Q # 1) What is a firewall?

The purpose of installing a firewall on a computer, phone, or tablet is to protect users from data-driven malware threats on the Internet or other connected networks.

The firewall achieves this by examining the data packets based on the defined rules. If the data packets comply with these rules, the firewalls accept them. If they don’t comply with the rules, the firewall rejects or blocks them.

Today, firewalls help protect computers and other connected devices around the world, whether they belong to individual users, large corporations, or the government.

Q # 2) How does a firewall work?

Answer: Put simply, firewalls monitor traffic to accept or allow “good data” while rejecting or blocking “bad or harmful data”. However, if we go into detail, the firewall uses one of three methods, or combinations thereof, to control traffic that is entering and exiting the network.
