Encryption at Rest - DynamoDB Data Encryption

Heading

DynamoDB is a NoSQL database service provided by AWS. Encryption at rest is an important aspect of database security. DynamoDB provides built-in encryption at rest feature for data stored in tables.

Syntax

DynamoDB provides encryption at rest using their AWS KMS (Key Management Service). Encryption is enabled by default for all DynamoDB tables when using AWS KMS.

Example

Here is an example of how to enable encryption at rest for a DynamoDB table using AWS Management Console:

1. Open AWS Management Console and navigate to the DynamoDB service.
2. Select the table you want to enable encryption for.
3. Click on the Manage encryption button in the Overview tab.
4. Choose AWS owned CMK for the key management option.
5. Click on the Apply button to enable encryption.

Output

Once encryption is enabled, all data stored in the DynamoDB table is encrypted at rest.

Explanation

DynamoDB data encryption provides an additional layer of security to protect sensitive data stored in the tables. The encryption keys are managed by AWS KMS, ensuring high-level security.

Use

Encryption at rest should be enabled for all DynamoDB tables that store sensitive data, such as personally identifiable information (PII), financial data, or business-related information.

Important Points

• Encryption at rest is enabled by default for all DynamoDB tables when using AWS KMS.
• DynamoDB encryption uses AWS KMS for key management.
• All data stored in the DynamoDB table is automatically encrypted once encryption is enabled.

Summary

DynamoDB data encryption provides an effective mechanism for protecting data at rest. Encryption is enabled by default for all tables and can be managed using AWS KMS. DynamoDB encryption should be used for sensitive data stored in the tables.
