Restricting Open Proxies

[shailesh.rangari () gmail com]

Hi List,

We are in the process of strengthening our Information Security Policy. As part of this initiative we want to restrict 
access to Open Proxies from the Corporate Network.

We are currently providing Internet Access through Symantec Web Security which also acts as a Proxy Server.

The access to Open Proxies that keep floating in the wild is bothering us because it might ultimately lead to 
Information Leakage. Has any one of you faced the same issue? What are the best practices for the same?

Any ideas or suggestions are most welcome.

Thanks
Shailesh.
