How to properly secure my WordPress installation?

I’m currently on my own server (fredericpilon.com) with my own website.

WordPress being kind of a big shot of CMS, it may be targeted by hacks.

Any tips and tricks on how to properly secure my WordPress installation from said hackers and evil-doers?
