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 CONTROL-O Facility Matrix table is defined as follows, this is a finding.
FAC(USERxx=NAME=CONTROLO,PGM=CTO,ID=nn,ACTIVE,SHRPRF)
FAC(CONTROLO=ASUBM,NOABEND,MULTIUSER,NOXDEF,SIGN(S))
FAC(CONTROLO=RES,LUMSG,STMSG,WARNPW,NORNDPW)
FAC(CONTROLO=NOAUDIT,NOTSOC,MODE=FAIL)
FAC(CONTROLO=LOG(SMF,INIT,MSG,SEC9),UIDACID=8,LOCKTIME=000)
Fix Text (F-26268r1145965_fix)
The BMC CONTROL-O systems programmer and the ISSO will ensure that the TOP SECRET Facility Matrix Table is proper defined using the following example:
CONTROLO:
FAC(USERxx=NAME=CONTROLO,PGM=CTO,ID=nn,ACTIVE,SHRPRF)
FAC(CONTROLO=ASUBM,NOABEND,MULTIUSER,NOXDEF)
FAC(CONTROLO=LUMSG,STMSG,SIGN(S),WARNPW,NORNDPW)
FAC(CONTROLO=NOAUDIT,RES,NOTSOC,MODE=FAIL)
FAC(CONTROLO=LOG(SMF,INIT,MSG,SEC9),UIDACID=8,LOCKTIME=000)
