Table 64. System Security details (continued)
Option Description
Below are the details of different boot modes available in the Se
cure Boot Mode
option.
User Mode In User Mode, PK must be installed, and BIOS performs
signature verification on programmatic attempts to update
policy objects. The BIOS allows unauthenticated programmatic
transitions between modes.
Audit mode In Audit Mode, PK is not present. BIOS does not authenticate
programmatic update to the policy objects and transitions
between modes. The BIOS performs a signature verification on
pre-boot images and logs the results in the image Execution
Information Table, but executes the images whether they pass
or fail verification. Audit Mode is useful for programmatic
determination of a working set of policy objects.
Deployed Mode Deployed Mode is the most secure mode. In Deployed Mode,
PK must be installed and the BIOS performs signature verification
on programmatic attempts to update policy objects. Deployed
Mode restricts the programmatic mode transitions.
