This doesn&#x27;t surprise me, most of the computers and other equipment in the research facility I work at are directly hooked up with Ethernet. The university manages it&#x27;s own IP block but doesn&#x27;t have any oversight over what goes on, no firewall. Most of the security is in the router which connects to the same network students on campus use. I&#x27;ve heard horror stories like the 2nd floor printer which was hijacked and turned into a porn server, researchers locked out of compromised equipment (worth millions). I spent months hardening my system and setting up my own local network after my first Linux box was rooted days after hooking it up (probably hours).
