Fix Recommendation

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.

Each WebSphere MQ started task is associated with a unique ACID.

Each WebSphere MQ started task is defined to the STC record with a unique ACID.

Each ssidMSTR STC ACID has a corresponding WebSphere MQ MASTFAC as defined in the z/OS.

For example, a Started Task Table entry exists for each queue manager started task procedure xxxxMSTR and distributed queuing started task procedure xxxxCHIN. A corresponding userid for each started task exists. Queue manager and channel initiator started tasks will not be defined with the BYPASS attribute.

WebSphere MQ queue manager facilities are defined using the control options as specified below:

Define each queue manager xxxxMSTR to the TOP SECRET Facility Matrix Table using the following sample commands:

FACILITY(USERxx=NAME=xxxxMSTR)
FACILITY(xxxxMSTR=MODE=FAIL,PGM=CSQ,ID=xx)
FACILITY(xxxxMSTR=ACTIVE,SHRPRF,ASUBM,NOABEND)
FACILITY(xxxxMSTR=MULTUSER,XDEF,LUMSG,STMSG,SIGN(S))
FACILITY(xxxxMSTR=INSTDATA,NORNDPW,AUTHINIT)
FACILITY(xxxxMSTR=NOPROMPT,NOAUDIT,RES,WARNPW)
FACILITY(xxxxMSTR=NOTSOC,LCFTRANS,IJU,MSGLC,NOTRACE)
FACILITY(xxxxMSTR=NOEODINIT,NODORMPW,NONPWR)
(INIT,SMF,MSG,SEC9))
FACILITY(xxxxMSTR=DOWN=GLOBAL,LOCKTIME=00,DEFACID=(*NONE*))

Check Contents

Refer to the following reports produced by the TSS Data Collection:

- TSSCMDS.RPT(#STC).
- TSSCMDS.RPT(@ACIDS).
- TSSCMDS.RPT(FACLIST) - Preferred report containing all control option values in effect including default values.
- TSSCMDS.RPT(TSSPRMFL) - Alternate report containing only control option values explicitly coded at TSS startup.

Note: The FACLIST report must be created by security personnel. The TSSPRMFL report can be used if security personnel have not executed the required steps documented in the TSS Data Collection.

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.

Review WebSphere MQ started tasks and ensure the following items are in effect, this is not a finding.

For ssidMSTR
FACILITY(STC, BATCH)
PASSWORD(xxxxxxxx,0)
SOURCE(INTRDR)
NOSUSPEND
MASTFAC(ssidMSTR)

For ssidCHIN
FACILITY(STC, BATCH)
PASSWORD(xxxxxxxx,0)
SOURCE(INTRDR)
NOSUSPEND

WebSphere MQ queue manager facilities is defined to the Facility Matrix Table using the following sample commands:

FAC(USERxx=NAME=ssidMSTR,MODE=FAIL,PGM=CSQ,ID=xx,ACTIVE)
FAC(ssidMSTR=SHRPRF,ASUBM,NOABEND,MULTUSER,XDEF,LUMSG)
FAC(ssidMSTR=STMSG,SIGN(S),INSTDATA,NORNDPW,AUTHINIT)
FAC(ssidMSTR=NOPROMPT,NOAUDIT,RES,WARNPW,NOTSOC)
FAC(ssidMSTR=LCFTRANS,IJU,MSGLC,NOTRACE,NOEODINIT)
FAC(ssidMSTR=NODORMPW,NONPWR)
FAC(ssidMSTR=LOG(INIT,SMF,MSG,SEC9))
FAC(ssidMSTR=DOWN=GLOBAL,LOCKTIME=00,DEFACID=(*NONE*))

Repeat these steps for each queue manager ssid.
