SFTP (SSH File Transfer Protocol) is used for secure file transfer and management over a network, utilizing the SSH (Secure Shell) protocol to encrypt data transmissions and authenticate users. It provides a secure method for transferring files between client and server systems, protecting data confidentiality and integrity against eavesdropping and unauthorized access. SFTP is commonly employed in environments where data security is paramount, such as transferring sensitive files, backups, software updates, and configuration files securely over untrusted networks or the internet.
SFTP is preferred over FTP (File Transfer Protocol) in scenarios where data security and protection are critical considerations. Unlike FTP, which transmits data and authentication credentials in plain text, SFTP encrypts all data transmissions and commands, ensuring confidentiality and preventing interception by malicious parties. Organizations and individuals choose SFTP for tasks requiring secure file transfer, remote file management, and compliance with security standards and regulations governing data protection.
The main difference between FTP and SFTP lies in their security mechanisms and implementation. FTP operates over plain text and lacks inherent encryption, making it susceptible to interception and unauthorized access. SFTP, on the other hand, leverages SSH to establish secure connections, encrypt data transmissions, and authenticate users using cryptographic keys or passwords. This security enhancement makes SFTP suitable for transferring sensitive information and performing remote file operations securely over networks.
The SFTP put command is used to upload files from the client system to the remote server. When a user initiates an SFTP session and navigates to the directory where files are stored on the client system, they can use the put command followed by the filename to transfer the specified file to the server. This command ensures that the selected file is securely transmitted over the encrypted SFTP connection and stored on the remote server’s designated directory. The put command is essential for uploading files, enabling users to transfer data securely and efficiently between local and remote systems using the SSH File Transfer Protocol.
