+**Secure Boot** is a security standard that ensures a device boots only using software trusted by the original equipment manufacturer (OEM). It prevents malicious code, like [Malware](/wiki/malware), from loading during startup by validating the digital signatures of [Firmware](/wiki/firmware) and operating system components. If an unauthorized signature is detected, the system may refuse to boot, safeguarding the machine's integrity from its earliest moments.
