Which protocol is commonly used for securely transferring files over a network?

• A. FTP
• B. HTTP
• C. SFTP
• D. Telnet

Answer: (C)

The protocol commonly used for securely transferring files over a network is SFTP, which stands for Secure File Transfer Protocol. SFTP provides a secure mechanism for transferring files by leveraging secure shell (SSH) encryption. This ensures that both the data being transferred and the authentication credentials remain confidential and are protected against eavesdropping or interception during transit. In contrast, other protocols such as FTP (File Transfer Protocol) lack built-in security features, making them susceptible to attacks and data breaches. HTTP (Hypertext Transfer Protocol) is primarily used for transferring web pages and does not provide built-in encryption or security for data transfer. Telnet is another protocol used for text-based communication over a network, but, like FTP, it transmits data in plain text without encryption, which poses security risks. Therefore, SFTP is the recommended choice for secure file transfers due to its robust encryption capabilities.
