Ensuring that your DocumentDB database instances have storage encryption enabled is a critical step in protecting your data at rest. DocumentDB uses AWS Key Management Service (KMS) to provide encryption for your data.
To ensure that storage encryption is enabled for your DocumentDB instances, you can follow these steps:
1. Enable Encryption: When creating a new DocumentDB instance, ensure that the "Enable encryption" option is selected. This will encrypt all data at rest, including backups and snapshots.
2. Verify Encryption: You can verify that encryption is enabled by checking the "Encryption at rest" attribute in the AWS Management Console or by using the AWS CLI or SDKs.
3. Use KMS: DocumentDB uses KMS to provide encryption for your data. Ensure that your KMS key policies and permissions are correctly configured to allow DocumentDB to use the KMS key.
4. Regularly review and update your encryption configurations: It is essential to regularly review and update your encryption configurations to ensure that your data remains secure over time.
By following these steps, you can help ensure that your DocumentDB instances have storage encryption enabled, and that your data is protected from potential security threats.
