Administer topic roles
Service integration bus security uses role-based authorization. When messaging security is enabled, users and groups require authority to access a topic in a publish/subscribe topic hierarchy. By adding and removing users and groups in topic roles, you can control access to the topic.
You use the admin console to list, add and remove users and groups in the sender and receiver roles, and to define topic role inheritance. By default, a child topic inherits its topic roles from its parent topic. We can change the default roles for a particular topic by adding or removing topic roles at the topic level. We can also allow or block inheritance of topic roles at topic level.
We can add access roles for a topic before it exists.
Topics are created at runtime only, and exist only for as long as they are active.
For information about how to list, add, and remove users and groups in topic roles by using the admin console, refer to the following tasks.
- List users and groups in topic roles
- Add users and groups to topic roles
- Remove users and groups from topic roles
