My .htaccess file seems quite ’empty’?

Hi there,
This is my first post, and im not IT savvy, so please go easy with me.

I’ve recently set up my website https://www.confusedcanines.co.cc and have gone with wordpress as being the most intuitive for my needs. I installed wordpress into a sub-folder from root (called wp).

I read about changing the default URL by dropping the .htaccess file and index.php in the root directory (which I have done). While doing this, I had a look inside the .htaccess file, and noticed that while there was some blurb there, it didnt seem to limit access to any part of site? I dont get any warning or error messages on my dashboard, so do I need to add something in here? I feel like I’m vulnerable to outside attack?

Any advice?
