You did a great job outlining the various ways networks can be vulnerable and how access control measures can help protect them. I really liked how you explained the differences between multifactor authentication and single sign-on, as both have their own advantages depending on the situation. All of the control lists were also strong points; they’re often overlooked but can significantly boost network security by limiting exposure to risky sites. Overall, your summary clearly covers the key concepts and shows why layered security is so important.
