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.
