1.Examine Alexa’s skill in ordering drinks from Starbucks – they are?

2.Research Apple Home Pod. How does it interact with smart home devices?  Alexa is now connected to smart home devices such as thermostats and microwaves. Find examples of other appliances that are connected to Alexa.

Preamble

In August of 1997, a Swiss couple, John 52 years old and Buntham 26 years old Graben Stetter, were arrested at the Hilton in Buffalo, New York, and accused of smuggling thousands of computerized pictures of children having sex into the United States. The couple were alleged by authorities to have sold wholesale amounts of child pornography through the internet and carried with them thousands of electronic files of child pornography to the United States from their Swiss home.

Allegations

1. The couple were unproven to have agreed over the internet to sell child pornography to the United States (US) Customs agents posing as local US porn shop owners.
2. The couple were suspected to have agreed to sell 250 CD-ROMs to US investigators for $10,000. According to reports, one CD-ROM had over 7,000 images.
3. The couple were further alleged to have their 2-year-old daughter, traveling with them at the time of the arrest, who is also a victim.
4. Authorities professed that photographs of the 2-year old daughter are on the CD-ROMs the parent were distributing.

Mitigation

Criminal’s MO is a learned behavior that continue to grow, develop, and advance tirelessly as the perpetrators turn out to be more experienced, sophisticated, and confident in the operation. Digital imaging technology and the internet allegedly help to unearth Swiss couple; John and Bentham’s prevailing MO, with intent of producing, marketing, and distributing child pornography materials to counterparts, and vulnerable innocent citizens of the world community.

          Underground communications, seizure of 250 CD-ROMs and arrest of the Swiss couple was made possible by efficient use of computer and internet technologies. The couple were targeting international buying communities, secured agreement to sell and distribute illicit materials. Furthermore, the illicit items were alleged to have been digitized for transport, ease of storage, and ease of duplication as soon as the couple arrive in the United States. Emergence of computer and internet technologies helped digital forensic investigation in process.

Questions

The Swiss couple attempted to underestimate the United States custom agents and digital forensic investigator. Provide all-inclusive description on the importance of computer and the internet technologies.

The couple were suspected to have agreed to sell 250 CD-ROMs to US investigators for $10,000. Provide comprehensive narrative on how to approach the Swiss couple with only allegation; yet, not officially charged.

1)  Discussion #1: Explain the relationship among data mining, text mining, and sentiment analysis.

 
2)Discussion #2: In your own words, define text mining, and discuss its most popular applications. 

3)  What are the common challenges with which sentiment analysis deals? What are the most popular application areas for sentiment analysis? Why?

• How do data transmission errors affect your perception of each? In other words, does the possibility of error influence your decision regarding which would be better?
• What other factors would affect a company’s choice?

Assessment  002 R Analysis and Report (maximum 3000 words)

In this assignment you are going to simulate data from an area chosen by yourself. It can be cyber related, healthcare, industrial, financial/credit card fraud, commerce – anything. However, run your ideas past me first before diving in. If you recall from the dplyr tutorials we were able to simulate small amounts of data based on several dataframes. We then linked the data we required using join() commands, etc. We then obtained summaries of the data and could use ggplot2 to highlight trends, etc.  

1. Carefully, choose your domain. Give a rationale for simulating it.
2. Define your data frames, generate them using sample_n and/or other commands. There is a package called charlatan you may find useful for generating personal names and other values. About 4-5 dataframes will suffice.
3. Think about seeding trends and patterns in your simulated data that you can “detect” later.
4. Use dplyr to extract the columns you need from the dataframes.
5. Use some sort of analysis such as summaries to get statistics on your data. Break it down by a category variable such as e.g. time, gender, fraudulent V normal, etc.
6. In the write-up, I will expect to see an introduction section, methods, and then sections for Simulation of data and transforming data, Analysis of data; marks for plots should of course be in the Analysis section.

Part 1: Analysis of the Data (70 marks)

You will need to develop R code to support your analysis, use dplyr where possible to get the numeric answers. Regarding ggplot2, be careful as to what type of plot you use and how you use them as you have many records and want the charts to be readable. You should place the R code in an appendix at back of the report (it will not add to word count).  Section each piece of code with # comments and screenshots of outputs.

• Simulation of data (20 marks)
• Transforming data (10 marks)
• Analysis of data and plots (20 marks)
• Write-up of the data analysis (similar format of my R tutorials) (20 marks)

Part 2: Scale-up Report (30 marks)

The second part will involve writing a report. Now assuming your Part 1 was an initial study for your organisation, what are the issues when you scale it up and start using it in practice?

• Discussion of Cyber security, big data issues, and GDPR issues (20 marks)
• Structure of report, neatness, references. Applies to both Part 1 and Part 2 (10 marks)

Penalties: Do not go over word limit of 3,000 (other than ±10%) as loss of marks will occur according to the university guidance on penalties.

Output: Submit PDF electronic copy to Canvas before the deadline, along with a file containing your R code. The data should be generated from the R code, so do not submit any data.

I was wondering if you get help me running this program.

 Prepare answers according to the questions given in this week’s homework document.  The assignment is that you “provide a remediation plan based on the HackerView vulnerability assessment”  I have attached a sample assignment as a guide and a pdf that need to be followed. 

I have to submit this assignment on 11/5 2020 at 11:00 pm EST

Networks have changed drastically over the last 30 years.  With the first introduction of the 56k modem, which was about 3 typewriter pages per second, to speeds well over 1Gbps these days, the ability to use networks globally, has changed the way we do business.  Using research, determine where networks will go in the next 5-10 years and how that might impact the global economy.

According to Kirk (2016), The essence of “Formulating Your Brief” is to “identify the context in which your work will be undertaken and then define its aims: it is the who, what, where, when and how.” It could be formal or informal as any project you think you must make it. This phase is where you create a vision for your work.

1. Why is it so important to formulate your brief for a data presentation? Discuss some ways you would implement to formulate an effective brief. What are some advantages to your methods? What are some disadvantages?

2. Please provide a summary as to whether you agree/disagree with their advantages/disadvantages.

– apa

– 2pages

– no plagiarism

– 2 references

In 500 words or more, compare DNS failover and cloud failover. 

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.

Copying without attribution or the use of spinbot or other word substitution software will result in a grade of 0. 

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

Do not use attachments as a submission. 

Reply to two classmates’ posting in a paragraph of at least five sentences by asking questions, reflecting on your own experience, challenging assumptions, pointing out something new you learned, offering suggestions. These peer responses are not ‘attaboys’.   You should make your initial post by Thursday evening so your classmates have an opportunity to respond before Sunday.at midnight when all three posts are due. 

It is important that you use your own words, that you cite your sources, that you comply with the instructions regarding length of your post and that you reply to two classmates in a substantive way (not ‘nice post’ or the like).  Your goal is to help your colleagues write better. Do not use spinbot or other word replacement software. It usually results in nonsense and is not a good way to learn anything. . I will not spend a lot of my time trying to decipher nonsense. Proof read your work or have it edited. Find something interesting and/or relevant to your work to write about.  Please do not submit attachments unless requested.
