Hands-On Lab Training for CompTIA Security+ | pfsense + firewall + rules
Показать описание
In this lesson, we'll continue with the installation and configuration of pfSense. More specifically, we will implement firewalling.
Our mission is simple: restrict the 172.16.1.0/16 network from pinging 8.8.8.8, but allow ICMP traffic to/from other hosts. In this fake scenario, we are going to act as if we received a complaint from the owners of Google’s DNS, and they asked us to restrict ICMP traffic from the pings from 172.16.1.0/16. This is part of the "putting it all together" set of tasks. So, what is Firewalling?
► What: Firewalling refers to the process of implementing and managing a network security system using the pfSense open-source firewall distribution.
► Who: Network administrators and IT professionals are responsible for configuring and managing the pfSense firewall.
► When: Firewalling is an ongoing process that needs to be in place whenever the firewall is active, typically whenever the network is operational.
► Where: The firewall is deployed on the network's edge or at strategic points within the network to control the flow of traffic between different network segments.
► Why: The main purpose of firewalling is to enhance network security by regulating incoming and outgoing traffic, protecting against unauthorized access, and preventing malicious attacks.
► How: Firewalling in is achieved through the configuration of rules, which define what types of traffic are allowed or denied based on specific criteria such as source and destination IP addresses, ports, and protocols. This enables the firewall to inspect and control network traffic effectively. The rest of the "how" is what this video is all about, so let's get into it!
