Connection security

Connection security checking is carried out either when an application program tries to connect to a queue manager by issuing an MQCONN or MQCONNX request, or when the channel initiator, or CICS or IMS adapter issues a connection request.

If you are using queue manager level security, we can turn connection security checking off for a particular queue manager, but if you do any user can connect to that queue manager.

For the CICS adapter, only the CICS address space user ID is used for the connection security check, not the individual CICS terminal user ID. For the IMS adapter, when the IMS control or dependent regions connect to WebSphere MQ, the IMS address space user ID is checked. For the channel initiator, the user ID used by the channel initiator address space is checked.

We can turn connection security checking on or off at either queue manager or queue-sharing group level.
