Description
Started tasks are used to execute WebSphere MQ queue manager services. Improperly defined WebSphere MQ started tasks may result in inappropriate access to application resources and the loss of accountability. This exposure could compromise the availability of some system services and application data.

ℹ️ Check
Refer to the following reports produced by the RACF Data Collection: - DSMON.RPT(RACSPT) - RACFCMDS.RPT(LISTUSER) Note: ssid is the queue manager name (a.k.a., subsystem identifier). Provide a list of all WebSphere MQ Subsystem Ids (Queue managers) and Release levels. ssidMSTR is the name of a queue manager STC. ssidCHIN is the name of a distributed queuing (a.k.a., channel initiator) STC. Review WebSphere MQ started tasks and ensure the following items are in effect, this is not a finding. ssidMSTR and ssidCHIN started tasks are associated with a unique userid. ssidMSTR and ssidCHIN started tasks userids are defined with the attribute of PROTECTED. ssidMSTR and ssidCHIN started tasks are defined to the STARTED resource class. Repeat these steps for each queue manager ssid.

✔️ Fix
Each queue manager started task procedure xxxxMSTR and distributed queuing started task procedure xxxxCHIN will have a matching profile defined to the STARTED resource class. Create a corresponding userid for each started task. The STC userids will be defined as PROTECTED userids. Queue manager and channel initiator started tasks will not be defined with the TRUSTED attribute. The following sample contains commands to properly define the required Started Procs: Note that this example uses "qmq1" as the value for ssid. AU qmq1mstr NAME('STC, MQSERIES') NOPASS DFLTGRP(STC) OWNER(STC) DATA('MQSERIES QUEUE MANAGER PROC') AU qmq1chin NAME('STC, MQSERIES') NOPASSDFLTGRP(STC) OWNER(STC) DATA('MQSERIES DISTRIBUTED QUEUING CHANNEL INIT PROC') RDEF STARTED qmq1mstr.
