Amazon DVA-C02 Exam - Topic 6 Question 29 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 29
Topic #: 6

An application that runs on AWS Lambda requires access to specific highly confidential objects in an Amazon S3 bucket. In accordance with the principle of least privilege a company grants access to the S3 bucket by using only temporary credentials.

How can a developer configure access to the S3 bucket in the MOST secure way?

AHardcode the credentials that are required to access the S3 objects in the application code. Use the credentials to access me required S3 objects.

BCreate a secret access key and access key ID with permission to access the S3 bucket. Store the key and key ID in AWS Secrets Manager. Configure the application to retrieve the Secrets Manager secret and use the credentials to access me S3 objects.

CCreate a Lambda function execution role Attach a policy to the rote that grants access to specific objects in the S3 bucket.

DCreate a secret access key and access key ID with permission to access the S3 bucket Store the key and key ID as environment variables m Lambda. Use the environment variables to access the required S3 objects.

Show Suggested Answer

Suggested Answer: A

Amazon Cognito User Pools:A managed user directory service, simplifying user registration and login.

Social Identity Providers:Cognito supports integration with external providers (e.g., Google, Facebook), reducing development effort.

IAM Roles for Authorization:Cognito-managed IAM roles grant fine-grained access to AWS resources (like Lambda functions).

Operational Overhead:Cognito minimizes the need to manage user identities and credentials independently.

Environment variables for keys? Seems like a bad idea to me.

Storing keys in Secrets Manager (Option B) is good too, but C is better.

I feel like storing keys as environment variables isn't secure enough, so option D seems risky. I think C is the safest bet here.

I practiced a similar question where using AWS Secrets Manager was mentioned, but I can't recall if it was better than using execution roles.

I'm not entirely sure, but I think hardcoding credentials is a big no-no, so option A should definitely be avoided.

I remember we discussed the principle of least privilege, and I think option C makes the most sense since it uses a Lambda execution role.

Okay, let me see if I've got this right. We want to grant the Lambda function access to the S3 bucket, but we need to do it in the most secure way possible. I'm leaning towards option C - creating a custom execution role with a policy that allows access to the specific S3 objects. Seems like the best way to follow the principle of least privilege.

I think option C is the way to go. Attaching a policy directly to the Lambda execution role is the most secure approach since it limits access to only the necessary S3 objects. Hardcoding credentials or storing them in environment variables just doesn't seem as robust.

Hmm, I'm a bit confused here. Option B with Secrets Manager seems like a good approach, but I'm not sure if that's the most secure way. I'll need to review the principles of least privilege and think through the tradeoffs of each option.

This seems like a straightforward security question. I'd go with option C - creating a Lambda function execution role with a policy that grants access to the specific S3 objects. That way, the credentials are not hardcoded or stored in environment variables, which could be a security risk.

From what I practiced, it seems like adding a global table region is the right move for multi-region setups, but I'm a little unsure about the details.

This seems pretty straightforward. I think the key is to configure the product to allow for the customization options at the order creation stage, like option D suggests.

Haha, hardcoding credentials in the app code? What is this, the 90s? Option C is the clear winner here. I'd rather not have my app get hacked because I stored sensitive info in plain sight.
