I want to have live mode on the host for Whonix KVM, so Using Debian 10.10. I’ve installed grub-live for that purpose, which worked all fine and I got the new entry in the bootloader. But when I run the livecheck.sh I get the following output:
Thanks for the answers and sorry for the late reply.
I found some drives which are RO-lockable. Also found SD Card to be a possible solution.
But I have just learned that the switch on SD Cards just sets one of the pins to a certain state which the card reading device can choose to ignore, like my usb card reader does.
Assuming a card reader which respects the lock: Is this possibly a security threat that an attacker could deactivate this safeguard somehow and place harmful data onto the drive?
