Discussion

Improperly defined security controls for the Product could result in the compromise of the network, operating system, and customer data.

Check

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 CL/SuperSession Facility Matrix table is defined as stated below, this is not a finding.

*KLS CL/SUPERSESSION FACILITY(USERxx=NAME=KLS) FACILITY(KLS=MODE=FAIL,ACTIVE,SHRPRF) FACILITY(KLS=PGM=KLV,NOASUBM,NOABEND,NOXDEF) FACILITY(KLS=ID=xx,MULTIUSER,RES,LUMSG,STMSG,WARNPW,SIGN(M)) FACILITY(KLS=NOINSTDATA,NORNDPW,AUTHINIT,NOPROMPT,NOAUDIT) FACILITY(KLS=NOTSOC,LOG(INIT,SMF,MSG,SEC9))

Fix

Define the CT/Engine started task name KLS as a Facility to TOP SECRET in the Facility Matrix Table using the following example:

*KLS CL/SUPERSESSION FACILITY(USERxx=NAME=KLS) FACILITY(KLS=MODE=FAIL,ACTIVE,SHRPRF) FACILITY(KLS=PGM=KLV,NOASUBM,NOABEND,NOXDEF) FACILITY(KLS=ID=xx,MULTIUSER,RES,LUMSG,STMSG,WARNPW,SIGN(M)) FACILITY(KLS=NOINSTDATA,NORNDPW,AUTHINIT,NOPROMPT,NOAUDIT) FACILITY(KLS=NOTSOC,LOG(INIT,SMF,MSG,SEC9))
