What does SFTP stand for?

• A. Secure File Transfer Protocol
• B. Secure Shell
• C. Secure Sockets Layer
• D. Single Network Management Protocol

Answer: (A)

SFTP stands for Secure File Transfer Protocol, a secure method to transfer files over a network. It runs over SSH, so it uses the SSH layer to provide encryption, authentication, and data integrity for both the commands and the file data being moved. This protects file transfers from eavesdropping, tampering, and credential exposure, unlike traditional FTP which sends data in clear text. SFTP is a distinct mechanism from Secure Shell, which is primarily for secure remote login and command execution; it isn’t just another SSL/TLS web security protocol, and it isn’t a general network management protocol. In practice, you connect to a server via SFTP to securely upload, download, and manage files within an SSH-secured session.
