title: Securing access to REST API of Kafka Connect
body: <p>The REST API for Kafka Connect is not secured and authenticated.
  Since its not authenticated, the configuration for a connector or Tasks are easily accessible by anyone. Since these configurations may contain about how to access the Source System [in case of SourceConnector] and destination system [in case of SinkConnector], Is there a standard way to restrict access to these APIs?</p>
