Arch Linux Post-Install Guide [Linux Security Tutorial]
Have you been hacked? Linux gets a reputation for being more secure than Windows or macOS. But that's not the whole story. With just 5% of the desktop market, Linux is a smaller target—but not always less vulnerable. If it can happen to a production server, it can happen to your laptop, and you might never even know!
In this video, I walk you through 8 practical steps to secure your Linux system — whether you're on Arch (my daily driver), Ubuntu, Fedora, or another distro. These aren’t extreme hardening techniques — just the fundamentals that every Linux user should understand.
