EBS Default Encryption Enabled Rule
This rule ensures EBS default encryption is enabled to secure data. Currently, 23 instances do not comply.
| Rule | EBS default encryption should be enabled |
| Framework | NIST 800-53 Revision 5 |
| Severity | ✔ Medium |
Rule Description:
Enabling EBS default encryption is a best practice recommended by NIST 800-53 Revision 5 for enhancing the security of your AWS resources. By enabling this feature, all new EBS volumes created within your AWS account will be automatically encrypted with AWS Key Management Service (KMS) keys, providing an additional layer of protection for your data at rest.
Troubleshooting Steps:
If EBS default encryption is not enabled or you encounter any issues with the encryption process, please follow the troubleshooting steps below:
- 1.
Verify IAM permissions: Ensure that the IAM user or role used to enable EBS default encryption has the necessary permissions to access and manage KMS keys and EBS volumes. Specifically, the user or role should have permissions to create and manage KMS keys, as well as create and modify EBS volumes.
- 2.
Check KMS key policies: Confirm that the KMS key policies allow the IAM user or role to use the KMS key for encrypting EBS volumes. Make sure that the "kms:Encrypt" permission is included in the key policy.
- 3.
Ensure supported regions: Note that not all AWS regions support EBS default encryption. Ensure that you are working in a region that supports this feature. Refer to the AWS documentation for a list of supported regions.
- 4.
Verify KMS key configuration: Check the KMS key used for EBS default encryption and ensure that it is properly configured and enabled. Make sure the key has appropriate key rotation settings, key administrators, and other relevant configurations.
Necessary Codes:
There are no specific codes required for this rule. Enabling EBS default encryption can be done through the AWS Management Console or using AWS Command Line Interface (CLI) commands.
Step-by-Step Guide:
To enable EBS default encryption for NIST 800-53 Revision 5 compliance, follow the step-by-step guide below:
- 1.
Step 1: Log in to the AWS Management Console.
- 2.
Step 2: Navigate to the AWS Encryption Keys section in the AWS Management Console.
- 3.
Step 3: Select the AWS KMS key that you want to use for EBS default encryption. Ensure that the selected KMS key complies with the NIST 800-53 Revision 5 guidelines.
- 4.
Step 4: Enable the EBS default encryption feature by selecting the KMS key and applying the necessary settings.
- 5.
Step 5: Validate the configuration by creating a new EBS volume. Confirm that the newly created EBS volume is automatically encrypted with the selected KMS key.
- 6.
Step 6: Repeat the above steps for each AWS region you are using within your AWS account.
By following these steps, you can enable EBS default encryption for NIST 800-53 Revision 5 compliance and ensure that all new EBS volumes created within your AWS account are automatically encrypted using the selected KMS key.
