UEFI
Unified Extensible Firmware Interface
Modern firmware replacing BIOS, supporting Secure Boot.
UEFI is modern firmware that initializes hardware and loads the operating system, replacing the legacy BIOS with faster boot, larger disk support, and Secure Boot. Secure Boot verifies digital signatures on boot components to block rootkits and bootkits that load before the operating system. Threats include firmware implants that persist below the operating system layer. Recognizing UEFI Secure Boot as a defense against boot time malware is a recurring exam connection.
Looking UEFI up is step one. Getting tested on it is step two.
