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.

Check Content

Verify the ownership of "/etc/ssh/sshd_config" and any "/etc/ssh/sshd_config.d/*.conf" files with the following command:

$ find /etc/ssh/sshd_config /etc/ssh/sshd_config.d -exec stat -c "%U %n" {} \;

root /etc/ssh/sshd_config
root /etc/ssh/sshd_config.d
root /etc/ssh/sshd_config.d/40-stig.conf
root /etc/ssh/sshd_config.d/50-redhat.conf
root /etc/ssh/sshd_config.d/clientalive.conf

If any of the files do not have an owner of "root", this is a finding.
