Ensure EBS volume encryption is enabled in all regions

HighLevel 1Manual reviewaws

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 of unintentional exposure and can nullify the impact of disclosure if the encryption remains unbroken.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

From Console: 1. Login to the AWS Management Console and open the Amazon EC2 console using https://console.aws.amazon.com/ec2/. 2. Under Account attributes, click Data Protection and Security. 3. Under EBS encryption, verify that Always encrypt new EBS volumes displays Enabled. 4. Repeat for each region in use. Note: EBS volume encryption is configured per region. From Command Line: 1. Run the following command: aws --region <region> ec2 get-ebs-encryption-by-default 2. Verify that "EbsEncryptionByDefault": true is displayed. 3. Repeat for each region in use. Note: EBS volume encryption is configured per region.

How it is fixed

Fix method: Guidance or infrastructure patch

From Console: 1. Login to the AWS Management Console and open the Amazon EC2 console using https://console.aws.amazon.com/ec2/. 2. Under Account attributes, click Data protection and security. 3. Under EBS encryption, Click Manage. 4. Check the Enable box to default encryption. 5. Click Update EBS encryption. 6. 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: 1. Run the following command: aws --region <region> ec2 enable-ebs-encryption-by-default 2. Verify that "EbsEncryptionByDefault": true is displayed. 3. Repeat for each region in which EBS volume encryption is not enabled by default. Note: EBS volume encryption is configured per region.
