Firewalls Network firewalls protect an entire network by guarding the perimeter of that network. Network firewalls forward traffic to and from computers on an internal network, and filter that traffic based on the criteria the administrator has set. Network firewalls come in two flavors: hardware firewalls and software firewalls.

CompTIA Security+ Exam: Devices, Media, and Topology Security Understanding the Concepts of Security Topologies. The concepts of security topologies are based on firewalls and their application to specific network design scenarios. Topologies consist of hardware devices and security zones that are created with these devices. The remainder of this chapter provides an overview of how firewalls are used to segment the network into security zones and create various security topologies.

Configuring Firewalls A firewall is a set of rules used to protect the resources of your LAN. These rules filter the packets arriving at the router. If a packet does not meet the criteria specified in the rule, it is dropped. If it does meet the criteria, it is allowed to pass through the interface that the rule is applied to. This wizard enables you to create a firewall for your LAN by answering prompts in a set of screens.
