After setting up a fresh Ubuntu 24.04 VPS, the first priority is hardening it before hosting anything public. In this guide, I’ll walk through the essential steps: securing access with SSH keys, disabling password login, creating a non-root sudo user, enabling automatic updates, setting up a firewall, and adding brute-force protection with Fail2Ban.

But I could never quite justify the monthly cost or find the time to manage one. Instead, I stayed busy with virtual machines on my PC and laptop, which kept my curiosity satisfied for a while.
