Recently, there have been several cases of someone losing possession of their Twitter account in a

hacking attempt. Review the following two stories:

Develop an attack tree for stealing a Twitter handle that encompasses the basics of these attacks,

as well as other threat vectors you can think of. Your tree should include at least 25 nodes and be

comprehensive. For an explanation of attack trees, refer to the following article:

2 Evaluation Framework 

In this question you will develop your own evaluation framework (like the one from the lecture on

password alternatives) I ATTACHED . First choose a problem with a security aspect that has at least 4 competing

solutions (try to come up with your own topic, however a few suggestions are below). To compare

these solutions, come up with at least 3 security criteria and at least 3 non-security criteria (functionality,

usability, deployability) that would be desirable for the solution to hold (ideally, they will

conflict in such a way that no solutions will hold all of them). Determine a score for the evaluation

of each property. The example in Lecture 2 used three scores: the solution did not meet the criteria,

it almost held the property, and it fully held the property.

Explain each criteria, and exactly what must be true of the solution to get each possible score in your

ranking. Then evaluate each solution against each criteria, justifying your score. Summarize this in

a chart.

Refer to http://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-817.pdf for a more involved security

evaluation.

“International Opportunities” Please respond to the following:

Given  the advantages of international diversification, determine why some  firms choose to not expand internationally. Provide specific examples to  support your response. Use current readings and lecture material to  support your response. 
As firms attempt to  internationalize, they may be tempted to locate their facilities where  business regulation laws are relaxed. Discuss the advantages and  potential risks of such an approach, providing specific examples. Use  current readings and lecture material to support your response.
