Every time you browse a web page, a series of requests are sent by your browser to the respective web server in the form of data packets. The role of a firewall is to keep a close eye on these data packets and determine if they are safe or not.

The firewall finds the tampered data packets by following the rules which are set up. Depending on these rules, the data packets are either rejected or accepted.
