Protection against strangers walking up to your machine and using it is nice, and easy to do. Protection against viruses which install Trojan horses in your system would also be nice, but is very hard to do in systems where programs run with all the privileges of their users.

I wonder what are the operating systems where programs may be run with _less_ privileges than the user who starts them? Is VMS one of such systems? thanks - Igor.
