| 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. |
