A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and an untrusted external network, such as the Internet.


A properly configured firewall can help prevent unauthorized access to a network, protect against malware and other types of cyber attacks, and ensure that sensitive data remains private. Therefore, firewalls play an essential role in network security by providing a first line of defense against potential threats.
