For more information about permissions, see Example cases for Amazon Simple Notification Service access control in the Amazon Simple Notification Service Developer Guide.

The following is an example of an IAM policy that you attach to the destination Amazon SNS topic. It restricts the topic to DB instances with names that match the specified prefix. To use this policy, specify the following values:
