rep unless you want me to.

Subject: [fw-wiz] Blocking Video/Audio Streaming

Many of the streaming video/audios uses http port 80 as transport, It is
possible to 
block this type of traffic on Cisco PIX/IOS FW? a sample config will
really help me.

The HTTP fixup doesn't allow you to deny a/v streams or files over HTTP on
its own. You may be able to add an additional system (like a content filter
or and IDS) that can leverage the PIX to block the connection once it is
properly identified. Part of the problem is that you have a pretty big set
of detection factors for this stuff inside of the HTTP headers. Maybe MIME
type for some things, URL regex for others, and User-Agent for the rest.
PIX can't do that on its own.
