Encryption for EBS Volumes Can Help You with Security and Compliance
On May 21, AWS launched encryption for EBS volumes, a frequently requested feature, which can help you meet stricter security and encryption compliance requirements. You can now create an encrypted EBS volume and attach it to an EC2 instance. Data on the volume, disk I/O, and snapshots created from the volume are all encrypted. The encryption occurs on the servers that host the EC2 instances, providing encryption for data as it moves between EC2 instances and EBS storage.
