What should the security engineer do next to meet these requirements?

A company wants to monitor the deletion of AWS Key Management Service (AWS KMS) customer managed keys. A security engineer needs to create an alarm that will notify the company before a KMS key is deleted. The security engineer has configured the integration of AWS CloudTrail with Amazon CloudWatch.

What should the security engineer do next to meet these requirements?
A . Specify the deletion time of the key material during KMS key creation. Create a custom AWS Config rule to assess the key’s scheduled deletion. Configure the rule to trigger upon a configuration change. Send a message to an Amazon Simple Notification Service (Amazon SNS) topic if the key is scheduled for deletion.
B . Create an Amazon EventBridge rule to detect KMS API calls of DeleteAlias. Create an AWS Lambda function to send an Amazon Simple Notification Service (Amazon SNS) message to the company. Add the Lambda function as the target of the EventBridge rule.
C . Create an Amazon EventBridge rule to detect KMS API calls of DisableKey and ScheduleKeyDeletion. Create an AWS Lambda function to send an Amazon Simple Notification Service (Amazon SNS) message to the company. Add the Lambda function as the target of the EventBridge rule.
D . Create an Amazon Simple Notification Service (Amazon SNS) policy to detect KMS API calls of RevokeGrant and ScheduleKeyDeletion. Create an AWS Lambda function to generate the alarm and send the notification to the company. Add the Lambda function as the target of the SNS policy.

Answer: C

Explanation:

The AWS documentation states that you can create an Amazon EventBridge rule to detect KMS API calls of DisableKey and ScheduleKeyDeletion. You can then create an AWS Lambda function to send an Amazon Simple Notification Service (Amazon SNS) message to the company. You can add the Lambda function as the target of the EventBridge rule. This method will meet the requirements.
