Check Text ( C-59572r877343_chk )
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 (F-59515r877344_fix)
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.
