Allow usb devices by serial number? Lock out admin unless key is plugged in?


Recommended Posts

I thought of a cool random project. I wanted to disable root unless a specific usb device or multiple devices are plugged in. Better still a device with a specific serial number and some files containing passwords or keys. I had read that there are some udevs files you can edit and edit usb.c parameters. Is there a preferred way to go about this? Or maybe a .conf file that can be edited to make this happen?

Basically I want to lock out all devices except usb keys with certain serial numbers then block root access or any login unless the usb key is plugged in.

Is there an easy way to go about this? Is this easy to bipass?
