I agree with your points, Hannah. Network vulnerabilities can come from many directions, and strong access control plays a major role in minimizing risk. Authentication is especially important because it ensures that users are verified before gaining entry to network resources. Multifactor authentication strengthens this process by requiring more than one form of proof, making it much harder for unauthorized users to break in.
Single sign-on can make access easier for users, but it must be properly secured so that one compromised login doesn’t give attackers access to multiple systems. You also make a strong point about access control lists. ACLs not only block harmful websites, but they also help enforce security policies across the organization by limiting users’ access to only what they need.
