If you mean in relation to computers - a Local Area Network (LAN) with NO access to the internet is the safest network. Take, for example a UNIX network. Each terminal ONLY has a screen and keyboard, with NO disc drives.

It's also the only place anyone could copy anything off the network to floppy disk etc.
