As before, once it is downloaded you need to extract it. We installed the Kali Linux distribution to include the VMware tools. Many of the chapters end with a challenge to the reader that is designed to enhance and perfect their penetration testing skills. Welcome to Reddit, the front page of the internet. Click on File New Virtual Machine.
VMnet8 This is the most common switch we will use, because it allows us to share the physical network connection with the host while remaining at a private address shielded from the external network.
The biggest benefit of this is that we can access the Internet. This configuration is known as the Network Address Translation NAT ; as mentioned earlier, it is the most common switch that we will use.
When we expand our network to include the layers to represent an enterprise architecture, this is the switch that will connect us to the perimeter so that we can place a machine external to our architecture and emulate a true attack from the external segment.
An example of this switch is shown in the following image:.
A thing to note here is the fact that we can customize and configure port forwarding. This allows us to limit the ports that a machine can receive traffic to at the virtual switch level. We do this for both TCP and UDP ports, so effectively we can custom configure our environment to restrict port traffic just like what we can achieve with a firewall.
One of the ways we might use this is when we know we have a vulnerability on the application running on port , rather than test everything on the machine. We can restrict all of the traffic and only allow the traffic to the specific port that we want to test.
We can do all of this without taking the extra time to set up a firewall and then a rule to only allow traffic to our selected port. It is not something that is common, but it can allow us to standup a quick list of allowed ports to a target virtual machine and then test it. Folders The last thing we will discuss within the design is the concept of Folders.
This used to be referred to as Teams; however, in the latest versions of VMware Workstation, they are now known as Folders. While this technically is not the network design, it is important to explain the power that Folders provides us for our designs. We can use this to power on all of the machines at the same time, well, not actually at the same time; the tool uses a 10 second delay when powering the machines on. You can also power on a selected number of machines using the Ctrl key and click on the machine you want to power on.
Once you have selected the machines to power on, and pressed the play button, it is just a matter of time until they are powered on. An example of Folder with machines contained within is shown in the following image:. Understanding the default architecture With the default configuration of the VMware Workstation, we can create a multiple layer design.
If we counted the VMnet0 switch, then we could architect three segments, but, since we have discussed the downside of doing this, we will just use the first two switches to set the initial phase of the architecture for the book. As we continue, we will add additional switches until we have the final design of the network that we wish to achieve. Installing Kali Linux We have a number of choices when it comes to installing Kali, and the one we select is largely a personal preference; the preferred method as a tester is to install the machine from the iso image, because that will provide you with the most control over the configuration of the machine.
This method can also present challenges, but for the most part, it should not be too painful. Kali can be downloaded from http: The preferred option is to download the bit version iso image, as it allows you to take advantage of more available RAM.
Once you have downloaded and verified the image, you will mount the iso image in the VMware Workstation and this will allow us to boot it and complete the installation process as follows: Start the VMware Workstation on your host machine. Click on File New Virtual Machine. Accept the default settings and click on Next.
In the next window, select Installer disc image file iso. Browse for the iso image you downloaded and click on Next. Leave the default Linux, and click on the drop-down window, and select Debian7. Enter a name for the virtual machine as Kali Linux Attacker. You can change the location that it is saved to, but I recommend that you leave it at the default and click on Next. In the next window, change the Maximum disk size to This might seem like a large number, but it is better to do this now and not later.
We will not be allocating the space for this, so it is OK to set it at a high number. The other setting that is of interest is the storing of the virtual disk; we will leave this at the default.
Then, click on Next. Before you click on Finish, set up the hardware. Click on Customize Hardware. We want to customize the network cards and also set the RAM that we want for the virtual machine.
The more RAM you set, the better. This is something that is largely dependent on the amount of RAM you have available. If possible, dedicate a minimum of 2 GB to the machine. For our example, we are going to set 4 GB. Select the Host only radio button, then click on Finish. Close the configuration window by clicking on Close.
If there is an option to Power on this virtual machine after creation, clear the checkmark and click on Finish. This will open up the virtual machine in the VMware Workstation, and it will provide you with the opportunity to review your settings.
Once the settings have been reviewed, click on Power on this virtual machine. At this point, we created the virtual machine, configured the hardware, and defined the structure of the machine with respect to the network cards, the physical RAM, and the size of the hard drive. At this point, the machine is now ready. We just have to boot the machine and install the software the same as if it were a separate machine.
Another powerful benefit of virtualization. Perform the following steps: Click into the window and select the Graphical install.
On the next screen, select your language and then your location. Click on Continue. Select your keyboard and click on Continue.
This will start the install process. The install will detect the two network interfaces and properly select the eth0 interface. Leave it at the default and click on Continue. You will be prompted whether or not to continue without a default route; click on Yes and then click on Continue.
