Question #: 21
Topic #: 9

A company is reviewing its 1AM policies. One policy written by the DevOps engineer has been (lagged as too permissive. The policy is used by an AWS Lambda function that issues a stop command to Amazon EC2 instances tagged with Environment: NonProduccion over the weekend. The current policy is:

What changes should the engineer make to achieve a policy ot least permission? (Select THREE.)

AOption A

BOption B

COption C

DOption D

Show Suggested Answer

Suggested Answer: A, B, D

The engineer should make the following changes to achieve a policy of least permission:

A:Add a condition to ensure that the principal making the request is an AWS Lambda function. This ensures that only Lambda functions can execute this policy.

B:Narrow down the resources by specifying the ARN of EC2 instances instead of allowing all resources. This ensures that the policy only affects EC2 instances.

D:Add a condition to ensure that this policy only applies to EC2 instances tagged with ''Environment: NonProduction''. This ensures that production environments are not affected by this policy.

Exactly, we need to limit the actions the Lambda function can perform.

Yes, that would restrict access and make it more secure.

I think adding conditions to the policy would definitely help.

Yes, limiting the action to only what is necessary is a best practice in security policies.

I also believe changing the Action from 'ec2:StopInstances' to 'ec2:StopInstances' would be a good move.

I think the engineer should remove the unnecessary resource star in the resource section.

Haha, imagine if the policy was even more permissive - like 'Stop all instances, even the production ones!' That would be a real disaster waiting to happen. But yeah, B, D, and F sound like a good way to go here.

Alright, let's do this! I'm feeling good about A, C, and E. Gotta keep those permissions locked down tight, you know?

Yeah, this is a tricky one. We need to find the right balance between security and functionality. I'm leaning towards B, D, and E - that should give us the least permissive policy while still allowing the necessary actions.

I agree, this policy is way too open. Restricting the actions to only the necessary ones makes a lot of sense. I'd also add option C to the mix - we don't want to accidentally stop any production instances.

I agree, the current policy is way too permissive. We need to really lock it down and only allow the bare minimum required permissions.

This is a tricky question, but I think the key is to minimize the permissions as much as possible. The current policy seems quite broad, so we'll need to tighten it up.
