What are secure FTP and Telnet?
Secure File Transfer Protocol (SFTP) is a secure method for transferring files from one computer to another through networks such as the Internet. This is to replace the insecure File Transfer Protocol (FTP) where data are transmitted in clear text and hence could be intercepted. With SFTP, login passwords and data are encrypted to provide a secure channel for data transfer.
Secure Shell (SSH) is a network protocol that provides a secure method for remote access. SSH was designed as a replacement for telnet and other insecure remote shell. Encryption is enforced to ensure a secure connection.
