Information

RHEL 9 SSH server configuration file must be group-owned by root.

GROUP ID: V-257997
RULE ID: SV-257997r1069370

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 group-owned by root with the following command:

$ sudo chgrp root /etc/ssh/sshd_config /etc/ssh/sshd_config.d
