Yeah, people will always try to brute force there way into your servers.

Digital Ocean has a good guide on how to initial setup a server which covers securing SSH further than the default.

https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-16-04

Key Points

  • Use Public Key Authentication
  • Create a new user and disallow root login
  • Install Fail2Ban

You could change your SSH port but there is a bit of debate around that and personally, I leave it as default.
