Fix Recommendation

Configure RHEL 10, for PKI-based authentication, enforces authorized access to the corresponding private key.

Create a new private and public key pair that uses a passcode with the following command:

$ sudo ssh-keygen -N [passphrase]

Check Contents

Note: If the system administrator demonstrates the use of an approved alternate multifactor authentication method, this requirement is not applicable.

Verify RHEL 10 SSH private key files have a passcode.

For each private key stored on the system, use the following command:

$ sudo ssh-keygen -y -f /path/to/file

The expected output is a password prompt:
"Enter passphrase:"

If the password prompt is not displayed, and the contents of the key are displayed, this is a finding.
