Protecting data using encryption - Amazon Simple Storage Service

Protecting data using encryption

Data protection refers to protecting data while in-transit (as it travels to and from Amazon S3) and at rest (while it is stored on disks in Amazon S3 data centers). You can protect data in transit using Secure Socket Layer/Transport Layer Security (SSL/TLS) or client-side encryption. You have the following options for protecting data at rest in Amazon S3:

To see which percentage of your storage bytes are encrypted, you can use Amazon S3 Storage Lens metrics. S3 Storage Lens is a cloud-storage analytics feature that you can use to gain organization-wide visibility into object-storage usage and activity. For more information, see Assessing your storage activity and usage with S3 Storage Lens. For a complete list of metrics, see S3 Storage Lens metrics glossary.
