MVS data sets provide the configuration, operational, and executable properties of WebSphere MQ. Some data sets are responsible for the security implementation of WebSphere MQ. Failure to properly protect these data sets may lead to unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of system services, applications, and customer data.
Refer to the following report produced by the ACP Data Collection: - SENSITVE.RPT(MQSRPT) Ensure ACP data sets rules for MQSeries/WebSphere MQ system data sets (e.g., SYS2.MQM.) restrict access as follows: NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). READ access to data sets referenced by the following DDnames is restricted to MQSeries/WebSphere MQ STCs, MQSeries/WebSphere MQ administrators, and system programming personnel. All access to these data sets is logged. DDname Procedure Description CSQINP1 ssidMSTR Input parameters CSQINP2 ssidMSTR Input parameters CSQXLIB ssidCHIN User exit library Note: WRITE/UPDATE and/or ALLOCATE/ALTER access to these data sets is restricted to MQSeries/WebSphere MQ administrators and systems programming personnel. WRITE/UPDATE and/or ALLOCATE/ALTER access to data sets referenced by the following DDnames is restricted to MQSeries/WebSphere MQ STCs, MQSeries/WebSphere MQ administrators, and systems programming personnel. All WRITE and ALLOCATE access to these data sets is logged. DDname Procedure Description CSQPxxxx ssidMSTR Page data sets BSDSx ssidMSTR Bootstrap data sets CSQOUTx ssidMSTR SYSOUT data sets CSQSNAP ssidMSTR DUMP data set (See note) ssidMSTR Log data sets Note: To determine the log data set names, review the JESMSGLG file of the ssidMSTR active task(s). Find CSQJ001I messages to obtain DSNs. ALLOCATE/ALTER access to archive data sets is restricted to MQSeries/WebSphere MQ STCs, MQSeries/WebSphere MQ administrator, and system programming personnel. All ALLOCATE/ALTER access to these data sets is logged. Note: To determine the archive data sets names, review the JESMSGLG file of the ssidMSTR active task(s). Find the CSQY122I message to obtain the ARCPRFX1 and ARCPRFX2 DSN HLQs. Except for the specific data set requirements just mentioned, WRITE/UPDATE and/or ALLOCATE/ALTER access to all other MQSeries/WebSphere MQ system data sets is restricted to the MQSeries/WebSphere MQ administrator and system programming personnel. If all the above are true, this is not a finding. If any item above is untrue, this is a finding.
The systems programmer will have the ISSO ensure that all update and alter access to MQSeries/WebSphere MQ product and system data sets are restricted to WebSphere MQ administrators, systems programmers, and MQSeries/WebSphere MQ started tasks. The installation requires that the following data sets be APF authorized. hlqual.SCSQAUTH hlqual.SCSQLINK hlqual.SCSQANLx hlqual.SCSQSNL hlqual.SCSQMVR1 hlqual.SCSQMVR2 Read access to data sets referenced by the CSQINP1, CSQINP2, and CSQXLIB DDs in the queue manager's procedure will be restricted to the queue manager userid, WebSphere MQ administrator, and systems programming personnel. Log all access to these data sets. Write and allocate access to data set profiles protecting all page sets, logs, bootstrap data sets (BSDS), and data sets referenced by the CSQOUTX and CSQSNAP DDs in the queue manager's procedure will be restricted to the queue manager userid, WebSphere MQ administrator, and systems programming personnel. Log all write and allocate access to these data sets. Allocate access to all archive data sets in the queue manager's procedure will be restricted to the queue manager userid, WebSphere MQ administrator, and systems programming personnel. Log all allocate access to these data sets.
