Four-layer network security devices

A firewall is a Layer 4 security device that protects the network perimeter by filtering traffic based on IP addresses, ports, and protocols. Network security involves tools, techniques, and policies to protect digital assets from unauthorized access and cyber threats. It combines hardware, software, and expert resources to ensure network integrity and prevent breaches. By employing multiple graded protection stages, potential unauthorized access and data breaches can be diffused. In this lesson, we examine the network firewall - a security device that operates at Layer 4 of the OSI model and guards the perimeter of the network. The following diagram shows the most common icons used to visualize a Cisco firewall in the network topology.
