Secure Shell (SSH) is a protocol that provides a secure channel over an unsecured network, like the internet, by using a client-server architecture. SSH offers strong authentication and secure encrypted data communications, making it the appropriate choice for remote server management. This makes it a suitable protocol for tasks that require security, such as remote server administration. Telnet, on the other hand, is not secure and transmits data, including passwords, in plaintext. Remote Desktop Protocol (RDP) is primarily used for remote access to graphical Windows desktops and may not be the most secure option for server management, and will not support Linux systems natively. Hypertext Transfer Protocol Secure (HTTPS) is generally used for secure communication over a computer network within a web browser and is not tailored specifically for server management.
