**IAM roles used for resource permissions**

Because Firehose does not use resource policies, AWS uses IAM roles when setting up these logs to be sent to Firehose. AWS creates a service-linked role named **AWSServiceRoleForLogDelivery**. This service-linked role includes the following permissions.

    "Version":"2012-10-17",		 	 	 
    "Statement": [
        {
            "Action": [
                "firehose:PutRecord",
                "firehose:PutRecordBatch",
                "firehose:ListTagsForDeliveryStream"
            ],
            "Resource": "*",
            "Condition": {
                "StringEquals": {
                    "aws:ResourceTag/LogDeliveryEnabled": "true"
                }
            },
            "Effect": "Allow"
        }
    ]
}
```

------

This service-linked role grants permission for all Firehose delivery streams that have the `LogDeliveryEnabled` tag set to `true`. AWS gives this tag to the destination delivery stream when you set up the logging. 

This service-linked role also has a trust policy that allows the `delivery.logs.amazonaws.com` service principal to assume the needed service-linked role. That trust policy is as follows:
