Not really.
A student could come in five minutes before closing time, exercise their
"academic freedom", and bring down the whole network before you even
pulled the Ghost disk out of the cabinet.
Or I could come in a few minutes after opening, install a keyboard
tracker, have the results sent to me, and be able to gain access to
every e-mail and bank account that anyone who sat at that machine during
the day accessed. And by the time even the brightest figure out what
happened, that machine would have been Ghosted a few dozen times,
leaving a dead trail.
Let's hear it for "academic freedom"!

Another problem, too, is that Win9x, which is what was used
in those days, could not be locked down so easily, either.
Only the computer science department ever took the step
of locking down their machines, but installing Window NT
workstation on all of them. It was a matter of money. They
caught so much hell for raising student fees 40 percent in
1992, that they did not raise them for years. The CSU
system just did not have the money for the software
needed to lock down the machines. That is why only
the computer science department got Windows NT
on workstations in those days. For the college, it
was a matter of holding down spending costs, while
raising student fees as little as possible. |

Unfortunately, so is most malware that takes any interest in web

It's nice to have a backup, but reinstalling once a month? Posh. You
have other issues if that is really necessary.
Norton Ghost restores Windows in only a few minutes.

So what? You still lose all subsequent changes and data, and are
still recreating a doomed, exploitable installation.

Thank you very much Norman for the useful links and information.
I'll try to get some easier access from this group of clueless
designers that assume that everybody has high speed cable and the
latest version of IE.

That depends on the cable modem. I had a friend come here for me, He

So I would say this does depend on how the cable modem is setup.
Perhaps some providers do allow the cable modems to be configured.

Unpatched and improperly firewalled. I would be willing to be money

Malware doesn't transmit large amounts of data at one time. Atleast,

What he has probably done is broken into the modem, and changed the
settings sent by the cable provider to allow a higher transfer rate.
This can be discovered by the cable provider by checking their logs.
They can then resend the correct config file, and watch to see if it
gets switched back again. At that point they know it's intentional, and
they often will cancel the account.
If you value your account, you're playing a dangerous game allowing your
friend to do this.
