What is the main purpose of SSH (Secure Shell Protocol)?

• A. To send emails securely
• B. For secure remote logins
• C. To transfer files
• D. For web browsing

Answer: (B)

SSH, or Secure Shell Protocol, is primarily designed to provide a secure method for remote logins to machines over a network. It encrypts the data transmitted during the session, ensuring that sensitive information such as passwords and commands is protected from interception by unauthorized parties. This security feature is essential for system administration, as it allows users to manage servers and devices remotely without exposing their credentials or the data they handle to potential eavesdroppers. While some other options like transferring files can be accomplished using SSH through tools like SCP (Secure Copy Protocol) or SFTP (Secure File Transfer Protocol), the core function and main purpose of SSH is to facilitate secure remote access rather than file transfer alone. Sending emails securely and web browsing are served by different protocols, making them irrelevant in the context of SSH's primary function.
