Amazon DOP-C02 Exam - Topic 6 Question 22 Discussion

A security team is concerned that a developer can unintentionally attach an Elastic IP address to an Amazon EC2 instance in production. No developer should be allowed to attach an Elastic IP address to an instance. The security team must be notified if any production server has an Elastic IP address at any timeHow can this task be automated'?
B) Attach an 1AM policy to the developers' 1AM group to deny associate-address permissions Create a custom AWS Config rule to check whether an Elastic IP address is associated with any instance tagged as production, and alert the security team

A security team is concerned that a developer can unintentionally attach an Elastic IP address to an Amazon EC2 instance in production. No developer should be allowed to attach an Elastic IP address to an instance. The security team must be notified if any production server has an Elastic IP address at any time

How can this task be automated'?

Show Suggested Answer Hide Answer
Suggested Answer: B

To prevent developers from unintentionally attaching an Elastic IP address to an Amazon EC2 instance in production, the best approach is to use IAM policies and AWS Config rules. By attaching an IAM policy that denies theassociate-addresspermission to the developers' IAM group, you ensure that developers cannot perform this action. Additionally, creating a custom AWS Config rule to check for Elastic IP addresses associated with instances tagged as production provides ongoing monitoring. If the rule detects an Elastic IP address, it can trigger an alert to notify the security team.This method is proactive and enforces the necessary permissions while also providing a mechanism for detection and notification.Reference: from Amazon DevOps sources

I’m leaning towards option B because it combines IAM policies with AWS Config, which seems like a solid way to ensure compliance.

I think using AWS Config rules sounds familiar, especially for monitoring resources. I practiced a question like this, but I can't recall the exact steps.

I remember studying IAM policies and how they can restrict permissions, but I'm not sure if just denying associate-address permissions is enough.

Hmm, I'm a bit confused on the best way to approach this. Should we be using CloudTrail logs, AWS Config rules, or a combination of both? I'm not sure which option would be the most effective and efficient way to monitor and remediate the issue. Maybe I should review the exam question again and see if I'm missing any key details.

Okay, I think I've got a good strategy for this. First, I'd create an IAM policy to deny the associate-address permission for all developer roles. Then, I'd set up an AWS Config rule to continuously check for any Elastic IPs attached to production instances and trigger a Lambda function to automatically detach the IP and notify the security team. Seems like a solid plan!

This seems like a straightforward security task. I'd start by looking at the IAM permissions for the developers and ensuring they don't have the ability to associate Elastic IPs. Then I'd set up an AWS Config rule to monitor for any Elastic IPs attached to production instances and alert the security team.

Hmm, this is a tricky one. I'm not sure if just denying the associate-address permission for developers is enough, as they could potentially find other ways to attach an Elastic IP. I think the best approach would be to use a combination of IAM policies, AWS Config rules, and Lambda functions to monitor and remediate any issues.

This seems like a pretty straightforward question. I'd go with option C - using a Token Vending Machine to get temporary credentials and serving the app from autoscaled EC2 instances. That way, the client can interact with DynamoDB without needing to manage credentials, and the infrastructure will scale as needed.
