Data encryption is achieved via Amazon's KMS by enforcing strong encryption standards as well as managing and protecting the keys themselves. Data is encrypted using the AES 256-bit encryption algorithm, which is considered as one of the best standards of data encryption. Amazon also ensures these standards are absolutely compliant with Health Insurance Portability and Accountability Act of 1996 (HIPAA), Payment Card Industry (PCI), and National Institute of Standards and Technology (NIST).
Encryption is performed on the following:
- Data at rest inside the volume
- All snapshots created from the volume
- All disk I/O
So, how is the data encrypted? AWS uses CMKs to encrypt EBS volumes. The CMKs are included by default with each region of AWS. Data can be either encrypted using the included CMKs, or a user can create a new CMK using the AWS...
