List and explain the new banking technologies and describe how fintech industries has transformed how banks operate

1. Research a cloud service model.
2. In a Word document, identify the following and write a brief summary of what you learned in your research.
   • What the service model is and what advantages it provides
   • What kinds of scenarios the service model is commonly used for
   • The management responsibility associated with the service model—what the provider manages vs. what you manage
   • A brief description of at least three different service providers for the cloud service model selected
3. Save your file, and submit it using the instructions below.

You have been given a task of reordering some data from a log file. Every line in the log file is a space delimited list of strings and all lines begin with an identifier that is alphanumeric.

Write a single Excel formula that runs a quick VLOOKUP, and generate the difference of Two position – Client Position, Vendor postion.

Keep in mind the identifier format between Vendor and client sheet are slightly different so you will have to compensate for it in your formula to get the identifiers to match-up. Other Excel lookup functions are acceptable as well as long as it gets the job done.

What did you learn about yourself this term?  What is your preferred style of leadership and how did it help you solve professional challenges? Be specific and provide at least three (3) examples. 

Role: Java Developer.

1.  Download and install MATLAB. Develop the following function using MATLAB

a.  Write a script that loads data from a file and display the first five instances. Create a matrix from the loaded instances. 

b.  Divide the loaded instances into two sets with one set containing 70% of the instances and the other containing 30% of the instances. Save each set into a variable. Name the variables ‘TrainingSet’ and TestingSet’. 

c.  Save the two new variable to a ‘.mat’ file. 

2.  Implementing Fisher LDA method using MATLAB. 

a.   Write functions that take the provided data set and compute the optimal projection vector following the fisher criterion. 

b.  The output from the main function must be the identified projection vector.

3.  Write functions to evaluate the LDA method using MATLAB.

a.  Write a script to perform cross-validation and report the average accuracy, standard deviation, sensitivity, and specificity. 

NOTE: There is no requirement to develop a GUI to visualize the intermediate or the results.

A report that includes the following items is due in addition to the source code for the functions:

–  A description of each function,

–  How to run the functions to get the reported results, and

–  The experimental results.

This week’s written activity is a three- part activity. You will respond to three separate prompts but prepare your paper as one research paper. Be sure to include at least one UC library source per prompt, in addition to your textbook (which means you’ll have at least 4 sources cited). 

Start your paper with an introductory paragraph.

Prompt 1 “Data Warehouse Architecture” (2-3 pages): Explain the major components of a data warehouse architecture, including the various forms of data transformations needed to prepare data for a data warehouse. Also, describe in your own words current key trends in data warehousing. 

Prompt 2 “Big Data” (2-3 pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology? 

Prompt 3 “Green Computing” (2-3 pages):  One of our topics in Chapter 13 surrounds IT Green Computing. The need for green computing is becoming more obvious considering the amount of power needed to drive our computers, servers, routers, switches, and data centers. Discuss ways in which organizations can make their data centers “green”. In your discussion, find an example of an organization that has already implemented IT green computing strategies successfully. Discuss that organization and share your link. You can find examples in the UC Library.

Conclude your paper with a detailed conclusion section. 

The paper needs to be approximately 7-10 pages long, including both a title page and a references page (for a total of 9-12 pages). Be sure to use proper APA formatting and citations to avoid plagiarism.

Your paper should meet the following requirements:

• Be approximately seven to ten 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, the course textbook, and at least three scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find supplemental 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.

• When should the architect begin the analysis?
• What are the activities the architect must execute?
• What is the set of knowledge domains applied to the analysis?
• What are the tips and tricks that make security architecture risk assessment easier?

Your nation’s technical staff expects you to report on all summit events once you return to your nation’s capital. The CISO has requested that each analyst work independently to create an Intelligence Debriefing for technical staff. This debriefing is a comprehensive report and is comprised of your BCP, SITREP 1, SITREP 2, and SITREP 3.

Each team member should develop his or her own briefing and submit independently. You may, however, use your team’s discussion area to share your findings with your peers.

M3A1: Case Study: Textbook Case 5.1 Yahoo

Wins the Gold Medal and Silver Medals for the

Worst Hacks in History!

This activity addresses the following module outcomes:

 MO1: Compare internal and external threats and the sources of data breaches.

(CO3)

 MO2: Compare the types of general controls. (CO4)

Case Study:

There seems to be a cybersecurity headline once a week about at least one company

or government agency being hacked or reporting some type of breach. In this module,

you have learned about the challenges associated with cybersecurity and ways the

threats can be mitigated. You will focus on the challenges experienced by Yahoo in this

case study.  

Write a 1.5 page paper not including the cover page or reference pages, that answers

the questions from the textbook case study 5.1 – Yahoo Wins the Gold Medal and Silver

Medals for the Worst Hacks in History!  You must cite at least five independent scholarly

sources to support your position, using appropriate APA format.

Before you begin writing, please review the Case Study Guidelines  download for

information.

Please take note of the resource listed below as you select external scholarly

sources for this assignment:  

 Excelsior College Library Homepage

 Library Overview [VIDEO]: A brief introduction to the EC Library (Links to an

external site.) [Video file, 03:53 mins]

 Starting Your Research Guide (Links to an external site.): It is highly

recommended you utilize the Excelsior College Library to conduct your research.

All students/researchers must be able to discern what is solid source/reference

material and what is not.

 What is scholarly (sometimes referred to as peer-reviewed) (Links to an external

site.)? [Video file, 04:00 mins]

Scholarly sources can generally be identified by several features:

 Content (topic being discussed)

 Audience (for the layperson or someone familiar with the research on the

subject?)

 Language (higher level language and discipline-specific terminology)

 Intent (case study, report of experimental results, etc.)

 Authorship (qualifications of author to write on the topic, usually an advanced

degree with years of experience and research on the topic)

 Peer-reviewed (material is evaluated by experts and only published if it meets the

discipline’s standards)

 References (other materials used in the research process are listed in a

bibliography or footnotes)

 Listing (Check Ulrich’s in the Research Databases to see if the publication is

listed as refereed.)
