Ensure EMR clusters have encryption at rest enabled
EMR clusters should encrypt data at rest on EMRFS (S3), local disks, and EBS volumes to protect sensitive big data workloads.
Security Impact
Unencrypted data on EMR clusters exposes sensitive information if storage is compromised or instances are improperly decommissioned.
How to Remediate
Enable encryption at rest in security configuration. Use AWS KMS for key management. Apply security configuration to all new clusters.
