Fix Recommendation

Configure the SSHD config files to have "0600" permissions with the following command:

$ chmod 0600 /etc/ssh/sshd_config /etc/ssh/sshd_config.d/*.conf

Check Contents

Verify the permissions 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 "%#a %n" {} \;

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

If any of the files do not have "0600" permissions, this is a finding.
