Use ssl to secure the ftp
The FTP server provides enhanced security while sending and receiving files over a untrusted network. FTP server uses Secure Sockets Layer (SSL) to secure passwords and other sensitive data during an information exchange. The FTP server supports either SSL or TLS protected sessions, including client authentication and automatic sign-on (see SSL concepts for additional information about the TLS and SSL protocols).
Most SSL-enabled applications connect a client to separate TCP ports, one port for “unprotected” sessions and the other for secure sessions. However, secure FTP is a bit more flexible. A client can connect to a non-encrypted TCP port (usually TCP port 21) and then negotiate authentication and encryption options. A client can also choose a secure FTP port (usually TCP port 990), where connections are assumed to be SSL. The iSeries(TM) FTP server provides for both of these options.
Before you can configure the FTP server to use SSL, you must have installed the prerequisite programs and set up digital certificates on your iSeries.
