Fix Recommendation

The BMC Mainview for z/OS systems programmer and the ISSO will ensure that the TOP SECRET Facility Matrix Table is proper defined using the following example:

**** BBI3
*
FACILITY(USERxx=NAME=BBI3,PGM=BBM,ID=nn,ACTIVE,SHRPRF)
FACILITY(BBI3=ASUBM,NOABEND,MULTIUSER,NOXDEF)
FACILITY(BBI3=LUMSG,STMSG,SIGN(S),NORNDPW)
FACILITY(BBI3=NOAUDIT,RES,WARNPW,NOTSOC)
FACILITY(BBI3=MODE=FAIL,LOG(SMF,INIT,MSG,SEC9))
FACILITY(BBI3=UIDACID=8,LOCKTIME=000)

Check Contents

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

- 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.

If the BMC Mainview for z/OS Facility Matrix table is defined as stated below, this is not a finding.

BBI3:
FAC(USERxx=NAME=BBI3,PGM=BBM,ID=nn,ACTIVE,SHRPRF,ASUBM)
FAC(BBI3=NOABEND,MULTIUSER,NOXDEF,SIGN(S),RES,LUMSG)
FAC(BBI3=STMSG,WARNPW,NORNDPW,NOAUDIT,NOTSOC,MODE=FAIL)
FAC(BBI3=LOG(SMF,INIT,MSG,SEC9),UIDACID=8,LOCKTIME=000)
