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.

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.
