Description

Elastic Compute Cloud (EC2) supports account-level encryption for Elastic Block Store (EBS) service, which uses Key Management Service (KMS) keys. Disabled encryption requires you to build, secure and maintain your own key management infrastructure. You can encrypt volumes and snapshots manually only at creation time - it is impossible to encrypt an existing unencrypted volume or snapshot. While enabled by default, new EBS volumes and snapshot copies are encrypted at rest, which provides an additional layer of data protection.

  Recommended Mitigation

  It is recommended to enable account-level encryption by default for your EBS volumes and snapshots in your cloud account {CloudAccount}. Enabling EBS default encryption allows to enforce the encryption of every new volume and snapshot copies create in a specific region.
