DevelopmentA developer connects to servers using a secure shell program. The program warns the developer when they connect to a new server and asks that they confirm the IP.

The developer authenticates with each server by logging on with a strong password.
|Overview: Mutual Authentication
A user-machine or machine-machine process of verifying the identity of both sides in an interaction.
