About this talk

Verification of a portion of the media provides a serious design challenge, but it can be critical for the security of the media – the validation of files before use or execution can protect the volume from corruption. Google has pushed for fs-verity, but Linux file system adaptation to these new requirements is still incomplete. In this webinar you will learn: • How fs-verity and dm-verity compare, and the differences encountered by drivers and Linux file systems. • How fs-verity and dm-verity affect over-the-air updates.
