  Another, more robust mechanism is the "trusted path". There is a
physical signal (usually a break) that the security kernel always
honors, placing the user in touch with known, trusted software to
start a logon sequence.
  A dedicated wire is even better, if you're on a workstation: you
press the magic button and the computer says "enter password to
login"
