Securing a cloud server begins with controlling network traffic. Every open port on an internet-facing system is a potential entry point for unauthorized scans and automated exploits.
While tools like iptables or nftables can be complex, UFW (Uncomplicated Firewall) makes managing firewall rules simple and reliable.
In our complete guide, we walk through configuring UFW on Ubuntu 24.04 LTS step by step.
🔑 Key Concepts Covered:
Default Traffic Policies: Setting up deny incoming / allow outgoing.
SSH Lockout Protection: Properly allowing SSH before enabling UFW.
Web Services Setup: Opening HTTP (80) and HTTPS (443) ports.
IP Restriction Rules: Restricting port access to specific static IP addresses.
Rule Cleanup: Finding numbered rules and safely deleting them.
