Introduction :
A firewall is a network security device that is designed to prevent unauthorized access to a network by filtering incoming and outgoing network traffic based on a set of predefined rules. The term "firewall" originated from the construction industry, where a firewall is a barrier designed to prevent the spread of fire between buildings. In the context of network security, a firewall serves a similar purpose by preventing the spread of security threats between different parts of a network.
