Table 22. System Security details (continued) Option Description Custom, the BIOS uses the user-defined key and certificates. Secure Boot policy is set to Standard by default. Secure Boot Mode Configures 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. Table 23. Secure Boot Mode 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. 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. Secure Boot Policy Summary Secure Boot Custom Policy Settings Specifies the list of certificates and hashes that secure boot uses to authenticate images. Configures the Secure Boot Custom Policy. To enable this option, set the Secure Boot Policy to Custom option. Creating a system and setup password Prerequisites Ensure that the password jumper is enabled.
