Automatic Log off of Your Computer

In my business class that I am taking this semester, one of the chapters we are talking about is security in the workplace especially for computers. We talked about if a computer is left on and the person walks away from it, there are security risks of someone else taking private information from it. An auto log off programs is something cool to where once the computer goes to the screensaver, the adminstrative can put another timer on the computer to completely log off so that you have to log back in with passwords and such to get back on the computer. That is a cool thing for a business I think, at least it will help with keeping things private as much as possible.
