What security measures did everyone use when configuring and can Ansible manage multiple installs?

I have a basic firewall, but did not use App Armor, SELinux, or kernel blacklists. I definitely shut down port 22 just for now. It's just a laptop daily driver. Should I do more?

Also, I'm now addicted to Arch. I'm using Hyprland with it. This means I've got two bleeding edge wares and that gets rough sometimes when things break. I want Arch on my desktop gaming rig though. I tired other distros but I just love Arch. Has anyone tried using Ansible to manage multiple installations? I really can't maintain two so I was wondering if Ansible would make it easier, especially for updating.
