During the course, we use a lot of different tools (software) that are very specific to the cyber security field. These tools include: Burp Suite, which is like a Swiss army knife for security specialists, Wireshark to analyze what is happening inside networks, John the Ripper to audit the security of passwords, sqlmapfor automated SQL injection testing, SSH, FTP, scripting languages, like Python and Bash, and much, much more.Instead of installing all these tools on your computer directly, we will use a virtual machine that runs Kali Linux, a Linux distribution made specifically for cyber security specialists with a ton of tools pre-installed and preconfigured. These virtual machines (VMs) are fully working computers that run as software on a host computer. We will prepare your computer to be a host computer by installing virtualization software on it.To run a VM, you need virtualization software. We will use VirtualBox for that. Start by installing VirtualBox for your computer from their download page Make sure that you download the version that is made for your operating system (Windows, OSX for Mac, Linux).Once installed, you can use VirtualBox to create virtual computers. While you could do that, and start from scratch, it is far easier to download a prepared virtual machine image that allows you to run a computer with the things you need pre-installed. Also, if (when!) you break anything, it is easy to roll back to a working version. All you need to do is create a new VM from the original image and you are good to go again.Download the Kali Linux Virtual Box image. If you are absolutely sure you need it, you should download the 32bit versioninstead, but chances are you need the first link, the 64bit version.Create a VirtualBox NetworkBefore you create a VM to run Kali Linux, you should create a network that allows you to connect your VM with your host computer and even other VMs on your computer.Start VirtualBox, go to the VirtualBox preferences, choose networks and hit the plus icon to create a new network. Check the screenshot below for the settings:virtualbox settingsRunning Kali Linux VirtualBox for the first timeThe first time you want to run Kali, you need to create a VM in VirtualBox. To do that, you can go to the File menu in VirtualBox, and choose “Import” to import the .ova file you downloaded. Alternatively, you can (probably) just doubleclick the downloaded file :)Once imported (this may take a while), you can start the VM from the imported image. Before you do that, make sure to go to it’s network settings and tell it to connect to the NatNetwork you created earlier.Congratulations! You can now hit “Start” and run Kali Linux for the first time! You may need to sign into it. The user/password is kali/kali.kali runningTry it out!Now that you have Kali running, you will want to try it out. So visit Hackthebox.eu and try out some of the tools that are available in Kali. The first challenge is to get in and create an account:)Note that all this is optional, so if you can’t make this work, we will look into it together during the first week of the course.
