Tips for Server Security

1. Always use cpanel as possible. It allows for easy server admin and saves money from hiring a system admin.
2. Change root port for ssh.
3. Block ports that are not in use
4. Use host access control
5. Turn off root access
6. There are way more tips you can learn from google. Reply to this post and i can offer more tips.

You dont need to use cpanel
Chaging ssh port is good for bots but still easy to find the ssh port
Blocking ports not in use is good
Turning off root access? Not nessassary but you can use ssh key instead of pass

Cpanel is not the only secure panel out there. interworx is just fine also

I'd argue that SSH access for root should be off regardless, you aren't going to use it.

Keys over passes in all cases.
There's a bunch of stuff to do around SSL config if you're serving stuff.

Moving SSH has pros and cons, one one hand if you're using keys and something to block brute force then nothing to worry about but on the other hand bots will be trying to login.

Then obviously review the config of all network services to see what can be done to strengthen security.
