Which encrypted remote-access tool lets you open a terminal on a server on the other side of the planet and operate it directly?

SSH, or Secure Shell, creates an encrypted connection between your computer and a remote machine, letting you open a terminal session on that distant server and control it directly as though you were sitting in front of it, no matter how far away it physically is. This is what makes managing cloud servers around the world practical and secure, since all commands and data pass through an encrypted channel rather than plain text.

'SOS' and 'TMI' are unrelated acronyms chosen only to rhyme with the real term; neither has any connection to remote server access.

Before SSH became standard, remote access tools sent commands and passwords in plain, unencrypted text, meaning anyone intercepting the connection could read everything, which is exactly the vulnerability SSH's encryption was built to close.
