The message service provides role-based security for message queues and message topics. The message service operations and the access categories required to use them are:
| Access category | Message service operations | 
|---|---|
| Consumer | Adding, removing, or acquiring access to listeners and message selectors, retrieving message queue and topic statistics | 
| Producer | Sending and publishing messages | 
| Security | Adding, configuring, and removing access roles | 
You need to assign permission for each access category separately.
