As we have mentioned earlier, the goal of building our pen testing ranges is to practice our skills. Therefore, we need to approach the architecture that we created and attack it at every location and entry point. Furthermore, it is very important that we practice attacking the targets directly, that is, on a flat network. Once we have attacked and identified the reactions of the targets from the different types of attacks, we change the approach and attack through the layered architecture to see what the reactions are and make a comparison of the results from the different locations.
