What BIOS/UEFI feature performs multiple verifications during start-up?

Secure Boot is a critical feature in modern BIOS/UEFI firmware that enhances security during the boot process. Its primary function is to ensure that only trusted and authenticated software is allowed to run during system startup. This feature performs multiple verifications of the bootloader and operating system components before they are executed. By checking digital signatures against a list of trusted keys stored in the firmware, Secure Boot helps prevent unauthorized access and protects against rootkits and malware that might attempt to load during the boot process.

In contrast, boot order simply determines the sequence of devices the system will check for bootable media, which does not contribute to security or verification. Flashing refers to the process of updating the BIOS/UEFI firmware, which does not inherently include verification aspects during start-up. The Hardware Root of Trust provides a foundation for security features by ensuring that hardware components are genuine and unaltered, but it does not specifically focus on the multiple startup verifications performed by Secure Boot.
