Title

IBM z/OS FTP.DATA configuration statements for the FTP Server must be specified in accordance with requirements. (Cat II impact)

Discussion

This requirement is intended to cover both traditional interactive logons to information systems and general accesses to information systems that occur in other types of architectural configurations (e.g., service-oriented architectures).

Check Content

Refer to the Data configuration file specified on the SYSFTPD DD statement in the FTP started task JCL. If the UMASK statement is coded with a value of "077", this is not a finding.

Fix Text

Configure the FTP configuration to include the UMASK statement with a value of "077". If the FTP Server requires a UMASK value less restrictive than "077", requirements should be justified and documented with the ISSO.
