Introduction

Welcome to another episode of the AWS tutorial! In today's tutorial, I will Show You how to effectively and securely store sensitive information using AWS Secrets Manager. With Secrets Manager, you can safely store and retrieve passwords, API keys, or any other sensitive information that you may not feel comfortable storing in your application code.

What is AWS Secrets Manager?

AWS Secrets Manager is a service provided by Amazon Web Services (AWS) that allows you to securely store and manage sensitive information. It acts as a vault for your secrets, ensuring that they are protected and only accessible to authorized applications or services.

Why is Secrets Manager important?

In the real world, every application needs to access databases or other resources that require sensitive information such as usernames and passwords. However, it is not safe to expose these credentials in your application code. This is where Secrets Manager comes in handy. It allows you to store these sensitive credentials securely in a vault and configure access permissions for selective applications.

Storing Secrets in AWS Secrets Manager

To store secrets in AWS Secrets Manager, follow these steps:

1. Creating a Secret

In the AWS Management Console, navigate to AWS Secrets Manager and click on "Create a new secret". Choose the type of secret you want to store (e.g., plain text for API keys).

2. Configuring Secret Type

Specify the key-value pairs for your secret. For example, you can store an API key with its corresponding value. You can add multiple key-value pairs depending on your requirements.

3. Adding Key-Value Pairs

Specify the path or secret name and provide a Meaningful description for your secret. Configure any additional settings, such as enabling auto-rotation for added security. Once done, click "Store" to save your secret.

Accessing Secrets with AWS Lambda

To access secrets stored in AWS Secrets Manager using AWS Lambda, follow these steps:

1. Creating IAM Policy

Before creating an IAM role, you need to create an IAM policy that defines the permissions required to access the secrets. In the policy, specify the Secrets Manager service and allow only the necessary Read access to the secrets (identify the specific secret ARNs).

2. Creating IAM Role

Next, create an IAM role for the Lambda function that will be used to access the secrets. Attach the previously created policy to the role to grant the necessary permissions.

3. Creating a Lambda Function

Create a new Lambda function in the AWS Management Console. Specify the function name, runtime (Python in this case), and the IAM role that was created in the previous step.

4. Writing Code to Access Secrets

In the Lambda function, import the necessary libraries (boto3, base64, and client error) and define the environment variable for the secret name. Use the boto3 library to retrieve the secrets from AWS Secrets Manager. Handle potential exceptions and decode the secrets if necessary. Customize the code to suit your specific requirements.

Testing the Functionality

Once the Lambda function is set up and the code is written, you can test the functionality by creating test events. Define the environment variable for the secret name and run the test. Confirm that the function successfully retrieves the secrets.

Conclusion

In this tutorial, you have learned how to effectively use AWS Secrets Manager to securely store and retrieve sensitive information. By following the steps outlined in this tutorial, you can ensure that your secrets are protected and only accessible to authorized applications. By leveraging AWS Secrets Manager and AWS Lambda, you can enhance the security and efficiency of your applications.
