Simple File Transfer Protocol (SFTP) is a network protocol used for transferring files between a client and a server on a computer network. However, it’s essential to note that there is some confusion in terminology between “SFTP” and “Simple File Transfer Protocol,” and the terms are often used interchangeably, even though they refer to different protocols. Here’s an explanation of both:
- SFTP (Secure File Transfer Protocol):
- Definition: SFTP, as mentioned earlier, is Secure File Transfer Protocol, and it’s an extension of the SSH (Secure Shell) protocol. It is used for secure file transfers and file management over a secure connection.
- Security: SFTP provides strong security features, including data encryption and secure authentication, making it a reliable choice for secure file transfers.
- Simple File Transfer Protocol:
- Definition: The Simple File Transfer Protocol (not to be confused with SFTP) is an older, non-standard protocol used for simple, unsecured file transfers over a network. It was originally designed for low-complexity and easy implementation but lacks the security features of SFTP.
- Security: Simple File Transfer Protocol is not considered secure and is rarely used in modern network environments. It sends data and credentials in plaintext, making it susceptible to interception.
In practice, when people refer to “SFTP,” they often mean the Secure File Transfer Protocol, as it is the more widely used and secure protocol for transferring files over the internet and networked environments. If you need to transfer files securely, it’s recommended to use the Secure File Transfer Protocol (SFTP) rather than the older, unsecured “Simple File Transfer Protocol.”
