ufw (Uncomplicated Firewall)
A frontend for managing firewall rules in Linux, providing an easy interface for common firewall operations while allowing access to more complex configurations.
What is Ufw?
ufw (Uncomplicated Firewall) is a frontend for managing firewall rules in Linux operating systems. It aims to provide an easy interface for most common firewall operations while still allowing access to more complex configurations.
Some key features of ufw include:
- Simple command line interface for enabling/disabling the firewall, opening/closing ports, etc.
- Default deny policy to provide basic security out of the box
- Integration with common services to automatically open ports when services are installed
- GUI frontend available (gufw) for basic management
- Support for IPv6 in addition to IPv4
- Backed by iptables, netfilter for robust firewall capabilities
ufw is not a full-fledged firewall solution on its own but rather a user-friendly way to manage iptables rules. It is installed by default on Ubuntu and aimed at Linux users who want a basic firewall without dealing with complex iptables syntax. Experienced admins may still directly interface with iptables for finer-grained control.
