What is Secure Boot?

Описание: What is secure boot?

Reposted from a series I'm uploading first on LinkedIn where I'm making these shortish videos on embedded security fundamentals. I’ve got some more videos in the queue, but I’m interested topics or questions you have about embedded security and I’ll see if I can make them into a video answer.

In this video I:

Present a definition of secure boot
Draw out the boot process of an ARM Cortex-A running Linux.
Discuss how each boot component has a part in secure boot.
Do some hand wringing over what exactly is secure boot.
Talk about how silicon vendors, OEMs, and standards bodies have different definitions.
Mention secure boot with regards to the TPM and x86 UEFI but then largely ignore those topics :-)
Trip over my own words but keep it in the video because one take, one life.
Ask some questions to myself, like is secure boot only for physical access concerns?
Ask y’all for feedback.
Awkwardly end the video as I accidently don’t hit the end-recording button.


I give training on these topics and more here: https://advancedsecurity.training/tra...
I'm posting these to linkedin first so if you want the latest videos, try there first:   / joshdatko
