  • 2855

The very first thing you should do after logging into your VPS is secure it.
A firewall helps protect your server from unauthorized access and attacks.

Here’s what you should enable right away using UFW (recommended for beginners):


???? 1. Install UFW

 
apt install ufw -y

(Works on Ubuntu/Debian)


???? 2. Allow SSH

 
ufw allow 22/tcp

???? 3. Allow Web Traffic (if hosting a website)

 
ufw allow 80/tcp ufw allow 443/tcp

???? 4. Enable the Firewall

 
ufw enable

???? 5. Check Status

 
ufw status

???? Optional but recommended:

  • Change your SSH port

  • Disable root password login

  • Enable fail2ban

Taking 2 minutes to set this up can save you from attacks later.
