Configuring UEFI Secure Boot for OVA-based virtual machines

Last Updated : Jun 10, 2026 |

About this task

Unified Extensible Firmware Interface (UEFI) is an interface between the operating system and the platform firmware that replaces the legacy BIOS interface. Secure Boot is an UEFI feature that secures the operating system boot-up process by preventing the loading of boot loaders and drivers that are not signed with a trusted digital signature.

By default, Avaya Aura® Web Gateway Release 10.2.x OVA-based deployments have UEFI and Secure Boot enabled. For security reasons, Avaya recommends that you use Secure Boot whenever possible.

For more information about managing Secure Boot settings on VMware virtual machines, see UEFI Secure Boot in the VMware product documentation.
