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…

How to use PGP

How to use PGP

Hello everyone, hope you are all having a good day today. Recently I’ve been playing around with encryption. Specifically PGP encryption. It’s a bit embarrassing for me to admit this but, while I understand symmetric encryption, when it comes to asymmetric encryption that is a bit foggy to me. I always seem to forget what the difference between public and private keys are. Which one do you send to people? I know that it’s the public key, but it doesn’t…

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…

NoScript For Firefox

NoScript For Firefox

Hello everyone,   This week I’d like to talk about the NoScript addon which is available for Mozilla Firefox. I’ve been using NoScript for a few weeks and while I find it annoying sometimes. I do find it really nice that I am able to block things like Google Analytics and other similar scripts like that. If I don’t want a script to run on my computer. I don’t run it. Scripts only run if I tell them to run….

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…

Password Security

Password Security

Hello Everyone,   Being that this is Cyber security mouth and I’ve recently been ramping up my cyber security measures to even higher levels. This week I’d like to talk about my favorite password manager: KeePass. The main thing that I like most about Keepass is that it does not use any of that cloud storage nonsense when it comes to storing your passwords. Yes I know that this means that you need to find a way to store and transfer…

VeraCrypt for Windows Encryption

VeraCrypt for Windows Encryption

Hello again everyone, I start this week’s post off with a question: How many of you have used or at least heard about TrueCrypt? Now TrueCrypt has long since become an abandoned project. But as is often the case with Open Source software, the long standing project was ported and continues to be supported under a new name. This new name you ask? VeraCrypt. VeraCrypt is a very secure filesystem encryption software that allows users to even do things like…

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)….

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…
