NOTE: READ access to all authenticated users is permitted. 2) WRITE and ALLOCATE access to the data set containing the FTP Data configuration file is logged. 3) WRITE and ALLOCATE access to the data set containing the FTP banner file is restricted to systems programming personnel. 4) READ access to the data set containing the FTP banner file is permitted to all authenticated users. NOTES: The MVS data sets mentioned above are not used in every configuration. Absence of a data set will not be considered a FINDING. The data set containing the FTP Data configuration file is determined by checking the SYSFTPD DD statement in the FTP started task JCL. The data set containing the FTP banner file is determined by checking the BANNER statement in the FTP Data configuration file. b) If all of the items in (b) are true, there is NO FINDING. c) If any item in (b) is untrue, this is a FINDING.
