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 IOA Facility Matrix table is defined as stated below, this is not a finding.
FAC(USERxx=NAME=IOA,PGM=IOA,ID=nn,ACTIVE,SHRPRF,ASUBM)
FAC(IOA=NOABEND,MULTIUSER,NOXDEF,SIGN(S),RES,LUMSG)
FAC(IOA=STMSG,WARNPW,NORNDPW,NOAUDIT,NOTSOC,MODE=FAIL)
FAC(IOA=LOG(SMF,INIT,MSG,SEC9),UIDACID=8,LOCKTIME=000)
Fix Text (F-26276r1146022_fix)
The BMC IOA systems programmer and the ISSO will ensure that the TOP SECRET Facility Matrix Table is proper defined using the following example:
IOA:
FACILITY(USERxx=NAME=IOA,PGM=IOA,ID=nn,ACTIVE,SHRPRF)
FACILITY(IOA=ASUBM,NOABEND,MULTIUSER,NOXDEF)
FACILITY(IOA=LUMSG,STMSG,SIGN(S),NORNDPW)
FACILITY(IOA=NOAUDIT,RES,WARNPW,NOTSOC)
FACILITY(IOA=MODE=FAIL,LOG(SMF,INIT,MSG,SEC9))
FACILITY(IOA=UIDACID=8,LOCKTIME=000)
