.. _virtualbox: VirtualBox ========== In this section, we'll cover installing Security Onion on VirtualBox. You can download a copy of VirtualBox for Windows, Mac OS X, or Linux at https://www.virtualbox.org. Creating VM ----------- - Launch VirtualBox and click the ``New`` button. - Provide a name for the virtual machine (``Security Onion 2.4`` for example) and then select the ISO image. It should automatically set type to ``Linux`` and version to ``Oracle Linux 9.x``. Click the checkbox for ``Skip Unattended Installation`` and then click the ``Next`` button. - Specify RAM and Processors as needed per the :ref:`hardware` section and then click the ``Next`` button. - Specify virtual hard disk size as needed per the :ref:`hardware` section and then click the ``Next`` button. - Confirm options and then click the ``Finish`` button. - Virtualbox should have automatically enabled a network adapter attached to the NAT network. Depending on what kind of installation you are doing, you may want to keep that as NAT or change to something else. If you want an additional network interface for sniffing from a TAP or SPAN port, then click the ``Settings`` button, click ``Network``, and then go to ``Adapter 2``. Enable the adapter, configure the network it should attach to, and then you will most likely want to go to Advanced and set Promiscuous Mode to either ``Allow VMs`` or ``Allow All``. Click the ``OK`` button. - Click the ``Start`` button to start the VM. - Follow the installation steps for your desired installation type in the :ref:`installation` section.
