Post: Tips from a Tech in a Large WAN in Ohio

Hello,
I am a tech in a large Wide Area Network in Ohio, where we
have 6 site buildings, and our own data phone system.

While we rely upon our own Ohio School ISP provider for
most of our filtering, we realize that our young adults are
SMARTER THAN THEIR GRADES REFLECT. Isn't that a sad
statement?

By running security policies and mandatory profiles in
Windows 2003 Server Enterprise, we are able to minimize the
level of internet 'hacking'.
User data is stored on the network server, where "My
Documents" is linked to a network share via .VBS script.
We also use a software called "Deep Freeze", which locks
the hard drives in a permanent state. Upon reboot,
anything on the C:\ drive is instantly returned to the
original state. To date, I don't know of any way to hack
this program.
Our latest problem has been kids getting local
administrative privileges by physically disconnecting the
network cable, after having logged in. This problem has
been fixed by disabling "Log Off" using security policies.
(it forces them to shut down or restart)

The next big hurdle, is the abuse of "proxy bypass"
websites, that allow students to browse an unblocked
website, that ports them via a window, to sites that would
normally be blocked by our ISP proxy filter.

Any hints on conquering this Proxy Bypass problem would be
most appreciated!!!
