Options
Descriptions
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.
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.
Audit Mode
In
Audit mode
, PK is not present. The BIOS does not authenticate
programmatic updates 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 starts the images
whether they pass or fail verification.
Audit Mode
is useful for programmatic determination of a working set of
policy objects.
Authorize Device Firmware
Specifies the status of the device firmware.
Secure Boot Policy Summary
Specifies the list of certificates and hashes that secure boot uses to authenticate images.
