Question

Quizplus · Accepted Answer

FTPS (FTP Security or FTP Secure) is a protocol that adds security to the traditional FTP protocol by using SSL/TLS encryption. SFTP (Secure FTP), on the other hand, is a completely different protocol that uses SSH (Secure Shell) to transfer files securely. Though both protocols provide secure file transfer, they have different implementations and work differently.
