A system owner needs a solution that identifies unexpected modifications in low-level code at early startup. Which choice is BEST for this requirement?
A specialized chip that applies cryptographic checks before the operating system starts
A monitoring service that calculates checksums after system services have initialized
An offsite backup plan that stores entire system images in another location
A scanning tool that updates security logs once the system has started
A specialized chip that enforces verification before the system is fully up can detect tampering in low-level code. Monitoring services or scanning tools begin their checks after the operating system starts, which may be too late to prevent firmware-based intrusions. Offsite backups focus on data recovery, not early detection of altered system components.
