A properly configured firewall is one of the most important layers of security for any internet-facing server. UFW (Uncomplicated Firewall) is a user-friendly front-end for managing iptables rules that ships pre-installed on Ubuntu. Its defaults are sensible: block all incoming connections, allow all outgoing connections. No outside traffic reaches your server unless you explicitly open a port. This guide covers how to configure a UFW firewall on Ubuntu 18.04, from setting default policies and application profiles to writing allow and deny rules for specific ports, IPs, and subnets. <strong>Prerequisite:</strong> You need sudo access.
