What are the key features of Intel Boot Guard?
The key features of Intel Boot Guard include:

Verified Boot: Intel Boot Guard ensures that only trusted firmware components are loaded during the boot process. It verifies the integrity of the BIOS/UEFI firmware, bootloader, and kernel using cryptographic measurements, preventing the system from booting if any of these components have been tampered with or modified.

Hardware-based Root of Trust: Boot Guard establishes a hardware-based root of trust by utilizing integrated Trusted Platform Module (TPM) or other secure hardware components to securely store cryptographic keys and measurements. This ensures that the verification process is resistant to attacks attempting to tamper with the boot process.

Enforcement of Firmware Policies: Boot Guard allows system administrators to configure policies to enforce specific firmware behavior, such as preventing unauthorized firmware updates or enforcing Secure Boot to only allow signed firmware components to run. These policies help mitigate the risk of unauthorized access or malware compromising the firmware.

End-to-End Security: By protecting the boot process from firmware-level attacks, Intel Boot Guard helps establish end-to-end security for the system, enhancing overall system integrity and protecting sensitive data from unauthorized access or manipulation.

Overall, Intel Boot Guard provides robust protection against firmware-level attacks, establishes a hardware-based root of trust, enforces firmware policies, and contributes to the overall security posture of Intel-based systems.
