Configuring SSH - disallow host based authentication

高レベル 1手動レビューibm-i

説明

The recommendation is to edit the /QOpenSys/QIBM/UserData/SC1/OpenSSH/etc/sshd_config file to ensure that host- based authentication is disallowed. Using host-based authentication, any user on a trusted host can log into another host on which this feature is enabled. Since this feature depends only on system authentication and not on user authentication, it must be disabled.
