Use ASA to stop streaming music and video done via locally installed applications?
Posted on 2011-03-23
I have websense web filter setup in line with my Cisco ASA 5510's. I'm filtering perfectly all traffic that is done via ftp, http, and https in Internet Explorer. We are blocking all streaming media via Internet Explorer. So, if you go to youtube or pandora it is blocked via your web browser. Our problem is that some people are using Windows Media Player, Beer and hot wings, and other apps that aren't embedded into Internet Explorer to stream music. How can I stop this via the ASA?
Here is how my web filter is setup and running. What can I do with my ASA or websense to stop activity from successfully happening outside of Internet Explorer. As I see it websense only filters what the ASA sends it. ASA will only send certain types of traffic to Websense and I'm already doing that for all the options i see (http,https,ftp,java, url).
