Please be kind! I am a self-taught Linux user and by no means an expert. My goal with this guide is to help newcomers to Linux have an easier and more secure start.

To all the experts out there, please be kind and do share your tips and observations. I am happy to keep updating the article to make the self-hosting world more secure.

Great guide. Agree with disable IPv6, extra unnecessary exposure and firewall effort. Consider Automatic updates, review ports/disable unwanted services.

Automated security updates (unattended updates), netstat -ap --numeric-ports (for process review)

Also consider that debian is the downstream distribution of ubuntu, its usually older but more stable. More stable => less bugs => more secure
