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?
Let’s Encrypt is good practice, but IMO if you’re just serving the same static webpage to all users, it doesn’t really matter.
Given that it’s a tiny raspi, I’d recommend reducing the overhead that WordPress brings and just statically serve a directory with your site. Whether that means using wp static site options, or moving away from wp entirely is up to you.
The worst case scenario would be someone finding a vulnerability in the services that are publicly exposed (Apache), getting persistence on the device, and using that to pivot to other devices on your network. If possible, you may consider putting it in a routing DMZ. Make sure that the pi can only see the internet and whatever device you plan to maintain it with. That way even if someone somehow owns it completely, they won’t be able to find any other devices to hack.
