What is the benefit of using SCP over FTP for file transfers?

• A. Faster speeds
• B. Encryption during transfer
• C. Ease of use
• D. Compatibility with older systems

Answer: (B)

Using SCP (Secure Copy Protocol) for file transfers offers the significant benefit of encryption during the transfer. SCP is designed to securely transfer files between hosts on a network, utilizing the SSH (Secure Shell) protocol for secure transmission. This means that not only are the files being sent protected from being intercepted during the transfer, but the authentication process itself is also encrypted, enhancing overall security.

In contrast, FTP (File Transfer Protocol) does not encrypt data. It transmits information, including usernames and passwords, in plaintext, making it vulnerable to eavesdropping and attacks. Therefore, when security is a priority, especially for sensitive data, SCP is the preferable choice.

Other options like faster speeds, ease of use, and compatibility with older systems do not adequately justify the use of SCP over FTP, as these factors can vary based on implementation, user experience, and the specific systems in use.
