Security blindspots for selfhosted website (lemmy.world)

Hello. I’m pretty new here. I just managed to get my Raspberry Pi setup at home to selfhost a simple website that will act as my portfolio for some art I do.

I’m using WordPress to make the content of the website, meaning it runs on Apache, MariaDB and MySQL in the background. It’s connected via port 80 since I don’t want to pay for SSL certificates to setup https. There will be no accounts or transactions happening on my website. I don’t have anything to manage my dynamic IP but I’ll figure that out later. I’ve deleted the default Pi user on the RPi.

Are there security issues I should address preemptively? I’m worried for instance that I am exposing my home network, making it easier for someone to breach into whatever is connected there.

Any tips on making sure my setup is secure?

Alright everyone, thank you so much for your thoughtful recommendations! To sum it up, here's what I have done:

I used let's encrypt's Certbot to get my SSL certs and setup https, auto-renew every 3 months and I setup a reminder to update Certbot every month.
I setup a permanent redirect from http to https in Apache
I installed a firewall on the Pi, only 80, 443 and [22 from my computer to the RPi] are open. I couldn't find the firewall settings on my router but I assume they exist since I had to forward 80 and 443 there.
installed the following plugins: WordFence and WP Fail2Ban
changed the user password on the pi to a better longer one

I think I should be all set, shouldn't I?

You may want to consider dockerizing your services just for maintainability and isolation from your host. I recommend something like Nginx Proxy Manager to serve as the "main entrance" for your docker network and to handle Let's Encrypt for you.

I second this. I didn't understand that until....you know, like you install the latest python or something and then your website is proof! Gone. Dockerization gives it a little bit of stability.
