Tectia Server for IBM z/OS offers an easy way to secure plaintext FTP connections with a feature called FTP-SFTP conversion.
When FTP-SFTP conversion is enabled on Tectia Server for IBM z/OS client tools, it automatically captures all FTP connections initiated on the client side and converts the data to use the Secure File Transfer Protocol (SFTP), instead. The transferred files are sent to a Secure Shell SFTP server in encrypted format.
Tectia Server for IBM z/OS should be installed on the same host with the FTP client, and a Secure Shell server must be installed on the same host with the original FTP server.
FTP-SFTP conversion can be configured to pick the user name, password, and destination host directly from the secured FTP client, and use them to open the secured communication channel. This removes the need for any additional configuration modifications or changes to the original FTP scripts or applications. In the Connection Broker configuration, this is done simply with one rule that can fit all FTP connections.
When the FTP-SFTP conversion is used, there is no need for a plaintext FTP server, as the connection is made to an SFTP server instead. This requires that any post-processing done by the FTP server must be redirected to be performed elsewhere.
