SSH
SSH (Secure Shell) is an encrypted protocol for securely logging into and administering remote servers.
SSH is how teams manage servers; if the SSH port stops responding, you have lost remote access — often the first sign of a server problem. SSH monitoring checks the service answers on its port so you find out before you need to log in urgently.
