It’s an ethernet wire that’s going to be exiting my house and running to a camera in a publicly accessible space. An attacker could disconnect the camera, connect a laptop and access my network. How could I protect against that (other than a physical lock)? I basically want to lock down that cable to the point where nothing works on it unless it’s the intended camera. If this was wireless, I’d just use MAC filtering, but I don’t see an equivalent for wired connections.
Omfg I remember when I was doing system controls some weird vendor tried to be fancy and say to only use their special wired ethernet cable. We discovered when we went to repair the machine that the device was just using a regular ethernet but they crossed 4 wires and the cable when connected corrected that which made changed it back to a standard ethernet. (think of the machinery that does things in factories that make stuff)
