Table 27. System Security details(continued)
Option Description
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.
Below are the details of different boot modes available in the Secure 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
preboot images and logs the results in the image Execution
Information Table. The BIOS runs 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.
Secure Boot Policy Summary Specifies the list of certificates and hashes that secure boot uses to authenticate
images.
Secure Boot Custom Policy
