Here is the importance of Firewall Service in Ubuntu. How these are essential security tools that protect your computer from viruses and hackers.
Firewall Service in Ubuntu
Ubuntu is one of the most versatile and widely used Linux-based operating systems. This OS is a Debian-based OS that is widely used by big companies, small businesses, or home users. It is the best platform to start with Linux.
So, the Ubuntu Firewall service is quite important for every user who uses Ubuntu as their primary and secondary OS. Nowadays, there has been an increasing number of Linux viruses running on your computer and hackers trying to gain access to your computer. They are continuously trying to either steal your data or inject some malicious code into your PC.
To protect yourself from such attacks, there are certain steps that you need to follow. Also, the firewall service in Ubuntu helps you in protecting your PC from any kind of virus or hacker attack. It blocks all incoming requests from unknown computers and networks.
You can build a firewall on any version of the Ubuntu operating system using UFW. It stands for Uncomplicated Firewall. UFW stands for Uncomplicated Firewall, which has been developed by Marc Lehmann at Progeny Linux Systems (A Mandriva Company).
Uncomplicated Firewall
UFW is included by default in all versions of the Ubuntu operating system. Here are the steps that you need to follow to enable a firewall on your Ubuntu PC. The first thing that you need to do is open up your Terminal window by pressing Ctrl+Alt+T.
Then run this command: sudo ufw allow ssh. This command will allow SSH connections on your computer. It is needed for remote login through Secure Shell (SSH).
When you get asked whether you want to continue connecting or not, type y and hit Enter. Now type this command: sudo ufw enable. So, this command enables the firewall services on your computer and configures it so that it can be accessed through the Terminal window.
Now type this command: sudo ufw status verbose. This command shows info about the UFW status and allows you to view both forwarded and denied requests. And finally, type this command: sudo ufw default denies incoming.
Moreover, this command sets the default rules for incoming connections. It does not allow any incoming requests by default. This prevents any unwanted access to your computer from outside.
