Which secure protocol is recommended for remote access?

The recommendation for using SSH, or Secure Shell, for remote access is grounded in its ability to provide a secure channel over an unsecured network. SSH encrypts the data being transmitted, ensuring confidentiality and integrity, which is essential when accessing remote systems.

Unlike Telnet, which transmits data in plain text, making it susceptible to interception and attacks such as eavesdropping, SSH protects the data through encryption. This makes SSH particularly valuable for accessing servers, managing network infrastructure, or any service that requires secure remote administration.

Furthermore, while FTP (File Transfer Protocol) and HTTP (Hypertext Transfer Protocol) are widely used protocols, they are also not secure on their own as they do not encrypt the data being transferred. There are secure counterparts, such as SFTP (which builds on SSH and provides secure file transfer), but when it comes specifically to remote access for command-line interfaces and system administration, SSH stands out as the most secure and widely accepted choice.

In summary, SSH is the preferred choice for remote access due to its robust encryption capabilities, which protect user credentials and sensitive data during transmission.
