For security reasons in public spaces administrators choose to disable the USB interfaces.
Is there a possibility for having something like port knocking on disabled/sleeping USB interfaces?
Port knocking in this case would be a detection of a specific kind of device (basically from
lsusb information) and ideally some kind of special file inside of a USB pen drive.
Ideally, it would also require multiple USB pen drives with multiple password files.
Is this possible and was this ever done?
Would is be a secure method to unlock the USB interfaces for administrators and administrators only?
