Extension settings for blocking online video

This issue has been solved. See solution.


I've been trying to block all streaming videos and to do that I've edited a black list entry by adding flv, rm and ram extensions then added this blacklist to the policy I'd created earlier. however it doesn't work. Could you please lead me what I must do? screen shots are below.

Hi Aydin,

Application Control (that must be enabled) includes the category "Streaming Media". You can configure a policy to block those. Did you already try that ?

yes, tried that, "streaming media" blocked already.

I've looked into this a few times, but this can be pretty tricky.  The big problem that you'll normally run into is that once you start to try blocking extensions like things like flv and asf, the problem is that flash video is used so widely now just in everyday websites that blocking this type of activity would lead to major browsing issues.

My recommendation would be to block access to the sites end users are going to to watch these online videos...

hi kevin,

I've already done what you suggested. the problem is, as you know, literally, there are thousands of video and proxy sites on the net. so, I guess it's OK to block the extensions. although it differs from company to company it's acceptable for us.

by the way, the policy I've created is working now. I suppose I was a bit hasty.
