Description
Improperly defined security controls for BMC Mainview for z/OS could result in the compromise of the network, operating system, and customer data.

ℹ️ Check
Refer to the following report 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 Ensure the BMC Mainview for z/OS Facility Matrix table is defined as follows: 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)

✔️ Fix
The BMC Mainview for z/OS system programmer and the IAO 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)
