Report Exploring Public Key Certificates

Visit 5 other sites that you normally frequent using “http” to get there, but this time use the “https” prefix instead. Complete the table in the worksheet as you go. If HTTPS is not supported, then a certificate will not be available to investigate. An answer of “Depends” should be given if the site only supports HTTPS sometimes. For example, some websites support HTTPS only when you want to actually buy something, such as hitting the “check out” button.

Case Study 3.1

Read “Can We Trust Big Data?” (see attached file)
Answer the questions

Please use this strategy when you analyze a case:

  1. Identify and write the main issues found discussed in the case (who, what, how, where and when (the critical facts in a case).
  2. List all indicators (including stated “problems”) that something is not as expected or as desired.
  3. Briefly analyze the issue with theories found in your textbook or other academic materials. Decide which ideas, models, and theories seem useful. Apply these conceptual tools to the situation. As new information is revealed, cycle back to sub steps a and b.
  4. Identify the areas that need improvement (use theories from your textbook)
    • Specify and prioritize the criteria used to choose action alternatives.
    • Discover or invent feasible action alternatives.
    • Examine the probable consequences of action alternatives.
    • Select a course of action.
    • Design and implementation plan/schedule.
    • Create a plan for assessing the action to be implemented.
  5. Conclusion (every paper should end with a strong conclusion or summary)

Digital/Computer Forensics

 A digital forensics professional must know basic IT skills, understand computer architecture and networking, and have analytical and investigative skills, as well as strong attention to detail. Why do think all of these skills are necessary? Please explain 

Research Paper: ERM Strategy & Discussion

1. **Research Paper**

Discusses strategy and how ERM can be integrated with an organization’s overall strategy. Prepare a research paper on some of the various issues, protocols, methods, frameworks you found and discuss how – if possible – organizations can use ERM as strategy. It is perfectly acceptable if you deem ERM cannot be used as strategy, just back up your claim with scholarly research and justifications.

 paper should meet these requirements: 

Be approximately to six pages in length, not including the required cover page and reference page.

Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.

Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. 

Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

2. **Discussion**

Do you think that ERM is necessary in the contemporary organization and why?

the time complexity of algorithms.

 

Researchers from the School of BioSciences have requested our help with one of their

experiments. They are performing behavioural experiments with zebrafish. At any one instance in

time there are a large number of zebrafish in the aquarium. For their particular experiment, the

biologist take a snapshot of the aquarium and then need to find the longest series of zebrafish such

the length of each fish along the horizontal direction in the aquarium is increasing. They also need

to know the number of zebra fish in this series.

For example, the snapshot of the aquarium resulted in fish lengths of [2, 5, 3, 7, 11, 1, 12, 4, 15, 14, 6, 16].

One possible longest series of increasing lengths in this case is [2, 3, 7, 11, 12, 14, 16] with 7 zebrafish.

We say one possible longest series of increasing lengths here because it is not necessarily unique.

For example, the length 14 in the output could be replaced with 15: [2, 3, 7, 11, 12, 15, 16] and also

be valid.

In this question you will consider algorithms for finding the longest series of increasing lengths

via the function LongestIncreasingLengths(A[0, · · · , n − 1]), as well as the size of this output

array.

(a) [1+2+1 = 4 Marks] Consider a recursive algorithm:

i [1 Mark]Write down a recurrence relation for the function LongestIncreasingLengths.

ii [2 Marks] Using this recurrence relation, write a recursive algorithm in pseudocode for

LongestIncreasingLengths that only calculates the array size of the longest series of

increasing lengths. You do not need to output the actual array containing the longest

series of increasing lengths in this part of the question. For the example above with input

A = [2, 5, 3, 7, 11, 1, 12, 4, 15, 14, 6, 16], the output should just be 7. The pseudocode should

be about 10 lines of code.

iii [1 Mark] What is the time complexity of this recursive algorithm? Justify your answer.

(b) [5+1+1 = 7 Marks]

i [5 Marks] Building on from your recursive algorithm in part (a), write down a dynamic

programming implementation in pseudocode for the function

LongestIncreasingLengths(A[0, · · · , n − 1]) to find the longest series of increasing

lengths. This should also output the size of the longest series of increasing lengths. The

pseudocode should be about 20 lines of code.

ii [1 Mark] Explain how the recurrence relation used for your dynamic programming imple-

mentation involves overlapping instances.

iii [1 Mark] What is the time complexity of your algorithm and how much auxiliary space

was required. Justify your answer.

(c) [1+2 = 3 Marks] The time complexity of the recursive algorithm for LongestIncreasingLengths

was exponential, while the dynamic programming algorithm lead to a polynomial

time complexity (note, you need to determine that polynomial above). Here we will investigate

an algorithm for the function LongestIncreasingLengths that has a time complexity of

O(n log n).

Consider building a set of arrays for the input array A[0, · · · , n − 1]. As we scan along A, we

will compare A[i] with the final element in each array in this set. This comparison will satisfy

the following conditions:

(1) If A[i] is smaller than the final element in each array, start a new array of size 1 with A[i].

(2) If A[i] is larger than the final element in each array, copy the longest array and append

A[i] to this new array.

(3) If A[i] is in between, find the array with the final element that is greater than A[i] and

replace that element with A[i].

i [1 Mark] Write down the set of arrays that satisfy these rules for the input array

A = [0, 8, 4, 12, 2, 10, 6, 14, 1, 9, 5, 13, 3, 11, 7, 15].

ii [2 Marks] Building from these conditions, explain how an algorithm for the function

LongestIncreasingLengths could run with time complexity O(n log n). You may make

use any algorithm introduced in the lectures to help you with your explanation. Note: you

do not have to write this algorithm in pseudocode. We are expecting that you write a short

paragraph or a short list of bullet points describing the important steps of the algorithm

to explain the time complexity.

Hint: what if you only consider the final elements of this set of arrays as a single array?
