Security After Secure Boot

How do I secure the contents of the root filesystem after a secure boot?

 

I have an application built on Yocto 3.14.52 that's deployed on an SD card within the product. The root filesystem contains sensitive information, and I'm concerned that unlike with on-chip memory, an attacker can just pop out the SD card and access the contents, no matter how secure the boot process is.

 

Is there a recommended approach to this with Yocto?
