# For this section, you will still be using your '''centos1''' and '''centos2''' VMs.
# Think of a good quality password and change your root passwords on all 3 VM's to be more secure. (It would be a good idea to do this for non-root accounts also)
# The next change you can make is to prevent the root account from logging in to sshd altogether.# Change to your centos2 VM and open a terminal.
# Edit the file '''/etc/ssh/sshd_config''' and look for the option '''>PermitRootLogin'''. Uncomment the option (or add the option if it does not appear) and change the option value to '''"no"'''.
# Even better, it is possible to restrict access to just specific users that require it.
