Hello Javier SBL has the necessary infrastructure to enable boot guard technology. However, enabling boot guard technology on a platform requires additional firmware components, tools and processes. These additional components and tools are to obtained by contacting your Intel representative. https://slimbootloader.github.io/security/boot-guard.html If there is interest, we may consider creating a stitching script that can help to create a boot guard enabled IFWI image with SBL.

Reding documentation, I have seen that currently boot guard is not supported. Does SBL support this feature? If answer is no, do you have any timeline to add support to this feature? Thanks, Javier P Please consider the environment before printing this e-mail.
