What do you think would have prevented the incident?

Discussion on the physical security topic. In theory, everything may look straight forward to do some research and find an article where physical security has failed. It can be a server room breach, it can be a data center breach, and any scenario that physical security has failed would be your subject.
1. Find an article (from a reputable magazine or link) describing where physical security has failed.
2. Submit a review of this article. Propose a possible change in that organization’s physical security that could have prevented the breach/failure for that scenario. What do you think would have prevented the incident?
3. Submit at least 2 but no more than 3 pages double spaced, APA style MS Word document.
4. No photos or graphs.
5. Reference all sources used
