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.

a) Refer to the following reports produced by the RACF Data Collection: - DSMON.RPT(RACSPT) - RACFCMDS.RPT(LISTUSER) Provide a list of all WebSphere MQ Subsystem Ids (Queue managers) and Release levels. b) Review WebSphere MQ started tasks and ensure the following items are in effect: NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). ssidMSTR is the name of a queue manager STC. ssidCHIN is the name of a distributed queuing (a.k.a., channel initiator) STC. 1) Each ssidMSTR and ssidCHIN started task is associated with a unique userid. 2) All ssidMSTR and ssidCHIN started tasks are defined to the STARTED resource class. 3) All ssidMSTR and ssidCHIN started tasks userid are defined as a PROTECTED. c) If both of the items in (b) are true, there is NO FINDING. d) If either item in (b) is untrue, this is a FINDING.

a) Refer to the following reports produced by the RACF Data Collection:

- DSMON.RPT(RACSPT)
- RACFCMDS.RPT(LISTUSER)

Provide a list of all WebSphere MQ Subsystem Ids (Queue managers) and Release levels.

b) Review WebSphere MQ started tasks and ensure the following items are in effect:

NOTE: ssid is the queue manager name (a.k.a., subsystem identifier).
ssidMSTR is the name of a queue manager STC.
ssidCHIN is the name of a distributed queuing (a.k.a., channel initiator) STC.

1) Each ssidMSTR and ssidCHIN started task is associated with a unique userid.
2) All ssidMSTR and ssidCHIN started tasks are defined to the STARTED resource class.
3) All ssidMSTR and ssidCHIN started tasks userid are defined as a PROTECTED.

c) If both of the items in (b) are true, there is NO FINDING.

d) If either item in (b) is untrue, this is a FINDING.
