Description
WebSphere MQ resources allow for the control of administrator functions, connections, commands, queues, processes, and namelists. Some resources provide the ability to disable or bypass security checking. Failure to properly protect WebSphere MQ resources may result in unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of system services, applications, and customer data.

The IAO will ensure that all MQSeries/WebSphere MQ commands are restricted to authorized personnel. For all command resources (i.e., ssid.command) defined to TYPE(MQC) (i.e., MQCMDS resource class, ensure the following items are in effect: NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). 1) Access authorization restricts access to the appropriate personnel as designated in the table entitled Websphere MQ COMMAND SECURITY CONTROLS,in the zOS STIG Addendum. 2) All command access is logged as designated in the table entitled Websphere MQ COMMAND SECURITY CONTROLS, in the zOS STIG Addendum.
