Linux Firewall Antivirus

Download Linux Firewall Antivirus

Linux-based computers are highly secure, and it is very difficult to introduce threats such as malware, spyware, and ransomware unless the user attempts to engage in opening phishing emails or accessing insecure sites.Do I need a firewall on Linux? Every Linux desktop user may have this question in mind. Adding an extra firewall to the secured OS will keep your system and the data stored in it even more secure from threats. Linux Firewall Antivirus has an inbuilt firewall that is inactive by default. It can be activated using the below-mentioned steps.

UFW firewall:

  • If you have a Graphical Interface, you can install the UFW firewall without any difficulties.
  • On your Linux desktop, launch the software manager and install the GUFW program.
  • After installing the GUFW program, enable it to activate the UFW firewall.
  • By default, the settings are set to deny incoming and allow Outgoing connections.
  • If you wish to set your desired firewall rules or open ports, click the Rules tab on the GUFW program and open ports for the specific program you want to control from the outside.

  • To activate the firewall, type the “sudo ufw enable” command in the Terminal window.
  • To check the status, enter the “sudo ufw status verbose” command.
  • Now, the UFW firewall will be activated with the default settings.

  • To check the status, enter the “run man ufw” command.
