Threat Modeling

A new medium-sized health care facility just opened and you are hired as the CIO. The CEO is somewhat technical and has tasked you with creating a threat model. The CEO needs to decide from 3 selected models but needs your recommendation. Review this week’s readings, conduct your own research, then choose a model to recommend with proper justifications. Items to include (at a minimum) are:

  • User authentication and credentials with third-party applications
  • 3 common security risks with ratings: low, medium or high
  • Justification of your threat model (why it was chosen over the other two: compare and contrast)

You will research several threat models as it applies to the health care industry, summarize three models and choose one as a recommendation to the CEO in a summary with a model using UML Diagrams (Do not copy and paste images from the Internet). In your research paper, be sure to discuss the security risks and assign a label of low, medium or high risks and the CEO will make the determination to accept the risks or mitigate them.

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 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. 

Information Governance wek-5-1

We learned that e-mail is a major area of focus for information governance (IG) efforts, and has become the most common business software application and the backbone of business communications today.  In addition, the authors provided details to support their position by providing 2013 survey results from 2,400 corporate e-mail users from a global perspective.  The results indicated that two-thirds of the respondents stated that e-mail was their favorite form of business communication which surpassed not only social media but also telephone and in-person contact. 

With this detail in mind, briefly state why the e-Mail has become a critical component for IG implementation? Support with references

Cloud Computing

 

Consider, in 500 words or more, how business processes as services can improve efficiency. This discussion is about business process as a service and security. 

Use at least three sources. Use the Research Databases available from the Danforth Library not Google.   Include at least 3 quotes from your sources enclosed in quotation marks and cited in-line by reference to your reference list.  Example: “words you copied” (citation) These quotes should be one full sentence not altered or paraphrased. Cite your sources using APA format. Use the quotes in your paragaphs.  Stand alone quotes will not count toward the 3 required quotes.

Movement of traditional IT Staff

 

The main focus is on the movement of traditional IT staff.  To facilitate cultural assimilation, IT and non-IT must become more integrated.  What are some strategies to implement to allow this type of interaction to occur?

Note: The first post should be made by Wednesday 11:59 p.m., EST.

Your response should be 250-300 words. 

Intro to Data Mining

You will need to ensure to use proper APA citations with any content that is not your own work.

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?

Assignment

 Discussion #1: Explain why it is useful to describe group work in terms of the time/place framework.
