The GSO UNIXOPTS record does not specify proper security settings for DFTGROUP and DFTUSER control options.

| a) Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ACFGSO) - Classification of System Automated Analysis Refer to the following report produced by the ACF2 Data Collection: - PDI(ZUSSA050) b) If system is classified or does not use the FTP socket application the UNIXOPTS record must specify DFTGROUP() and DFTUSER(), there is NO FINDING. c) If the system is a non classified system, running the FTP socket application and DFTGROUP and DFTUSER control options specify a logon id and GROUP profile, there is NO FINDING. d) If (b) or (c) above is untrue, this is a FINDING. |

| The IAO will ensure that UINIXOPTS record does not specify DFTGROUP and DFTUSER fields for classified systems and systems not using FTP. If system is classified or does not use the FTP socket application the UNIXOPTS record must specify DFTGROUP() and DFTUSER(). If the system is a non classified system, running the FTP socket application and DFTGROUP and DFTUSER control options specify a logon id and GROUP profile this is the proper security setting. Example: SET C(GSO) LIST UNIXOPTS CHOWNRES DFTGROUP(OMVSDGRP) DFTUSER(OMVSUSER) NODIRACC NODIRSRCH NOFSOBJ NOFSSEC NOGOSETGID NOHFSACL NOHFSSEC NOIPCOBJ NGROUPS(300) NOPROCACT NOPROCESS |
