I was doing some research for my firewall project that I wrote about the other day and wanted to add some system monitoring. I figured that the server that I host signal-chief off of didn’t currently have any monitoring going so I would use that (cause why test in the lab when you can test in production?). The system I decided to use was Tripwire which is an opensource project that is part of the Epel Linux repo. I put this together with help from a couple of different tutorials that I found online and combined.
Building a Firewall
This post is probably going to be updated a few times as it’s a work in progress as I figure things out. As I’ve noted before a few times, I like to write things out as I figure them out so that I don’t have to research time and again. Today’s project, replacing a pfSense firewall with a Centos server and Firewalld.
