Computer Science Homework Help

I’m working on a cyber security discussion question and need support to help me learn.

What are the best security controls for physical access security at a site, does it become harder to support in a campus setting (more than one building)?

Provide an example of a location, either school or business that you think is too secure and one that is not secure enough. Would it be difficult to secure equipment at a site that is not very secure?

How are the physical security controls align to the organization or business goals? Also, what role do administrative controls have in verifying the alignment of controls?
