Ensure FTP.DATA configuration statements enforce secure configuration

HighLevel 1Manual reviewibm-z

Description

The statements in the FTP.DATA configuration file specify the parameters and values that control the operation of the FTP Server components including the use of anonymous FTP. Several of the parameters must have specific settings to provide a secure configuration. Inappropriate values could result in undesirable operations and degraded security. This exposure may result in unauthorized access impacting data integrity or the availability of some system services.
