Usuability testing

#1: What are the main reasons for the recent popularity of data mining? 

 #2: Discuss what an organization should consider before making a decision to purchase data mining software. 

#3:  What are the privacy issues with data mining? Do you think they are substantiated? 

 When submitting work, be sure to include an APA cover page and include at least two APA formatted references (and APA in-text citations) to support the work this week. 

• Distinguish between due care and due diligence.
• Based on your experience, provide examples of due care and due diligence.

Select any example of a visualisation or infographic, maybe your own work or that of others. The task is to undertake a deep, detailed ‘forensic’ like assessment of the design choices made across each of the five layers of the chosen visualisation’s anatomy. In each case your assessment is only concerned with one design layer at a time.

For this task, take a close look at the data representation choices:

1. Start by identifying all the charts and their types
2. How suitable do you think the chart type choice(s) are to display the data? If they are not, what do you think they should have been?
3. Are the marks and, especially, the attributes appropriately assigned and accurately portrayed?
4. Go through the set of ‘Influencing factors’ from the latter section of the book’s chapter to help shape your assessment and to possibly inform how you might tackle this design layer differently
5. Are there any data values/statistics presented in table/raw form that maybe could have benefited from a more visual representation?

Assignment Requirements: At least 500 words in length

complete a case study of the organization you work for (use a hypothetical or “other” organization if more applicable) that will address the following prompts:

• Describe the organization’s environment, and evaluate its preparedness for virtualization.
• Explain Microsoft (or another product) licensing for virtualized environments.
• Recommend a configuration for shared storage; make sure to discuss the need for high availability and redundancy for virtualization for the organization.

• Make a recommendation for cloud computer use in the organization, including a justification for your recommendations.

Submit your research paper as a single document. Your paper should meet the following requirements:

• Be approximately 2-4 pages in length, not including the required cover page and reference page.

1. Distinguish between vulnerability, threat, and control.

2. Theft usually results in some kind of harm. For example, if someone steals your car, you may suffer financial loss, inconvenience (by losing your mode of transportation), and emotional upset (because of invasion of your personal property and space). List three kinds of harm a company might experience from theft of computer equipment.

3. List at least three kinds of harm a company could experience from electronic espionage or unauthorized viewing of confidential company materials.

4. List at least three kinds of damage a company could suffer when the integrity of a program or company data is compromised.

5. List at least three kinds of harm a company could encounter from loss of service, that is, failure of availability. List the product or capability to which access is lost, and explain how this loss hurts the company.

6. Describe a situation in which you have experienced harm as a consequence of a failure of computer security. Was the failure malicious or not? Did the attack target you specifically or was it general and you were the unfortunate victim?

7. Describe two examples of vulnerabilities in automobiles for which auto manufacturers have instituted controls. Tell why you think these controls are effective, somewhat effective, or ineffective.

8. One control against accidental software deletion is to save all old versions of a program. Of course, this control is prohibitively expensive in terms of cost of storage. Suggest a less costly control against accidental software deletion. Is your control effective against all possible causes of software deletion? If not, what threats does it not cover?

9. On your personal computer, who can install programs? Who can change operating system data? Who can replace portions of the operating system? Can any of these actions be performed remotely?

10. Suppose a program to print paychecks secretly leaks a list of names of employees earning more than a certain amount each month. What controls could be instituted to limit the vulnerability of this leakage?

Answer the following the question:

We live in a world of data, perhaps too much data. Organizations continue to store data indefinitely. In fact, about 90% of the data stored on todays databases is deemed worthless within 3 months. Think about your email. How often do you ever go back to an email from six months ago. But you still keep it for what? How should organizations government personal data in a data warehouse? What are some best practices you might suggest to your organization if you were the CIO to ensure that the data in the system was maintained properly?
