Splunk + Minecraft?

Splunk + Minecraft?

Hello everyone! Today I’ve been spending a lot of time working in my home lab (as I so often do). And I’m pleased to report that I have learned many new things about the rsyslog package available (and often preinstalled) on most in Linux distributions. What is rsyslog? rsyslog can send it’s logs over to virtually any type of syslog server on the market. Including more advanced systems such as Splunk and other SIEM products. That doesn’t come as a…

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…

Using Syslog

Using Syslog

Happy Thanksgiving everyone! This week I’ve been hearing quite a bit about Syslog and how much of a help it is when you’ve got multiple servers that need to be constantly monitored. Enter the long standing solution, syslog. Syslog has been around forever and like a lot of network administrators when I first learned about Syslog I didn’t have a need for it. I had so few computers back then that I didn’t see the need. Like so many I…

Blockchain in the Election System

Blockchain in the Election System

Hello everyone,   With election day finally here many people are heading out to go vote (and if you haven’t voted yet I encourage you to do so). Many people are concerned about election interference and weather or not you consider this to be a real threat (I’m not going to take sides). There have been a few proposals on what to do about this. But one of the most publicized ideas is to use Blockchain. You may remember hearing…

OSSIM SEIM Systems

OSSIM SEIM Systems

This week I’ve been doing a lot of research on SEIM systems both as part of the classes that I’m taking and out of my own curiosity. SEIM sounds like a very powerful and useful tool which I have yet to really play with.   Enter AlienVault’s OSSIM, and all of it’s open-source awesomeness. There is a lot of reasons for why an organization (like Aeatacraft) might consider running it because it is a very capable and you can beat…

Ethical Hacking and the US Power Grid

Ethical Hacking and the US Power Grid

This morning I did what many early-20-year-old-men do: I watched YouTube videos on my phone before getting out of bed this morning. However, unlike many early-20-year-old-men I watch a lot of educational programming as well (although I have been known to watch the occasional stupid video from time to time). This morning I noticed a video that caught my eye: Watch hackers break into the US power grid at first I was skeptical, I figured that it couldn’t possibly be…

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)….

All About OpenVAS

All About OpenVAS

Hello again everyone, Now you may not like the idea of using vulnerability scanners or other hack tools. However, OpenVAS is VERY powerful tool to anyone who is running nearly any type of server and wants to make sure that it is protected. Now you might be thinking that as long as you keep your machines up-to-date you should be fine. But that is not entirely true. While updates are an important part of protecting your systems misconfiguration is another…

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…
