AWS Secrets Manager: Overview and Configuration Example

AWS Secrets Manager is a service that helps you protect access to your applications, services, and IT resources without the upfront investment and on-going maintenance costs of operating your own infrastructure. It enables you to rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle. Here's a detailed overview of AWS Secrets Manager along with a configuration example:

Features of AWS Secrets Manager:

1. Secure Secret Storage:

   • Provides secure storage for sensitive information, such as database credentials, API keys, and other secrets.
2. Automatic Rotation:
   • Supports automatic rotation of secrets, helping to enhance security by regularly updating sensitive information.
3. Access Control:
   • Integrates with AWS Identity and Access Management (IAM) for fine-grained access control to secrets.
4. Integration with RDS and Amazon DocumentDB:
   • Seamlessly integrates with Amazon RDS and Amazon DocumentDB for automatic credential rotation.
5. Audit Logging:
   • Generates detailed audit logs of secret usage and management activities.

Configuration Example:

Let's configure AWS Secrets Manager to create a new secret and demonstrate automatic rotation:

1. Login to AWS Console:

   • Navigate to the AWS Management Console.
2. Open Secrets Manager Console:
   • Click on the "Secrets Manager" service in the console.
3. Create a New Secret:
   • In the Secrets Manager console, click "Store a new secret."
   • Choose the type of secret you want to create (e.g., database credentials).
4. Configure Secret Details:
   • Provide details such as the database connection information, credentials, and other relevant information.
5. Define Rotation Settings:
   • Enable automatic rotation and configure rotation settings if applicable (automatic rotation is supported for certain types of secrets).
6. Set Access Control (Optional):
   • Define IAM roles and permissions to control access to the secret.
7. Review and Create:
   • Review the secret details and click "Store" or "Create secret" to save the secret.
8. Retrieve Secret Value:
   • In your application or AWS service, retrieve the secret value using the Secrets Manager SDK or AWS CLI.
9. Enable Automatic Rotation (Optional):
   • If applicable, enable automatic rotation for the secret to regularly update sensitive information.
10. Monitor Secret Usage:
    • Regularly monitor secret usage in the Secrets Manager console or use AWS CloudWatch for logging and monitoring.
11. Rotate Secrets Manually (Optional):
    • If automatic rotation is not applicable or enabled, manually rotate secrets when necessary.
12. Configure Rotation Lambda Function (Optional):
    • For custom secret types, configure a Lambda function for custom rotation logic.
13. Integrate with AWS Services (Optional):
    • Integrate the created secret with other AWS services, such as AWS Lambda, to securely retrieve sensitive information.
14. Update Secret (Optional):
    • Update secrets as needed, and Secrets Manager will propagate the changes to applications that use the secret.
15. Disable or Delete Secrets (Optional):
    • If a secret is no longer needed, disable or delete it through the Secrets Manager console.
