Visible and invisible physical security controls.

 
 
 
 
 
Many business environments have both visible and invisible physical security controls. You see them at the post office, at the corner store, and in certain areas of your own computing environment. They are so pervasive that some people choose where they live based on their presence, as in gated access communities or secure apartment complexes. Alison is a security analyst for a major technology corporation that specializes in data management. This company includes an in house security staff (guards, administrators, and so on) that is capable of handling physical security breaches. Brad experienced an intrusion—into his personal vehicle in the company parking lot. He asks Alison whether she observed or recorded anyone breaking into and entering his vehicle, but this is a personal item and not a company possession, and she has no control or regulation over damage to employee assets. This is understandably unnerving for Brad, but he understands that she’s protecting the business and not his belongings.
When or where would you think it would be necessary to implement security measures for both?

Threat Modeling

 
 
 
A new medium-sized health care facility just opened and you are hired as the CIO. The CEO is somewhat technical and has tasked you with creating a threat model. The CEO needs to decide from 3 selected models but needs your recommendation. conduct your own research, then choose a model to recommend with proper justifications. Items to include (at a minimum) are:
User authentication and credentials with third-party applications
3 common security risks with ratings: low, medium or high
Justification of your threat model (why it was chosen over the other two: compare and contrast)
You will research several threat models as it applies to the health care industry, summarize three models and choose one as a recommendation to the CEO in a summary with a model using UML Diagrams (Do not copy and paste images from the Internet). In your research paper, be sure to discuss the security risks and assign a label of low, medium or high risks and the CEO will make the determination to accept the risks or mitigate them.
