Description
A CloudWatch metric filter and alarm should be established for customer managed KMS keys that have changed state to disabled or scheduled deletion. This helps to prevent accidental or unintentional modifications that may lead to data loss. If KMS keys are disabled or deleted then any data encrypted with them will no longer be available.
How to fix?
Create an aws_cloudwatch_log_metric_filter and aws_cloudwatch_metric_alarm with an appropriate pattern attribute set for an aws_cloudwatch_log_group and aws_cloudtrail set of resources.
Use one of the following pattern attribute sets:
$.eventSource=kms.amazonaws.com
$.eventName=DisableKey
$.eventName=ScheduleKeyDeletion
OR
$.eventSource=kms*
$.errorMessage=*ispendingdeletion
