Check Text (C-255896r991589_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-59516r877348_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.
