If you are interested in penetration testing and haven’t heard of Securitytube.net, or their paid site pentesteracademy.com they are both worth looking into. Securitytube.net is like Youtube for hacking videos and there is a lot of information on there. I’ve just started up on one of the paid courses and so far the quality seems great for the price.
It was hard to find time, but I finally knocked out the move from the shared host I was running on over to Amazon EC2. I had some concerns with how my previous host was handling passwords, so I wanted to move to something I have more control over. The site does appear to run much faster and the monthly costs aren’t any more. Now I can get back to generating more content.
Virtualization is a great tool for security professionals, or anybody looking to learn more about security or IT. For little to no cost you can setup a number of servers/systems to learn new operating systems, test out servers before you put them into production or practice your pentesting skills in a safe environment. This is going to be a quick run down for people who don’t know much about virtualization.
What is virtualization? Computer virtualization is the process of taking a physical system and logically breaking it up, so that it can be used by multiple virtual systems. This is typically done in two different ways. One way to use virtualization is by installing a piece of software such as VirtualBox or VMware Workstation on top of an existing operating system. Microsoft even provides built-in virtualization software (Hyper-V) in some versions of Windows, starting with Windows 8.1. Using any of these products allows you to create a fully functional computer/server on top of your existing operating system. The virtual machine can be turned off and on as you please, and even have its own IP address on your network.
Another method of virtualization is called bare-metal, where a virtualization software/Operating System (OS) is installed directly on the hardware to provide virtualization services. VMware ESXi, Microsoft Hyper-V and XenServer are examples of bare-metal virtualization platforms. What you create with virtualization software are Virtual Machines (VMs). Virtual machines behave just like independent computers/servers. Networking options vary by virtualization product, but for the most part you can either keep the virtual machine isolated, or have it run right on your existing networks.
Virtualization for Free The best thing about virtualization is that there are a lot of free options available, some of them are even business grade.
VirtualBox Sun has VirtualBox, which is an open source virtualization software available for Windows, Linux and Mac. It is a great free alternative to VMware Workstation. If you are just getting started with vitalization I recommend VirtualBox. It is free and runs on Windows, OSX and Linux.
Hyper-V If you are in love with Windows you should have your head checked, but you can use this guide from the Techrepublic.com to get started with Hyper-V on Windows 8 or newer Hyper-V.

XenServer is an open source bare-metal virtualization platform, but is better suited for a work environment or for more advanced users.
This has been a quick overview of what virtualization is and free software options for getting started with virtualization.
Right now I am working on getting out a Linux Crash Course page and a post on virtualization. Stay tuned.
More updates today. The site’s layout has been tweaked and more sections have been added. Check out the new content regarding Open Source Firewalls, which are worth looking into if you want a serious firewall and don’t have the cash for a big name vendor. A great option for the home or SMB network.
Today I started work on the Gadgets page with some information and useful links for the Raspberry Pi mini computer.
I’m starting to get the basic site layout finished up and will start generating content shortly.
This site is a work in-progress. The idea is to provide informational posts on security and tech related topics. I also plan to provide links and other information useful to anybody interested in security, open source and general tech.
