what a safe idea from lammert about the stand-alone PC.
I agree with aspdaddy you should contract a vulnerability assesment firm to examine the programming of your site, so your webmaster applies those reports to strenghten its security.
There are many programs to monitor every activity of every PC remotely and report to you as the Manager, and there are also programs which prevent unauthorized access to CD/DVD trays or to USB unauthorized copying etc.
Goodwill teaching is sometimes not so effective as the monitoring measures hereby mentioned.
Keep all this in mind and contract an advanced security suite as Bullguard, which is highly custom-configurable.
