A Firewall can be best defined as advanced network security software or hardware that is exclusively designed and developed to protect computer systems from viruses, hackers and worms. A Firewall protects your laptop and PC from possible threats over the internet. Threats that can damage your computer at the same time access & manipulate your private business data freely.

So we can’t deny the fact the importance of installing a Firewall. You will have a peace of mind that your business data and computer systems are well protected. Here, it is important to note that Windows versions like Windows 8, Windows 7, Windows Vista, Windows XP SP2, and other higher versions come with a built-in Firewall which can be activated on the PC by default.

Now that you know about the function of a Firewall, let us now discover how it works. A Firewall works to filter the information flowing between the internet and your PC.

This mechanism ensures that your PC can only receive and send allowed and authorized data in the process. In other words, just filtering out unauthorized data packets and information. Additionally, it also hides your PC’s IP so that your system is not easily prone and found on the internet by malicious programs and viruses.

Firewalls can also be installed and run on servers for security purposes, helping block traffic that may otherwise damage your systems.
