A business is using Amazon EMR for processing and analyzing their big data. They have a strict requirement to encrypt their data at rest and in transit. Which EMR security configuration best meets their needs?

Correct Answer: Encryption on EMRFS with SSE-S3, and enforcing SSL for all job communications

For end-to-end data encryption at rest and in transit, you can use encryption on EMRFS with Server-Side Encryption with S3-Managed Keys (SSE-S3) and enforce SSL for all job communications to secure data in transit. Other options do not provide complete encryption at rest and in transit.
