Well it’s probably the most relevant reference of a hardware-based version of the firewall that most of us have ever witnessed in real life. I am sure we all remember the famous scene from Mission Impossible: Ghost Protocol where IMF agent Ethan Hunt (Tom Cruise) climbs the iconic Burj Khalifa to disable the firewall security system of the hotel. There are two types of firewall programs viz appliance firewall and client-based firewall. When a firewall system checks a data and finds it to be in compliance with the rules of data packets, only then it approves those data packets to travel through, otherwise it rejects them. So, what firewall software does is- monitor the data that’s being transferred to your system constantly to block data-based malware threats. In the cyber world, data transfers happen between the Windows PC and the servers & routers. As soon as a Windows machine gets connected to the internet or LAN, it immediately becomes vulnerable to millions of malicious programs and cyber exploiters lurking in the cyber space just in a matter of a few seconds or minutes. The internet is a hub of malicious programs.
