Brian's organization uses a process where a secure module boots systems, then monitors them as each boot stage proceeds. It validates each signed boot stage and reports on whether the boot process was correct or not when complete. What is the secure module used to verify these stages called?

A root of trust-based secure boot process validates each signed component as it starts and ensures that the trusted components are all loaded as part of the boot process. Changes to the components are reported as exceptions, meaning that the boot process cannot be properly verified or trusted. Secure initiation manager, boot hash, cryptographic boot manager were made up for this question.
