Installation of PFELK on ubuntu. ELK for pfSense

As per my promise or I can say mention of pfSense installation I am presenting the installation guide. By the way, I just copied every step from the GitHub repository document if anyone is wondering. Steps given in the official documentation are perfect and straight forward. I honestly rewrote it because I was running out of ideas and I promised it in the previous post.  But one thing I would say that if you are a beginner like me don’t use scripted install, do it manually.

The one important thing I would say about ELK (btw, I have told this many times before but I need content, JK ;)) is that it is a base for so many SIEM and cannot be neglected from learning it from the base. You can customize it so much to basically make it look like you :). Now enough of these fillers let’s get straight … Read more
