Rotate Amazon RDS Database Credentials Automatically With AWS Secrets Manager

AWS Secrets Manager is a revolutionary service designed to streamline the process of rotating, handling, and retrieving database credentials. With its user-friendly configuration options, Secrets Manager enables effortless automatic rotation of secrets, thereby addressing crucial security requirements.

Notably, Secrets Manager provides seamless integration capabilities for popular databases like MySQL, PostgreSQL, and Amazon Aurora on Amazon RDS, empowering the rotation of credentials for these platforms. Additionally, Secrets Manager offers enhanced control over access to secrets by leveraging the robust AWS Identity and Access Management (IAM) policies. 

As a result, AWS Secrets Manager encompasses a plethora of essential features that optimize credential management and enhance overall security measures, such as:

1. Secure Storage: AWS Secrets Manager provides a secure and centralized repository for storing sensitive information such as API keys, database credentials, and other secrets. The secrets are encrypted at rest using AWS Key Management Service (KMS), ensuring data protection.
2. Secrets Rotation: Secrets Manager offers built-in rotation functionality, allowing you to rotate secrets automatically and securely on a predefined schedule. This helps in mitigating security risks associated with long-lived credentials.
3. Integration with AWS Services: Secrets Manager seamlessly integrates with various AWS services, such as Amazon RDS, Amazon Redshift, and Amazon DocumentDB. This integration lets you easily retrieve secrets directly from these services, eliminating the need for hardcoding credentials in your applications.
4. Fine-Grained Access Control: Secrets Manager provides granular access control through AWS Identity and Access Management (IAM) policies. You can define who can access and manage specific secrets, ensuring proper authorization and least privilege principles.
5. Auditing and Monitoring: Secrets Manager integrates with AWS CloudTrail to provide detailed audit logs of all secret-related activities. You can track who accessed or modified secrets, helping you meet compliance requirements and monitor for any unauthorized access attempts.
6. Programmatic Access: Secrets Manager offers a straightforward API and SDKs, allowing you to retrieve secrets from your applications programmatically. This enables secure and dynamic retrieval of secrets without exposing sensitive information in code or configuration files.
7. Versioning and Secret History: Secrets Manager maintains a history of secret versions, enabling you to retrieve previous versions if needed. This feature is valuable for auditing purposes and allows for easy recovery in case of accidental changes.
8. High Availability and Scalability: Secrets Manager is designed to be highly available and scalable, ensuring reliable access to secrets even under high demand or during periods of increased workload.

Steps to configure Secrets Manager:

Note: Launch an RDS Database before proceeding to the Secrets Manager configuration.

1. Go to the AWS Management Console (https://console.aws.amazon.com) and sign in with your AWS account credentials.
2. Navigate to the Secrets Manager service by typing “Secrets Manager” in the search bar or finding it under the “Security, Identity & Compliance” section.
3. Click the “Store a new secret” button to create a new secret.
4. Choose the type of secret you want to store. This can include database credentials, API keys, or other types of sensitive information.
5. Keep the Encryption Key as Default as Secrets Manager creates a default encryption key for the secret being created. 
6. The Database section lists all the supported RDS Database which are there in the AWS account. Select the RDS Database from the list which was created initially and click Next.
7. Provide the necessary details for the secret, such as the secret name, description, and the actual secret values. The values can be entered manually or imported from a file or another AWS service.
8. You can configure the rotation settings if you want to enable automatic rotation for the secret. This is useful for credentials that need to be regularly updated for security purposes.
9. Define the access control for the secret by specifying the AWS Identity and Access Management (IAM) policies. This determines which AWS users or roles can access and manage the secret.
10. Double-check your configurations and click on the “Store” or “Create” button to create the secret.
11. After creating the secret, you can test retrieving it programmatically using the AWS SDK or API. This ensures that the secret can be accessed securely by authorized applications.
12. From the Secrets Manager console, you can monitor and manage your secrets. You can view the secret details, track secret usage, enable rotation, and modify access control settings.
