Amazon Web Services SAP-C02 Dumps

Integrate ALB with OIDC IdP:

In the AWS Management Console, navigate to the Application Load Balancer (ALB) settings.

Configure the ALB to use the OpenID Connect (OIDC) IdP for authentication. This ensures that all requests routed through the ALB are authenticated using the IdP.

Set Up Authentication Rules:

Create a listener rule on the ALB that requires authentication. This rule will forward requests to the IdP for user authentication before allowing access to the backend services.

Restrict Unauthenticated Access:

Ensure the ALB only forwards requests to backend services if the user is authenticated. Unauthenticated requests should be blocked or redirected to the IdP for authentication.

Update CloudFront Configuration:

Modify the CloudFront distribution to forward authenticated requests to the ALB. Ensure that the ALB and API Gateway accept only requests coming through the CloudFront distribution to enforce consistent authentication and security.

By enforcing authentication at the ALB level, you ensure that all backend services are accessed only by authenticated users, enhancing the overall security of the web application

This option uses Amazon Elastic Container Service (Amazon ECS) with the Fargate launch type to deploy the application containers. Amazon ECS is a fully managed container orchestration service that allows running Docker containers on AWS at scale. Fargate is a serverless compute engine for containers that eliminates the need to provision or manage servers or clusters. With Fargate, the company only pays for the resources required to run its containers, which reduces costs and operational overhead. This option also uses Amazon Elastic File System (Amazon EFS) for shared storage. Amazon EFS is a fully managed file system that provides scalable, elastic, concurrent, and secure file storage for use with AWS cloud services. Amazon EFS supports NFS version 4 protocol, which is compatible with the application’s requirements. To use Amazon EFS with Fargate containers, the company needs to reference the EFS file system ID, container mount point, and EFS authorization IAM role in the ECS task definition.

Store Secret in AWS Secrets Manager:

Create a random string in AWS Secrets Manager to be used as a custom HTTP header value.

Set Up Automatic Rotation:

Implement a Lambda function to handle automatic rotation of the secret in AWS Secrets Manager, ensuring the header value remains secure.

Configure CloudFront Custom Header:

In the CloudFront distribution settings, configure an origin custom header with the name and value from AWS Secrets Manager. This header will be included in requests forwarded to the ALB.

Create AWS WAF Web ACL:

Create a Web ACL in AWS WAF with a string match rule to allow requests that include the custom header with the correct value.

Associate the Web ACL with the ALB to filter incoming traffic based on the custom header.

By using this method, you can ensure that only requests coming through CloudFront (which injects the custom header) can reach the ALB, enhancing the origin security
