A DevOps Engineer Has Been Tasked with Ensuring That All

question 184

Multiple Choice

A DevOps engineer has been tasked with ensuring that all Amazon S3 buckets, except for those with the word "public" in the name, allow access only to authorized users utilizing S3 bucket policies. The security team wants to be notified when a bucket is created without the proper policy and for the policy to be automatically updated. Which solutions will meet these requirements?

• A) Create a custom AWS Config rule that will trigger an AWS Lambda function when an S3 bucket is created or updated. Use the Lambda function to look for S3 buckets that should be private, but that do not have a bucket policy that enforces privacy. When such a bucket is found, invoke a remediation action and use Amazon SNS to notify the security team.
• B) Create an Amazon EventBridge (Amazon CloudWatch Events) rule that triggers when an S3 bucket is created. Use an AWS Lambda function to determine whether the bucket should be private. If the bucket should be private, update the PublicAccessBlock configuration. Configure a second EventBridge (CloudWatch Events) rule to notify the security team using Amazon SNS when PutBucketPolicy is called.
• C) Create an Amazon S3 event notification that triggers when an S3 bucket is created that does not have the word "public" in the name. Define an AWS Lambda function as a target for this notification and use the function to apply a new default policy to the S3 bucket. Create an additional notification with the same filter and use Amazon SNS to send an email to the security team.
• D) Create an Amazon EventBridge (Amazon CloudWatch Events) rule that triggers when a new object is created in a bucket that does not have the word "public" in the name. Target and use an AWS Lambda function to update the PublicAccessBlock configuration. Create an additional notification with the same filter and use Amazon SNS to send an email to the security team.
