Uncomplicated Firewall (UFW) is a user-friendly firewall management tool. Enable UFW and configure it to allow only necessary traffic:

sudo ufw enable
sudo ufw allow ssh
sudo ufw allow 80/tcp # HTTP (if you are running a web server)
sudo ufw allow 443/tcp # HTTPS (if you are running a web server)
sudo ufw deny out smtp #Prevents the server from sending email
sudo ufw deny out 25 #Prevents the server from sending email
sudo ufw enable

This will enable the firewall and allow SSH, HTTP (port 80), and HTTPS (port 443) traffic. Enable and verify UFW to prevent the most common attacks according to CrowdSec security firm in the 2024 report.

4.3. Set Up SSH Keys

Using SSH keys instead of passwords enhances security. Generate an SSH key pair on your local machine:

ssh-keygen -t rsa -b 4096
