AWS IoT Core policy variables

AWS IoT Core defines policy variables that can be used in AWS IoT Core policies in the Resource or Condition block. When a policy is evaluated, the policy variables are replaced by actual values. For example, if a device is connected to the AWS IoT Core message broker with a client ID of 100-234-3456, the iot:ClientId policy variable is replaced in the policy document by 100-234-3456. For more information about policy variables, see IAM Policy Variables and Multi-Value Conditions.
