About network security, the best Linux firewalls are all about. If someone gets into your network without your permission, they can see what you do on the internet and maybe even take over your devices or, worse, your virtual identity.

The best Linux firewalls make managing firewall security on Linux computers and IT networks simple and easy. A dedicated firewall stands between the internet and your internal network and cleans all traffic before it gets there. Having a firewall to protect against unauthorised access is a basic part of cybersecurity. Every IT system needs to be safe. Cyberattacks can be aimed at online servers just like they can be aimed at home computers.

You’ll need a way to keep hackers and other people who shouldn’t be there out. When this happens, firewalls help. What is the best Linux firewalls, in a few words? It separates a computer from the “outside world.” A firewall is a piece of software or hardware that keeps people who shouldn’t be on a network from getting on. It uses a set of rules to look at incoming and outgoing traffic to find and stop threats.

Over 75% of the world’s servers are run by Linux, so these solutions are important for keeping users and end consumers safe. Let’s start by explaining what Linux is so we can better understand how a Linux firewall works. The most popular and well-known open-source operating system is Linux. Linux is an operating system that is at the bottom of a computer. It takes requests from other program and sends them to the hardware. Below we have mentioned some of the best Linux firewalls.

Iptables is a firewall that comes with best Linux firewalls. It is not the most feature-rich firewall out there, but it is a safe one. Iptables doesn’t have a user interface because it is a command line tool. You have to learn the commands in order to set it up, so it’s not the easiest thing to use. But there are graphical user interfaces (GUIs) that work with iptables to make it easier to use, like Ubuntu’s “Uncomplicated Firewall.” Iptables is easy to understand because all it does is look at the packets and see if any of the rules match.

If it doesn’t find any, it just does what it does by default. Iptables is just “good enough” as a firewall. If you want a firewall with lots of features and bells and whistles, this is not it. But Iptables will work fine if you want something simple that you can set up and then forget about. If you like this app you can get it from official website.
