Control: 6.1.1 Ensure EBS volume encryption is enabled in all regions

Description

Elastic Compute Cloud (EC2) supports encryption at rest when using the Elastic Block Store (EBS) service. While disabled by default, forcing encryption at EBS volume creation is supported.

Remediation

From Console:

Login to the AWS Management Console and open the Amazon EC2 console using https://console.aws.amazon.com/ec2/.
Under Account attributes, click Data protection and security.
Under EBS encryption, Click Manage.
Check the Enable box to default encryption.
Click Update EBS encryption.
Repeat for each region in which EBS volume encryption is not enabled by default.

Note: EBS volume encryption is configured per region.

From Command Line:

Run the following command:

aws --region <region> ec2 enable-ebs-encryption-by-default

Verify that "EbsEncryptionByDefault": trueis displayed.
Repeat for each region in which EBS volume encryption is not enabled by default.

Note: EBS volume encryption is configured per region.

Default Value:

By default, EBS volume encryption is disabled. It must be manually enabled per region; otherwise, new EBS volumes are created unencrypted.
