SFTP, or Secure File Transfer Protocol, is a network protocol that provides secure file access, transfer, and management over a reliable data stream. Unlike traditional FTP, SFTP encrypts both commands and data, ensuring that sensitive information is protected during transmission. It operates over the Secure Shell (SSH) protocol, typically using port 22, and is widely used for secure file transfers across various industries.
Understanding the distinctions between these protocols is crucial for selecting the appropriate method for file transfers:
FTP (File Transfer Protocol): An older protocol that transfers files over a network without encryption, making it susceptible to interception and unauthorized access.
FTPS (FTP Secure): Enhances FTP by adding SSL/TLS encryption. While it secures the data, FTPS can be complex to configure due to its use of multiple ports and compatibility issues with firewalls.
SFTP (Secure File Transfer Protocol): A completely different protocol from FTP, SFTP uses SSH to provide a secure channel for file transfer. It encrypts both commands and data, operates over a single port, and is generally easier to configure and more secure than FTPS.
SFTP’s use of SSH for encryption and its single-port operation make it a preferred choice for secure and efficient file transfers.
SFTP operates over the SSH protocol to provide a secure connection between a client and a server. Here’s a simplified overview of its operation:
Connection Establishment: The client initiates a connection to the server over SSH.
Authentication: The server authenticates the client using methods such as passwords or SSH keys.
Secure Channel Creation: Once authenticated, a secure channel is established for data transfer.
File Transfer: Files are transferred over this encrypted channel, ensuring confidentiality and integrity.
This process ensures that both the authentication credentials and the data are encrypted, providing a high level of security for file transfers.
