Most of the users at my employer of laptops and have local admin rights, as a result they tend to 'play' alot. Some users have found programs that will find any open outbound port bypassing our proxy, url, router and firewall filtering. The program is 'guaranteed to bypass any network blocks'. I tested this application off business hours. I blocked all outbound ports expect smtp, i blocked hotmail by url and and IP. I then tried various things from a standard client and could not connect to hotmail. Went to a client with this application and had no problems. Repeated test with various other websites and filesharing applications.
I have since created a login script that scans the local system for non standard company applications with one is found the PC is shut down, the users account is locked and Domain Admins are notified to the new program.
