If you’ve ever worried about someone sneaking into your computer or server from the internet, you’re not alone. Think of your device like your home, would you ever leave your doors unlocked, especially at night? Of course not! The same logic applies to your Ubuntu system. The UFW Firewall acts like a security guard at your door, allowing only trusted visitors in and blocking unwanted intruders.
In this guide, I’ll walk you through how to set up the UFW Firewall on Ubuntu in a simple, friendly, and easy-to-follow way. No complicated jargon, just practical steps that even a beginner can follow comfortably.
What is UFW and Why Use It?
UFW (Uncomplicated Firewall) is a simple and user-friendly tool built for Ubuntu to help you control what traffic enters or leaves your system. Unlike complicated firewalls with hundreds of commands, UFW keeps things clean and beginner-friendly.
So why should you use it?
Because the internet isn’t always safe. Hackers and bots constantly scan IPs looking for weak systems. UFW acts as your system’s shield, stopping them in their tracks.
Benefits of Using UFW on Ubuntu
Using UFW brings several advantages that make your server or computer safer:
- Easy to Use: You don’t need to be a Linux expert.
- Improves Security: Blocks unwanted access attempts instantly.
- Customizable: You can allow or deny only specific traffic.
- Lightweight: Doesn’t slow down your system at all.
Imagine having a smart bouncer at a club door, letting in guests on the VIP list, but keeping troublemakers away. That’s exactly what UFW does.
How UFW Works (Simple Explanation)
To put it simply:
- Allow rules = “Let this traffic in”
- Deny rules = “Block this traffic”
- If no rules match, UFW blocks by default when active.
Think of UFW as a checklist at the entrance gate. If someone’s name is not on the allowed list, they stay out.
