Which abbreviation is the Secure File Transfer Protocol?

• A. SSL
• B. SMTP
• C. SFTP
• D. SID

Answer: (C)

SFTP stands for Secure File Transfer Protocol. It’s a file transfer method designed to securely move files by encrypting both the commands and the data through SSH. This makes SFTP far more secure for file transfers than traditional FTP, which transmits data in the clear. It’s distinct from SSL, which is a security layer used to protect channels (as in HTTPS or FTPS), and from SMTP (mail delivery) or SID (not a standard file-transfer protocol). SFTP typically runs over SSH (often on port 22), using SSH authentication to protect access.
