Amazon CloudFront - Encryption at rest in Edge Locations
Does Amazon CloudFront do encryption at rest for its Edge Location nodes for the content it stores?
Scenario : CloudFront accessing its origins (S3, EC2, On-Prem, etc) and the contents is encrypted at REST at origin.
CloudFront Edge Location caches files being requested by the users and these files will stay there for hours, days (depending how it is set up) in the meantime what type of protection will CloudFront provide to these files that are available there at rest?

CloudFront uses SSDs which are encrypted for edge location points of presence (POPs), and encrypted EBS volumes for Regional Edge Caches (RECs).
