3B: Threats to Validity

In research, the threat of internal and external validity is commonly discussed. However, some researchers view one more important than the other. In your writing, compare and contrast internal and external validity, and make a determination based on your research/reading for which of the two validity factors is most critical and why, using citations and references to validate your argument.

You work as an administrative assistant for the President of Bass University which employs around 300 faculty and staff.Your immediate supervisor, the President, has just informed you …

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

References: At least three peer-reviewed, scholarly journal references.

1. How do you describe the concepts of validity and reliability? 
2. From what view did you use in providing that description?

1. Calculate the timing of password-guessing attacks:

(a) If passwords are three uppercase alphabetic characters long, how much time would it take to determine a particular password, assuming that testing an individual password requires 5 seconds? How much time if testing requires 0.001 seconds?

(b) Argue for a particular amount of time as the starting point for “secure.” That is, suppose an attacker plans to use a brute-force attack to determine a password. For what value of x (the total amount of time to try as many passwords as necessary) would the attacker find this attack prohibitively long?

(c) If the cutoff between “insecure” and “secure” were x amount of time, how long would a secure password have to be? State and justify your assumptions regarding the character set from which the password is selected and the amount of time required to test a single password.

  2. Describe each of the following four kinds of access control mechanisms in terms of (a) ease of determining authorized access during execution, (b) ease of adding access for a new subject, (c) ease of deleting access by a subject, and (d) ease of creating a new object to which all subjects by default have access.

• per-subject access control list (that is, one list for each subject tells all the objects to which that subject has access)

• per-object access control list (that is, one list for each object tells all the subjects who have access to that object)

• access control matrix

• capability

3. Design a protocol by which two mutually suspicious parties can authenticate each other. Your protocol should be usable the first time these parties try to authenticate each other.

4. List three reasons people might be reluctant to use biometrics for authentication. Can you think of ways to counter those objections?

  5. If you forget your password for a website and you click [Forgot my password], sometimes the company sends you a new password by email but sometimes it sends you your old password by email. Compare these two cases in terms of vulnerability of the website owner.

  6. Defeating authentication follows the method–opportunity–motive paradigm described in Chapter 1. Discuss how these three factors apply to an attack on authentication.

  7. Suggest a source of some very long unpredictable numbers. Your source must be something that both the sender and receiver can readily access but that is not obvious to outsiders and not transmitted directly from sender to receiver.

  8. Humans are said to be the weakest link in any security system. Give an example for each of the following:

(a) a situation in which human failure could lead to a compromise of encrypted data

(b) a situation in which human failure could lead to a compromise of identification and authentication

(c) a situation in which human failure could lead to a compromise of access control.

 9. Explain why hash collisions occur. That is, why must there always be two different plaintexts that have the same hash value? 

10. What property of a hash function means that collisions are not a security problem? That is, why can an attacker not capitalize on collisions and change the underlying plaintext to another form whose value collides with the hash value of the original plaintext?

EXAM REQUIREMENTS

• Submit your answers as a single Word or PDF file, called “ISM 6316 Mid Term – ”.

• Follow APA Style (double-spaced, 12-point font, 1-inch margins).

• This is an individual assignment. It is not a collaborative effort, not a team effort. You are not

allowed to discuss this exam with anyone, classmates or others. If you have any questions or

doubts, contact me by email.

• Submit your answers by the deadline. Each 24 hour period that you miss the deadline, it costs

10 points.

Question 1. (40 points; max 2 pages)

Transitioning an organization from running development projects with the Waterfall approach to

Agile/SCRUM is not an easy undertaking. Reflect on what you think are the biggest challenges that

have to be overcome and how you would approach this transition.

a. Describe four different challenges that organizations face when they want to transition to

SCRUM. For each challenge explain what the challenge is and why this is a critical challenge in

your opinion.

b. Describe for each challenge that you identified above what strategies you would use to

overcome the challenge.

Question 2. (30 points; max 2 pages)

SCRUM was originally intended as a project management approach for software development

projects. However, one may argue that SCRUM can be used as a generic project management

approach that can be applied in the context of any type of project, covering different focus areas

in a company (e.g. marketing, finance, or HR). Reflect on this position. To what extent do you

agree that SCRUM can be used as a generic project management approach? To what extent do you

disagree? Where lay the limits of the applicability of SCRUM to the management of complex

projects?

Question 3. (30 points; max 3 pages)

Visit: https://michaelochurch.wordpress.com/2015/06/06/why-agile-and-especially-scrum-are-terrible/

(A pdf of the blog will be available on CANVAS as well).

As you can tell, not everyone is convinced about the value of SCRUM. Critically reflect on the

opinions presented in the blog. (Please note that you do not have to read/consider the hundreds of

responses to this blog).

a. To what extent do you agree with the author’s point of view? On what issues do you disagree?

b. Based on your experience/understanding of SCRUM, what kinds of adjustments to SCRUM and its

practices or what other initiatives would you explore to address some of the issues that the

author raises?
