Firewall

Summary

A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

Detailed Description

Firewalls can be hardware-based, software-based, or a combination of both, and they serve as a barrier between trusted and untrusted networks. They analyze data packets and determine whether to allow or block them based on specific security criteria or rules set by the network administrator. Firewalls are essential in protecting networks from unauthorized access, cyber attacks, and other types of malicious traffic.
