Information
RHEL 9 SSH server configuration file must be owned by root.
GROUP ID: V-257998
RULE ID: SV-257998r1082181
Service configuration files enable or disable features of their respective services, which if configured incorrectly, can lead to insecure and vulnerable configurations. Therefore, service configuration files must be owned by the correct group to prevent unauthorized changes.
Solution
Configure the "/etc/ssh/sshd_config" file and the contents of "/etc/ssh/sshd_config.d" to be owned by root with the following command:
$ sudo chown -R root /etc/ssh/sshd_config /etc/ssh/sshd_config.d
