Abstract
Methods and systems for platform configuration management may use a platform configuration register (PCR) stored on a trusted platform module (TPM) included with an information handling system. A basic input/output system (BIOS) may include instructions to generate a first PCR value based on BIOS settings while a user is operating the BIOS. When the first PCR value indicates a change from a previous PCR value stored in the PCR, an alert may be displayed to the user and sent to a network administrator. The BIOS may display an indication of a mapping of BIOS settings to the first PCR value.
Claims18
A method for platform configuration management, comprising:
- accessing a mapping of basic input/output system (BIOS) settings to a platform configuration register (PCR) for an information handling system including a trusted platform module (TPM);
- during operation of the BIOS by a user and based on the BIOS settings and the mapping, generating a first PCR value indicative of BIOS settings currently selected by the user, the first PCR value corresponding to the PCR;
- and
- when the first PCR value indicates a change from a previous PCR value stored in the PCR, displaying a first alert in a BIOS user interface, the first alert indicating that the BIOS settings have changed the first PCR value.
An information handling system, comprising:
- a processor subsystem having access to a basic input/output system (BIOS), wherein the BIOS includes BIOS instructions executable by the processor subsystem to:
- access a mapping of BIOS settings to a platform configuration register (PCR) for an information handling system including a trusted platform module (TPM);
- during operation of the BIOS by a user and based on the BIOS settings and the mapping, generating a first PCR value indicative of BIOS settings currently selected by the user, the first PCR value corresponding to the PCR;
- and
- when the first PCR value indicates a change from a previous PCR value stored in the PCR, displaying a first alert in a BIOS user interface, the first alert indicating that the BIOS settings have changed the first PCR value.
An article of manufacture comprising a non-transitory computer-readable medium storing instructions, the instructions representing a basic input/output system (BIOS), that, when executed by a processor of an information handling system, cause the processor to:
- access a mapping of BIOS settings to a platform configuration register (PCR) for an information handling system including a trusted platform module (TPM);
- during operation of the BIOS by a user and based on the BIOS settings and the mapping, generating a first PCR value indicative of BIOS settings currently selected by the user, the first PCR value corresponding to the PCR;
- and
- when the first PCR value indicates a change from a previous PCR value stored in the PCR, displaying a first alert in a BIOS user interface, the first alert indicating that the BIOS settings have changed the first PCR value.
