How does ERS FTP provide additional security?
SpringSource Enterprise FTP Server takes advantage of the filtering capabilities of Apache HTTP to enable FTP to be used with SSL. Both FTP and SSL are simply modules within the Apache framework, and the ability of Apache to cascade filters allows FTP to incorporate SSL. This enables IDs and passwords to be encrypted, as well as encryption of the transmitted data itself. And since SSL supports digital certificates, so, then, does FTP. Along the same lines, you can enforce client authorization on a per request basis.
