Uncomplicate your firewall configuration with UFW
Keep It Simple
UFW takes the complexity out of iptables, which is great for beginners and is even good for experienced users who want to keep it simple and avoid hidden mistakes.
Uncomplicated Firewall (UFW) [1] is a user-friendly front end for managing rules for the iptables [2] firewall system built into Linux. The main goal of UFW is to simplify the process of configuring a firewall for users of all experience levels without compromising the integrity and security of the system it protects. UFW is used in various Linux distributions, particularly Debian-based systems like Ubuntu.
UFW operates by abstracting the complexity of iptables and providing a simpler command-line interface. It comes with reasonable default settings and has support for IPv6. Moreover, UFW allows for easy management of both simple and complex network rules, which makes it highly adaptable to various security needs.
UFW allows administrators to enforce policies and control traffic flow into and out of the network. Proper configuration of UFW can help prevent common security threats such as port scanning, DDoS attacks, and unauthorized remote access.
