Question 1

Suppose that you are employed as a data mining consultant for an Internet search engine company. Describe how data mining can help the company by giving specific examples of how techniques, such as clustering, classification, association rule mining, and anomaly detection can be applied.

Question 2

Identify at least two advantages and two disadvantages of using color to visually represent information.

Question 3

Consider the XOR problem where there are four training points: (1, 1, −),(1, 0, +),(0, 1, +),(0, 0, −). Transform the data into the following feature space:

 Φ = (1, √ 2×1, √ 2×2, √ 2x1x2, x2 1, x2 2).

Find the maximum margin linear decision boundary in the transformed space.

Question 4

Consider the following set of candidate 3-itemsets: {1, 2, 3}, {1, 2, 6}, {1, 3, 4}, {2, 3, 4}, {2, 4, 5}, {3, 4, 6}, {4, 5, 6}

Construct a hash tree for the above candidate 3-itemsets. Assume the tree uses a hash function where all odd-numbered items are hashed to the left child of a node, while the even-numbered items are hashed to the right child. A candidate k-itemset is inserted into the tree by hashing on each successive item in the candidate and then following the appropriate branch of the tree according to the hash value. Once a leaf node is reached, the candidate is inserted based on one of the following conditions:

Condition 1: If the depth of the leaf node is equal to k (the root is assumed to be at depth 0), then the candidate is inserted regardless of the number of itemsets already stored at the node.

Condition 2: If the depth of the leaf node is less than k, then the candidate can be inserted as long as the number of itemsets stored at the node is less than maxsize. Assume maxsize = 2 for this question.

Condition 3: If the depth of the leaf node is less than k and the number of itemsets stored at the node is equal to maxsize, then the leaf node is converted into an internal node. New leaf nodes are created as children of the old leaf node. Candidate itemsets previously stored in the old leaf node are distributed to the children based on their hash values. The new candidate is also hashed to its appropriate leaf node.

How many leaf nodes are there in the candidate hash tree? How many internal nodes are there?

Consider a transaction that contains the following items: {1, 2, 3, 5, 6}. Using the hash tree constructed in part (a), which leaf nodes will be checked against the transaction? What are the candidate 3-itemsets contained in the transaction?

Question 5

Consider a group of documents that has been selected from a much larger set of diverse documents so that the selected documents are as dissimilar from one another as possible. If we consider documents that are not highly related (connected, similar) to one another as being anomalous, then all of the documents that we have selected might be classified as anomalies. Is it possible for a data set to consist only of anomalous objects or is this an abuse of the terminology?

Write an essay discussing sqlmap, an automated tool for sql injection and database takeover in 500 words or more. Why do we need an automated tool for sql injection? 

Do not copy without providing proper attribution. This paper will be evaluated through SafeAssign. 

Write in essay format not in outline, bulleted, numbered or other list format.  

Use the five paragraph format. Each paragraph must have at least five sentences. 

Include an interesting meaningful title.

Include at least one quote from each of 3 different articles. Use the Research Databases available from the Danforth Library, not Google.  Place the words you copied (do not alter or paraphrase the words) in quotation marks and cite in-line (as all work copied from another should be handled). The quotes should be one  full sentence (no more, no less) and should be incorporated in your discussion (they do not replace your discussion) to illustrate or emphasize your ideas. Each quote must be cited in-line and at the end.

Scenario

After the recent security breach, Always Fresh decided to form a computer security incident response team (CSIRT). As a security administrator, you have been assigned the responsibility of developing a CSIRT policy that addresses incident evidence collection and handling. The goal is to ensure all evidence collected during investigations is valid and admissible in court.

Consider the following questions for collecting and handling evidence:

1. What are the main concerns when collecting evidence?

2. What precautions are necessary to preserve evidence state?

3. How do you ensure evidence remains in its initial state?

4. What information and procedures are necessary to ensure evidence is admissible in court?

Tasks

Create a policy that ensures all evidence is collected and handled in a secure and efficient manner. Remember, you are writing a policy, not procedures. Focus on the high-level tasks, not the individual steps.

Address the following in your policy:

§ Description of information required for items of evidence

§ Documentation required in addition to item details (personnel, description of circumstances, and so on)

§ Description of measures required to preserve initial evidence integrity

§ Description of measures required to preserve ongoing evidence integrity

§ Controls necessary to maintain evidence integrity in storage

§ Documentation required to demonstrate evidence integrity

Required Resources

§ Internet access

§ Course textbook

Submission Requirements

§ Format: Microsoft Word (or compatible)

§ Font: Times New Roman, size 12, double-space

§ Citation Style: APA

§ Length: 2 to 4 pages

Discuss in 500 words or more federated architecture in cloud systems. Remember that this is a cloud class, not a database class. 

Use at least three sources. Include at least 3 quotes from your sources enclosed in quotation marks and cited in-line by reference to your reference list.   Cite your sources using APA format. Use the quotes in your paragraphs.  Stand-alone quotes will not count toward the 3 required quotes.

Write in essay format, not in bulleted, numbered, or other list formats. 

The COSO framework of internal controls is practiced within companies around the world. The objectives of the COSO framework are closely related to its five components. For this week’s activity, please discuss these five components of the COSO framework. Be sure to include each components’ impact on each of the COSO framework objectives. What do you feel an auditor would most be concerned with during an IT audit? Lastly, discuss suggestions for integrating COSO framework compliance into a company in which you are familiar. 

Your paper should meet the following requirements:

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

• Follow APA7 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. The UC Library is a great place to find resources.

• 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.

 Develop the introduction to Effective Strategies on the IoT Cybersecurity where you discuss the problem gap identified and how it supported by the literature. 

From your research, discuss whether or not your organization has ISO 27001 certification. Outside of overall protection from cyber-attacks, describe, in detail, some other benefits your organization will achieve in obtaining this certification. If your company does not have this certification, how can they go about obtaining it?

Present your discussion post as if you were presenting to senior leaders of your company.

Please make your initial post should have 500 words and the post will do at least TWO of the following:

• Explain, define, or analyze the topic in detail
• Share an applicable personal experience
• Provide an outside source (for example, an article from the UC Library) that applies to the topic, along with additional information about the topic or the source (please cite properly in APA)

At least one scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.

Find a process within an business that you feel can help that business gain a competitive advantage.

Create a word document that contains at least the following:

Start by introducing the project:
* Explain the process you will be reviewing and want to modify.
* Explain the business and industry where this process exists.
* Give an overview of the current process and how it works.

Based on the materials within this course, explain a new technology that should be deployed.
* Be very specific.  Note the exact technology as well as the specific application of that technology (i.e. technology might be Smart Automation – while the specific application might be light dimming technology).
* Identify the pros and cons of the new technology. 
* Identify how the new technology would impact the business/industry and the process that was selected to be modified.

What are the various factors the business should consider before deploying the new technology.
* Are their cost considerations. 
* What other project are impacted or might impact the deployment. 
* What are 5 to 10 things the business should consider before implementing and explain how important it would be to use the new technology (i.e. use some type of scale like ‘Critical’ vs ‘High Priority’ vs … vs ‘Good to have’).

The project must be at least 3 pages in length, double-spaced, 12-font.  This total length does not include the APA approved cover page and the reference page(s).  There must be at least 3 APA approved references, with citations, to support your work.
