Abstract
Methods and systems for generating and using a BIOS security display include determining whether a change in a BIOS user setting is associated with security of an information handling system. When the BIOS user setting is associated with security, a security level for the BIOS may be calculated based on weighted security values for BIOS user settings. Security levels for boot phases may also be individually calculated. The security levels may be displayed in the BIOS to the user when the BIOS user setting is changed.
Claims18
A method comprising:
- responsive to detecting a change in a user setting of a basic input/output system (BIOS) from an old value to a new value for an information handling system, determining whether the user setting is associated with security of the information handling system;
- when the user setting is associated with security of the information handling system:
- determining a weighted security value for the user setting, wherein the weighted security value indicates an importance to security of the information handling system for the user setting;
- based at least in part on the weighted security value, calculating a security level for the BIOS;
- and
- updating a display element included in a BIOS user interface, the display element indicative of the security level for the BIOS.
An information handling system, comprising:
- a microprocessor subsystem having access to a non-volatile memory comprising a basic input/output system (BIOS), wherein the BIOS includes BIOS instructions executable by the processor subsystem to:
- detect a change in a user setting of the BIOS from an old value to a new value;
- determine whether the user setting is associated with security of the information handling system;
- when the user setting is associated with security of the information handling system:
- determine a weighted security value for the new value of the user setting, wherein the weighted security value indicates an importance to security of the information handling system for the new value;
- based at least in part on the weighted security value, calculate a security level for the BIOS;
- and
- update a display element included in a BIOS user interface, the display element indicative of the security level for the BIOS.
An article of manufacture comprising:
- a non-transitory computer-readable medium storing instructions, the instructions representing a basic input/output system (BIOS) for an information handling system, that, when executed by a processor of the information handling system, cause the processor to:
- detect a change in a user setting of the BIOS from an old value to a new value;
- determine whether the user setting is associated with security of the information handling system;
- when the user setting is associated with security of the information handling system:
- determine a weighted security value for the new value of the user setting, wherein the weighted security value indicates an importance to security of the information handling system of the new value;
- based at least in part on the weighted security value, calculate a security level for the BIOS;
- and
- update a display element included in a BIOS user interface, the display element indicative of the security level for the BIOS.
