Hi Guys
Can someome let me know whether there are websites available that allow you to view You Tube & Face Book content etc such that if it would not be detected and blocked by a URL filter?
Essenitially are there itermediate sites that could be used to achieve this and if so, how do i block it?
Would anonimizers provide this functionality?
Please note that I am not asking how to circumvent security but rather if it is possible and how to prevent users from doing it.
Regards
big

This solution is only available to members.

What kind of network appliances do you have at your disposal? I think you would need to do some deep packet inspection to see what is coming back. If the user is using https protocol, that should raise an easy check to see if the site is a proxy or actual site.
We achieved this by white listing the Internet sites people need access to.
We have a quick process for adding new sites based on brief business justification. We don't usually have any problem adding new sites or ports based on need.

As previous responses have said, one option is white-listing. We use Microsoft ISA proxy and MS reputation services, which blocks sites based on a threat rating and classification. In our experience, it has worked well to block proxy, social networking and chat sites.
