In this lab, your task is to perform the following: You also want to allow all traffic from the LAN network to the DMZ network. You need to configure the perimeter firewall on the network security appliance (pfSense) to allow access to the web server from the LAN and from the WAN. You recently placed a web server in the demilitarized zone (DMZ). You work as the IT security administrator for a small corporate network. > A firewall can impede network availability because it adds processing to network traffic or might drop network traffic when overloaded. > Firewalls don't offer protection against all attacks (for example, spoofed email messages). > Firewalls can protect against external attacks. The action to take when the traffic matches the filter criteria. Packet information, such as the source or destination IP address or port number. The direction of traffic (inbound/outbound). The interface to which the rule applies. A rule identifies traffic characteristics, such as: > Firewalls use filtering rules, sometimes called access control lists (ACLs), to identify allowed and blocked traffic. A host-based firewall can be configured to meet the security requirements of the specific host and add an additional layer of security even when a network firewall has been implemented. Host-based firewalls are typically software programs. ![]() Use a host-based firewall to protect against attacks when there is no network-based firewall, such as when you connect to the internet from a public location. ![]() > A host-based or application based firewall inspects traffic received by a host. Network-based firewalls are typically dedicated hardware devices. For example, you can install a network-based firewall on the edge or your private network that connects to the internet to protect against attacks from internet hosts. > A network-based firewall inspects traffic as it flows between networks. A firewall is a device or software running on a device that inspects network traffic and allows or blocks traffic based on a set of rules. ![]()
