Modifying security for a WebSphere MQ link

Securing access between a service integration bus and a WebSphere® MQ Queue Manager.

About this task

When you create a new WebSphere MQ link, you can use the foreign bus connection wizard to enable security:
  • If the WebSphere MQ queue manager requires a secure connection, you can set the WebSphere MQ receiver channel to accept only connections that have secure sockets layer (SSL) based encryption.
  • If the local bus is secure, you can set the service integration bus inbound user ID to replace the user ID in messages from the WebSphere MQ queue manager, so that these messages are authorized to access their destinations.
    Inbound user ID
    If an inbound user ID is set, then all incoming messages will appear to have originated from that user ID. If the bus is security enabled then messages will appear authenticated as this user ID and have access to any resources that the user ID has access to.
    If an inbound user ID is not set, then messages will have the same user ID as in the WebSphere MQ message descriptor (MQMD) header of the WebSphere MQ message. These users will not be authenticated and therefore only have access to resources that require no authentication.
    Outbound user ID
    If an outbound user ID is set, then all outgoing messages will appear to have originated from that user ID (using the userid field of the MQMD)
    If an outbound user ID is not set, then messages will have the same user ID as in the original service integration bus message.

Use this task to secure the local and foreign bus that are part of a WebSphere MQ links configuration, and to secure an existing WebSphere MQ link that was not secured when it was first created.

For more general information about service integration bus security, see Securing service integration.

Procedure

  1. Enable security on the service integration bus and the foreign bus representing the WebSphere MQ network. See Securing buses.
  2. Secure the link between the buses - see Securing connections to a WebSphere MQ network.
  3. Grant access to the local bus for users who will be sending messages to the foreign bus - see Securing buses.
  4. Grant access to the foreign bus for users who will be sending messages to it - see Administering foreign bus roles.
  5. Optional: Give users access to foreign or alias destinations that will forward messages to a foreign bus - see Administering destination roles.
