In today’s connected world, Secure Boot plays a pivotal role in fortifying IoT devices. It ensures the integrity and trustworthiness of boot-time software by validating digital signatures, guarding against malicious attacks. This essential security measure is implemented in device firmware, such as BIOS or UEFI, confirming the legitimacy of boot loaded software components. Notably, Secure Boot reduces the susceptibility to rootkits and firmware-level threats, fostering a secure foundation for IoT systems.
