Any host acting as a network appliance, such as a router or firewall,
should do that. Linux Router Project does that. You can have a
read-only boot medium such as cdrom, floppy, or hard drive. Hopefully,
it's physically read-only like a cd or a jumpered hard drive. To deal
with logs, I suggest the following:
* A ramdisk filesystem for logs, periodically emailed to you and then
deleted by logrotate
* a completely read-only filesystem with a network-based syslog host
* Or just no logs at all.
Also note that Yggdrasil's "Plug and Play Linux" distribution can
optionally boot completely off the cdrom.
