CONCEPT MODELS

See the lesson as a system

Use these visual guides to connect the key ideas before answering the questions.

From SSH endpoint to Server configurationConnect ssh endpoint with host key trust, user key pair, and server configuration.
From SSH endpoint to Server configurationA learning path connects four specific concepts used in configure ssh client and server basics and states the outcome of each one.
SSH endpointClient targets the intended remote account
Host key trustRemote server identity is deliberately trusted
User key pairServer can verify possession of the private key
Server configurationValidated policy is ready for activation
Safe access test: command and checksConnect safe access test with the starting command, expected result, and specific safety boundary.
Safe access test: command and checksA practical check connects safe access test to the relevant command, expected evidence, and caution.
Safe access testFocus on safe access test
Starting commandOpen a second ssh user@host session
Expected resultNew policy works without losing recovery access
Safety boundaryDo not close the sole working session early
