Setting up a personal site on local hardware has been on my bucket list for along time. I finally bit he bullet and got a basic website running with apache on a Ubuntu based linux distro. I bought a domain name, linked it up to my l ip got SSL via lets encrypt for https and added some header rules until security headers and Mozilla observatory gave it a perfect score.

Am I basically in the clear? What more do I need to do to protect my site and local network? I’m so scared of hackers and shit I do not want to be an easy target.

I would like to make a page about the hardware its running on since I intend to have it be entirely ran off solar power like solar.lowtechmagazine and wanted to share technical specifics. But I heard somewhere that revealing the internal state of your server is a bad idea since it can make exploits easier to find. Am I being stupid for wanting to share details like computer model and software running it?

    This is dangerous advice because docker is well-known for undoing UFW’s iptable rules. It’s mitigated by binding to localhost, but still way too easy for people to shoot themselves in the foot by using the two together.

      Docker is going to undo your port iptable rules with or without ufw

      Running rm -rf ~ isn’t that hard to do either just don’t do it.

      Your router’s NAT should save you if that happens on the wrong port anyway.

        You shouldn’t suggest UFW at all then. There are other firewall options that can be used just fine with docker.

        It does have real potential to cause issues, e.g. if OP were to put their server in DMZ mode on their router and later copy some docker setup instructions that don’t explicitly bind to localhost.

          Please tell me more, which firewall would you recommend that plays nice with Docker?

          No NAT? Hahaha that’s a big if, and why would you copy paste a docker compose without reading it?

            Firewalld

            No NAT?

            Another user in this thread suggested DMZing, so combine your advice with theirs and boom. It’s not uncommon, and it’s fine if you firewall the box yourself. Most people don’t knowingly choose to use a firewall that they don’t intend to work, like you would.

            why would you copy paste a docker compose without reading it?

            There’s more than one way to use docker. Spinning up an official mysql image using the official docker run OR docker compose calls suggested by the docs would start up a server wide open to the entire internet if DMZ’d.
