Hi, In order to disable the Root SSH Access I edited the ssh_config file present at the root directory /etc/ssh/ssh_config and pasted the value PermitRootLogin no correctly in this file which restricts the Root SSH Login access and then restarted the sshd service to bring in the effects. I did this on all the App Servers correctly but when finally submitted the task, I was told the task was failed but everything was done correctly.
You have to apply this procedure in sshd_config instead of ssh_config.
