A company is reviewing its 1AM policies.

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.
