How to secure ftp in AIX

Hi,
the default ftp that comes with AIX5L is not secured as far as i know.
How to install and use the secured FTP in AIX?

Linux these days uses vsftpd daemon(very secured FTP daemon) is there VSFTPD for AIX?
if there is any where can i download it from?
thanks and regards

Secure FTP is part of most SSH packages, therefore this:
SSH on AIX
will help.
