Security in AWS Snowball
Following, you can find information on security considerations for working with AWS Snowball. Security is a significant concern when transporting information of any level of classification, and Snowball has been designed with this concern in mind.
Server-Side Encryption in Snowball
AWS Snowball supports server-side encryption with Amazon S3–managed encryption keys (SSE-S3). Server-side encryption is about protecting data at rest, and SSE-S3 has strong, multifactor encryption to protect your data at rest in Amazon S3. For more information on SSE-S3, see Protecting Data Using Server-Side Encryption with Amazon S3-Managed Encryption Keys (SSE-S3) in the Amazon Simple Storage Service Developer Guide.
Currently, Snowball doesn't support server-side encryption with AWS KMS–managed keys (SSE-KMS) or server-side encryption with customer-provided keys (SSE-C).
