Control: 2.2.1 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.
Encrypting data at rest reduces the likelihood that it is unintentionally exposed and can nullify the impact of disclosure if the encryption remains unbroken.
Remediation
From Console:
- Log in to AWS Management Console and open the Amazon EC2 console using https://console.aws.amazon.com/ec2/
- Under
Account attributes, clickEBS encryption. - Click
Manage. - Click the
Enablecheckbox. - Click
Update EBS encryption - Repeat for every region requiring the change.
Note: EBS volume encryption is configured per region.
From Command Line:
- Run
aws --region <region> ec2 enable-ebs-encryption-by-default.- Verify that
EbsEncryptionByDefault:trueis displayed. - Repeat every region requiring the change.
Note: EBS volume encryption is configured per region.
