I like how you explained the different ways networks can be vulnerable, especially the part about insecure technologies and weak documentation. I agree with you, those things are easy to overlook but can cause big problems. I also thought your explanation of access control was really clear. I think authentication and multifactor authentication are some of the best ways to make sure only the right people get into the network. Single sign on is helpful too because it keeps things simple for users while still staying secure. And the access control list is a smart way to block dangerous websites before they can cause harm. You broke it all down in a way that was easy to understand.
