SFTP Server
An SFTP (SSH File Transfer Protocol) server is a secure file transfer service that runs over the SSH (Secure Shell) protocol, enabling encrypted file transfers and remote file management. It provides a secure alternative to traditional FTP by encrypting both commands and data, protecting against eavesdropping and tampering. SFTP servers are commonly used for automated file transfers, backup systems, and secure data exchange between systems.
Developers should learn and use SFTP servers when they need to securely transfer files in environments where data confidentiality and integrity are critical, such as in financial, healthcare, or compliance-driven industries. It is essential for automating file uploads/downloads in CI/CD pipelines, managing web server deployments, or handling sensitive data backups, as it eliminates the security risks associated with plain-text protocols like FTP.
