Fix Recommendation

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

Check Contents

Verify the group ownership of the "/etc/ssh/sshd_config" file and the contents of "/etc/ssh/sshd_config.d" with the following command:

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

root /etc/ssh/sshd_config
root /etc/ssh/sshd_config.d
root /etc/ssh/sshd_config.d/50-cloud-init.conf
root /etc/ssh/sshd_config.d/50-redhat.conf

If the "/etc/ssh/sshd_config" file or "/etc/ssh/sshd_config.d" or any files in the sshd_config.d directory do not have a group owner of "root", this is a finding.
