What is sFTP?
sFTP stands for secure file transfer protocol and it is a similar method of connection as regular FTP, only with added security. An FTP is created by someone who ‘hosts’ an FTP. This is known as an ‘FTP Server’ This is a file directory that they make available to external parties. Each party is given a username and password to connect to the server. The partner is known as an ‘FTP Client’. Once connected, the external can either put files onto the server or pull files off of the server, depending on what both parties intend to do.
For sFTP, there is an added layer of security beyond just a username and password. The Client party gives a key certificate to the Server party. When clients attempt to connect to an sFTP server, they must present with it their public key which is then validated by the server. This ensures authenticity of the connecting party and results in a more secure connection.
