In addition to UEFI secure boot, the new Data Domain models include the Kernel Secure Boot feature which extends the validation and authorization chain from the Linux boot loader to the Linux kernel and modules. This helps to provide a secure boot sequence such that each component of the boot process (including BIOS, firmware, boot loader, kernel, and all device drivers) is validated and authorized against a known certificate before it is allowed to run.
Other existing features (such as multi factor authentication, role-based access control, Retention lock governance and compliance, and encryption) are also supported in new models PowerProtect Data Domain DD9410 and DD9910.
