Use SSH key pairs to log on to Linux instances

Evaluates whether SSH key pairs are used to log on to Linux instances. Compliant if key pair authentication is enabled.

Scenarios

SSH key pairs apply only to Linux instances. A key pair consists of a public key and a private key, providing secure passwordless authentication.

Default risk level: medium.

You can change the risk level when you apply this rule.

Compliant: An SSH key pair is used to log on to the Linux instance.
Non-compliant: No SSH key pair is used. To fix this, follow the Incompliance remediation steps.
