Ultimate Build 2019 – pfSense

Ultimate Build 2019 – pfSense

Sometimes it is fun to take a short break from the (somewhat) sensible world we live in and do something that is truly crazy and having a bit of fun the process. Today I really turned it up a few notches and decided to design, price out, and analyse a truly insane pfSense firewall build!

Wireshark for Firewall Rules

Wireshark for Firewall Rules

I found this interesting article here where I learned that it is possible to automatically generate ACLs rules for many common firewalls including (but not limited to). Linux IPtables, Windows Firewall, Cisco IOS, packet filter (I don’t know if this extends to pfSense but I would imagine so since the PF package is what pfSense was originally based on), and more. This can be very useful weather you are trying to allow something or block it. Wireshark has an option…

My New Discovery in The Suricata pfSense Package

My New Discovery in The Suricata pfSense Package

Hello Everyone, This week I would like to talk about something that has concerned me for quite some time now. As many of you know I have experience with Suricata and the Suricata package for pfSense. As I’ve progressed throughout my cybersecurity class I’ve noticed that they seem to suggest running an IPS on the internal network as well on on the WAN side. Now I’ve been running Suricata on my internal network for a  long time now. However, I was…

Surricatta Logs on pfSense

Surricatta Logs on pfSense

Hello Again everyone, Today I’d like to talk about network logs packet analysis and how truly expensive it can be. First off, I want to make it clear that I am not in any way recommending that you don’t log packets. Logging packets is an essential part of network security and I would argue that it is pretty much impossibe to ensure that your network is secure without doing some form of packet logging (at least in the short term)….

Is My OpenVPN Traffic Being Decrypted?

Is My OpenVPN Traffic Being Decrypted?

Hello everyone,   As per my previous post about OpenVPN on pfSense I would like to tell you all a problem that I’ve been having recently since I’ve started trying to use it to protect myself on my school’s public WiFi network. You see, I like all college students have a smart phone and I can create my own private wireless hotspot with it. To which I connect my laptop to it while I’m in class so I don’t have…

pfSense can Protect You Even on the Go

pfSense can Protect You Even on the Go

Hello everyone,   Once again I would like to talk about using pfSense to setup an OpenVPN server which you can use to protect yourself on open and public WiFi networks. You see the problem that I often encounter while on the go is that there are no WiFi networks that I trust. I barely trust my own home WiFi network and I set it up to be very secure and I monitor it constantly! We are told never to…

Today I would like to introduce you all to a very useful package that you can install on pfSense: ntopng. Formally known as ntop, ntopng allows you to Analyze the different traffic on each  interface on your pfSense box. This can be extremely valuable from a security perspective because not only can you see what is happening on your network. You can quite easily get an idea of what exactly your systems are doing. As well as get a sense…

pfSense for Learning Computer Networking & Cybersecurity

pfSense for Learning Computer Networking & Cybersecurity

Hello everyone!   This week I want to continue talking about pfSense and why I think it is one of the best pieces of software especially for anyone who is looking into (or is already in) a career network administration or cybersecurity. I recently started taking a cybersecurity class and as part of our first lesson we reviewed the basics of how computer networks work and that got me thinking about pfSense and the journey that I’ve taken on my…

ECC RAM Not Working in my (Surprisingly) ECC-capable Motherboard?

ECC RAM Not Working in my (Surprisingly) ECC-capable Motherboard?

Hello everyone, A couple of days ago I treated myself to a new stick of RAM for my PFsense box. I was going from 4 GB non-ECC memory to a single stick 16GB ECC stick.  Normally wouldn’t bother going with ECC but the ECC stick was actually cheaper then the comparable non-ECC stick. The RAM was branded HP (although the picture shows that it’s Lenovo banded). However I figured RAM is RAM and assumed this wouldn’t be an issue. When…

One day while I was looking though the options I noticed an option to use a GPS. Curious what this was about I Googled it and I found this video from  Mark Furneaux who is a YouTuber who’s opinion I strongly respect.     I personally have shortly considered doing…

How to Block YouTube Mobile App with PFsense

How to Block YouTube Mobile App with PFsense

I’ve been watching a lot of YouTube videos on my phone. I often do this before I fall asleep at night and is the first thing I do when I wake up in the morning. The amount of time that I spend watching videos isn’t an issue when I’m falling asleep. However, when waking up in the morning I will sometimes watch YouTube for several hours before finally getting up and starting my day. Now, I could show some backbone…
