Secure Linux centos 7 vps

Hi, I have Vps. I want that you secure it by changing root user, disable ssh password login, change ssh port, firewall, limited access to user, email on file change, IP address filter (only limited IP address can access) and more basic things.

you have to do this all work through teamviewer. I have many clients and need to secure their server so it can be a long term job.
