UEFI Secure Boot is a technology that eliminates a major security void that may occur during a handoff between the UEFI firmware and operating system (DDOS). During UEFI Secure Boot, each component in the chain is validated and authorized against a specific certificate before it is allowed to load or run. It prevents execution of any unauthorized pre-boot code. UEFI firmware infrastructure performs EFI signature validation and binary loading within UEFI secure boot. When UEFI secure boot is enabled in the UEFI BIOS, the signature of EFI image loaded during boot is verified against keys preloaded in the BIOS, before loading the components.
The UEFI Boot options are enabled by default for all new DD models. By default, the boot setup password is the PSNT of the head unit. You must change this password during the first boot of the system. This password is used to protect the BIOS console from unauthorized modification.
