EBS Default Encryption for NIST 800-53 Revision 5
Description:
EBS (Elastic Block Store) default encryption is a feature provided by AWS that ensures all newly created EBS volumes are encrypted. This rule ensures compliance with the NIST 800-53 Revision 5 security control requirement for default encryption of EBS volumes.
Troubleshooting Steps:
- 1.Verify if EBS default encryption is not enabled.
- 2.Check IAM permissions to ensure the necessary access rights.
- 3.Verify if any custom scripts or applications are overriding the default EBS encryption settings.
Necessary Codes:
No specific code is required, as this is a configuration-based rule for EBS.
Remediation Steps:
To enable EBS default encryption for NIST 800-53 Revision 5, follow the steps below:
- 1.Open the AWS Management Console and go to the AWS EC2 service.
- 2.Click on "Encryption" in the left-hand navigation menu.
- 3.In the "EBS Encryption" tab, click on "Edit" next to "Default Encryption Setting".
- 4.Select the appropriate KMS (Key Management Service) key for EBS encryption or create a new one if necessary.
- 5.Click on "Save" to apply the changes.
Verification Steps:
To verify if EBS default encryption is enabled, follow the steps below:
- 1.Open the AWS Management Console and go to the AWS EC2 service.
- 2.Click on "Encryption" in the left-hand navigation menu.
- 3.In the "EBS Encryption" tab, check if the "Default Encryption Setting" is enabled.
- 4.Ensure that the KMS key selected for encryption is the desired one.
If the "Default Encryption Setting" is enabled and the correct KMS key is selected, EBS default encryption is successfully enabled for NIST 800-53 Revision 5.
Additional Information:
EBS default encryption provides an extra layer of security for data at rest. It ensures that all new EBS volumes created within an AWS account are automatically encrypted without the need for additional configuration. This reduces the risk of data exposure in case of a security breach or data leakage.
Enabling EBS default encryption helps organizations comply with security control requirements, such as NIST 800-53 Revision 5, which mandates the default encryption of EBS volumes. By following this rule, organizations enhance their overall security posture and protect sensitive data stored on EBS volumes.
