In AWS, we enable encryption at the EBS volume to ensure data security. It's a simple encryption solution that works without the need to build, create, and maintain your key management infrastructure.
Once we enable encryption on the EBS volume, it encrypts the following:
- Data at rest from volume
- All data moving between the volume and the instance
- All snapshots created from the volume
- All volumes created from these snapshots
The encryption operation occurs at host level, which hosts the EC2 instances and ensures encryption of data in transit and data at rest between EC2 instances and the attached volume.
All the EBS volumes support data encryption. There may be performance jitters (which are very, very significant) in ...
