Using Amazon Elastic Block Storage (EBS) to secure data

Amazon EBSAmazon Elastic Block Store (EBS) provides raw block-level storage that can be attached to Amazon EC2 instances. These block devices can then be used like any raw block device.

There are two ways that data can be protected when using EBS:

  1. Use the Amazon Identity Management Service to control access Elastic Block Store Volumes. This can be complimented with policy options that enforce policies such as multi-factor authentication, SSL links etc in addition to controlling or locking down originating IP addresses.
  1. Encrypted EBS volumes can be created.These encrypt data at rest.Note that once set an encrypted volume cannot later be unencrypted (the same as an unencrypted volume cannot be later encrypted).
