Security for IBM MQ Publish/Subscribe

There are additional security considerations if we are using IBM MQ Publish/Subscribe.

In a publish/subscribe system, there are two types of application: publisher and subscriber. Publishers supply information in the form of IBM MQ messages. When a publisher publishes a message, it specifies a topic, which identifies the subject of the information inside the message.

Subscribers are the consumers of the information that is published. A subscriber specifies the topics it is interested in by subscribing to them.

The queue manager is an application supplied with IBM MQ Publish/Subscribe. It receives published messages from publishers and subscription requests from subscribers, and routes the published messages to the subscribers. A subscriber is sent messages only on those topics to which it has subscribed.
