What protocol adds security to remote connections?

• A. HTTPS
• B. SSH
• C. FTP
• D. TFTP

Answer: (B)

The correct choice for adding security to remote connections is SSH, or Secure Shell. SSH is a protocol designed to provide a secure channel over an unsecured network in a client-server architecture. It encrypts the data transmitted between the client and the server, ensuring that sensitive information, such as usernames and passwords, cannot be intercepted by malicious users. SSH is commonly used for secure remote administration of network devices and for secure file transfers. Its encryption and authentication features make it a preferred choice for system administrators who need to manage servers securely over an untrusted network. In contrast, HTTPS is primarily used for secure communication over the internet, specifically for web traffic, while FTP (File Transfer Protocol) and TFTP (Trivial File Transfer Protocol) are both used for file transfers but do not provide built-in security features. FTP transmits data in plain text, which makes it vulnerable to eavesdropping. TFTP, while simpler, also lacks security measures, making it unsuitable for secure remote connections.
