Secure Boot

OS10 secure boot verifies the authenticity and integrity of the OS10 image. Secure boot protects a system from malicious code being loaded and executed during the boot process.

Using secure boot, you can validate the OS10 image during installation and on demand at any time.

Secure boot:
  • verifies the OS10 image with the digital signature before installation
  • prevents the OS10 software, including the kernel and system files, from being compromised during the boot operation
  • protects and validates the startup configuration file at startup

OS10 checks the validity of the OS10 image before you install or upgrade your system:

If you have already installed Release 10.5.1.0 or later, to enable secure boot, see Enable secure boot.
NOTE: You cannot directly go to ONIE from OS10, when secure boot is enabled. OS10 GRUB menu has options only for OS10 A and B. When you reload from OS10 to ONIE and when secure boot is enabled in OS10, go to BIOS and choose ONIE to boot.