This is because we will let the VMware provide this information when the machine boots. Do this also for the name servers and the domain name. We are not installing the software on a physical machine, so we can bypass these steps. Accept the hostname or change it if you desire to use another name and click on Continue. The next thing you need to do is enter a password for the root user. Make sure you remember it and click on Continue. Configure the clock to match your time zone and click on Continue.
Since we are in a virtual environment, accept the default for the disk and click on Continue. Read all of the messages and click on Continue. Finish partitioning and write the changes to the disk. You will have to select Yes to complete the process.
Then, you will see the installation of the system taking place. When you are prompted for a network mirror, select No and then click on Continue. Select the hard disk, and then click on Continue. If all goes well, you should get the completion message. Once the machine boots, login with the username of root and the password you created during the installation. We now have a complete install of the Kali 2. At this time, we are ready to continue with the configuration of the machine, and the ever so important capability of installing the VMware tools.
Let's get started now!
We are now ready to update the software and then install VMware tools. Open a terminal window and enter: Once this has completed, it is time to install the VMware tools.
This can be a bit of a challenge, but it does make our lives much easier when working with virtual machines. At the time of this writing, the Kali Linux distribution used the 3. Attempt to install the Linux headers with the following command: If you get a message to the effect that the headers are not found, we can continue on to the next step.
If the headers are installed, then note the path in case the VMware tools installation does not find them. Once the tools have extracted, navigate to the folder, and enter: The installer will ask questions; accept all of the defaults until you get to the valid header path. If it does not find it, you can enter the one from earlier; alternatively, the best bet is to enter no. Accept the rest of the defaults, and the tools should complete the installation.
Reboot the system. Once it comes online, login and then click View Fit Guest Now. You should now have a larger screen, which means that the tool is installed correctly.
You now should have your Kali Linux machine installed and configured with the VMware tools. Creating the switches We know that we have three switches that were created when we carried out the installation. This will allow us to create a number of different architectures, but we still need more switches for our design. We want to customize the switches to meet the IP addresses that we will use throughout the book. We have four subnets that we use throughout the book, and we will configure them now.
This does not include the last chapter, and we will customize four switches just for that. This will bring up the network configuration window, and we want to configure the following: Name VMnet1. This will provide us with the four subnets for the book, and also the four subnets in the last chapter.
An example of the settings is shown in the following image:. We now have all of the switches that are required and can emulate any of the required network architectures throughout the book except for the load balancing requirement.
We will configure that later. Putting it all together We are now ready to build a number of the machines that we will use throughout the book. We will not completely configure the images until we are in that section of the book where they are required.
Go to http: Once the image has been downloaded, start VMware Workstation and click on File New Virtual Machine to start the creation of the new machine.
Accept the default and click on Next.
Select the radio button for I will install the operating system later, and then click on Next. An example is shown in the following image:. The installer will next ask for the version to install. We will leave the default Guest operating system setting, select the version as Ubuntu bit, and click on Next.
Accept the default sizes and click on Next. The machine is now ready to go; click on Finish. Since we elected to not install the OS with easy install, we need to connect the DVD to the iso image. Then, click on OK.
Once you have verified your settings, click on Power on this virtual machine. Enter the following settings for the installation: What is your name: What name do you want to use to log in: Choose a password: What is the name of this computer?: Require my password to login: After the installation has completed, the system will reboot.
Login to the machine. On the left side of the desktop, the top most icon is the software launcher; right-click on it and select Applications:. In the search window, enter terminal and open the terminal window that comes up from your search:. In the terminal window, enter the following: After the system has updated, we are now ready to install the services we need for the labs. Enter the following command: You will have to enter a password for the MySQL user.
For simplicity, enter the same password as you did for the user on the machine. Installing Kioptrix The next machine we need to install is the Kioptrix machine by Steven McElrea aka loneferret and Richard Dinelle aka haken29a of the http: Choose your language of choice and click on the KioptrixVM Level 1 link and download it. You will notice that there is another VM that has been added to the choices; but for our purposes, we will continue with the same VM from the first edition.
Once the download has completed, extract it. We only need to open the virtual machine. Once it has been extracted, click on File Open, navigate to where the machine has been extracted, and open it. Once the machine is open, we need to make some configuration changes. Click on Edit virtual machine settings Memory and change it to The following image shows the settings for the machine:.
Using the same techniques as before, download and create the machine for Kioptrix Level 3, located at the Kioptrix VM Level 1. The following image shows this:.
As before, once it is downloaded you need to extract it. Once the machine is extracted, use the same concepts as before and configure the machine with the same networking settings. Leave the rest at the default. Creating pfSense VM As discussed in the first edition, the pfSense firewall is much more than just a firewall, and it is easy to install and configure.
This suits our purposes here in our testing environment. Wiki contains all the links in one place! Feel free to post in the threads, or message the mods to add more to the lists!
