Authorization

Authorization protects critical resources in a system by limiting access only to authorized users and their applications. It prevents the unauthorized use of a resource or the use of a resource in an unauthorized manner.

Authorization in IBM MQ

You can use authorization to limit what particular individuals or applications can do in your IBM® MQ environment.

Here are some examples of authorization in an IBM MQ environment:
  • Allowing only an authorized administrator to issue commands to manage IBM MQ resources.
  • Allowing an application to connect to a queue manager only if the user ID associated with the application is authorized to do so.
  • Allowing an application to open only those queues that are necessary for its function.
  • Allowing an application to subscribe only to those topics that are necessary for its function.
  • Allowing an application to perform only those operations on a queue that are necessary for its function. For example, an application might need only to browse messages on a particular queue, and not to put or get messages.
