Option Description
Secure Boot Policy When Secure Boot policy is set to Standard , the BIOS uses the system manufacturer key and certificates to
authenticate pre-boot images. When Secure Boot policy is set to Custom , the BIOS uses the user-defined key and
certificates. Secure Boot policy is set to Standard by default.
Secure Boot Mode Enables you to configure how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).
If the current mode is set to
Deployed Mode , the available options are User Mode and Deployed Mode . If the
current mode is set to User Mode , the available options are User Mode , Audit Mode , and Deployed Mode .
Options Description
User Mode
In User Mode , PK must be installed, and BIOS performs signature verification on
programmatic attempts to update policy objects.
BIOS allows unauthenticated programmatic transitions between modes.
Audit Mode
In Audit mode , PK is not present. BIOS does not authenticate programmatic updates to
the policy objects, and transitions between modes.
Audit Mode is useful for programmatically determining a working set of policy objects.
BIOS performs signature verification on pre-boot images and logs the results in the image
Execution Information Table, but approves the images whether they pass or fail
verification.
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.
