This video is about the topic Firewall which is deeply explained in this video and helpful for your exams.
A firewall is a network security device designed to monitor, filter, and control incoming and outgoing network traffic based on predetermined security rules. The primary purpose of a firewall is to establish a barrier between a trusted internal network and untrusted external networks.

Firewalls come in both hardware and software forms, and they work by inspecting data packets and determining whether to allow or block them based on a set of rules. Organizations can configure these rules to permit or deny traffic based on various criteria, such as source and destination IP addresses, port numbers, and protocol type.
