Description

Cyber attacks are hitting our networks daily, and some of them have become very advanced. Traditional firewalls can be used in order to help the process of detecting and blocking them. In this course, Network Analysis with pfSense, you’ll cover how to utilize pfSense to protect and detect against common attack and exfiltration techniques in an enterprise environment. First, you’ll demonstrate how to setup a decoy VPN server using pfSense to detect compromised accounts. Next, you’ll operate pfSense to block the use of alternate protocols by blocking unnecessary ports and protocols. Finally, you’ll analyze known anonymity and C2 networks and block them using pfSense’s DNS services. When you’re finished with this course, you’ll have the skills and knowledge to block and detect these techniques External Remove Services T1133, Exfiltration Over Alternative Protocol T1048, and Proxy: Multi-hop Proxy T1090.003 using pfSense.

Course Overview
Welcome to Pluralsight and this Blue Team Tools course featuring pfSense, the open source network analysis and detection tool developed by Scott Ullrich and Chris Buechler and maintained by Netgate. This tool can help us prevent and detect many different attacks and TTPs, just like its commercial counterparts. We'll use it in this course to help protect external remote services using a honeypot VPN. We'll use it for filtering ports used in file transfers to prevent exfiltration of data using alternate ports and protocols, and we'll also block traffic to known malicious networks through dynamic blacklists. PfSense is used as a network firewall and provides many other services, but its name was derived from the tool that the software uses, packet filtering, or pf; therefore, it's our packet filtering firewall ready to help us mitigate some potential threats. I hope that you'll join me in learning about pfSense in the Network Analysis pfSense course, here at Pluralsight.
