Configure RHEL 8 to stop users from logging on remotely as the "root" user via SSH.
Edit the appropriate "/etc/ssh/sshd_config" file to uncomment or add the line for the "PermitRootLogin" keyword and set its value to "no":
PermitRootLogin no
The SSH daemon must be restarted for the changes to take effect. To restart the SSH daemon, run the following command:
$ sudo systemctl restart sshd.service
Verify remote access using SSH prevents users from logging on directly as "root".
Check that SSH prevents users from logging on directly as "root" with the following command:
$ sudo /usr/sbin/sshd -dd 2>&1 | awk '/filename/ {print $4}' | tr -d '\r' | tr '\n' ' ' | xargs sudo grep -iH '^\s*permitrootlogin'
PermitRootLogin no
If the "PermitRootLogin" keyword is set to any value other than "no", is missing, or is commented out, this is a finding.
If conflicting results are returned, this is a finding.
