Though you speak of firewall DMZ configurations I've usually seen this
term (sandbox) used to refer to the rubber-walled "jail" environments
set up for software to run inside on a computer.

The computer may be a server in the example of a Web server process
running 'chroot()d' on a Unix machine -- and where even the CGI programs
spawned by http server run inside the 'defanged/neutered' chroot()
'sandbox' environment.

'sandbox' is also used to refer to the 'safe' mode the Java Virtual
Machine turns on when Java applets are run inside a Web browser
(ie. Netscape Navigator or MS IE) -- where local file I/O and most
network I/O is disabled.
