Network Topology and penetration testing

Identify a network in which you are familiar. What topology is used? What, if any, penetration testing is done? What is considered best practice? In this paper, you should compare best practice of testing and topologies to the network you have identified and contrast the two. Your paper should be two pages in length with at least one reference in APA format (and accompanying citation) to back up your opinion. Remember do not just submit opinion – reference academic peer reviewed work.
