Fix Recommendation

Define NETVIEW as a Facility to TOP SECRET in the Facility Matrix Table using the following example:

**** NETVIEW
*
FACILITY(USERxx=NAME=NETVIEW)
FACILITY(NETVIEW=MODE=FAIL)
FACILITY(NETVIEW=PGM=DSI)
FACILITY(NETVIEW=ACTIVE,SHRPRF,ASUBM,ABEND,MULTIUSER,NOXDEF)
FACILITY(NETVIEW=LUMSG,STMSG,SIGN(M),INSTDATA,NORNDPW,AUTHINIT)

FACILITY(NETVIEW=NOPROMPT,NOAUDIT,RES,WARNPW,NOTSOC,LCFTRANS,IJU)

FACILITY(NETVIEW=MSGLC,NOTRACE,NOEODINIT,NODORMPW,NONPWR)

FACILITY(NETVIEW=LOG(INIT,SMF,MSG,SEC9))

FACILITY(NETVIEW=DOWN=GLOBAL,LOCKTIME=00,DEFACID(*NONE*))

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 NETVIEW Facility Matrix table is defined as stated below, this is not a finding.

FACILITY(USERxx=NAME=NETVIEW)
FACILITY(NETVIEW=MODE=FAIL)
FACILITY(NETVIEW=PGM=DSI)
FACILITY(NETVIEW=ACTIVE,SHRPRF,ASUBM,ABEND,MULTIUSER,NOXDEF)
FACILITY(NETVIEW=LUMSG,STMSG,SIGN(M),INSTDATA,NORNDPW,AUTHINIT)
FACILITY(NETVIEW=NOPROMPT,NOAUDIT,RES,WARNPW,NOTSOC,LCFTRANS,IJU)
FACILITY(NETVIEW=MSGLC,NOTRACE,NOEODINIT,NODORMPW,NONPWR)
FACILITY(NETVIEW=LOG(INIT,SMF,MSG,SEC9))
FACILITY(NETVIEW=DOWN=GLOBAL,LOCKTIME=00,DEFACID(*NONE*))
