I set up intrusion detection and intrusion prevention on my network using OPNsense, here's how

The internet is a scary place, and since building my own OPNsense router where I can see all of the traffic in and out, I've never been more convinced of that. I had already set up OPNsense with the goal of configuring Intrusion Detection Systems and Intrusion Prevention Systems (IDS and IPS, respectively). I moved as quickly as I could to deploy them when I saw the constant traffic that was scanning my network, looking for open services. I've since set up a honeypot to capture some data, but that's a story for another day.
