Our next project will be to setup a VirtualBox Lab where we will be an outsider performing a penetration test on a Windows Enterprise. We will setup up an environment to monitor traffic, like what our Security Operations Center or Network Operations and watch the attacks. We will then break into a Windows Server in multiple ways, and finally escalate to complete network take over.
This will be a very long lab, but a immense amount of learning will take place. I suggest that you use Clockify to log hours to get an idea of times needed for each task. This data will help build your prices out.
