Due Week 4 and worth 100 points

Suppose you are a security director for a consulting firm that implements, secures, investigates, and supports point-of-sale (POS) for small and medium businesses (SMBs) in the retail industry.

Read the article titled, “If you shopped at these 16 stores in the last year, your data might have been stolen” located at https://www.businessinsider.com/data-breaches-2018-4 Choose 2 stores from the list and research the specific attack or breach.

Write a paper in which you:

1. Summarize the attacks, providing details on the effects of the breach. 
2. Identify the common purpose of attacks on point-of-sale (POS) systems. 
3. Assess why and how these POS systems have become a prime target for hacking groups. 
4. Examine the forensics challenges that exist for investigations on POS systems.
5. Use at least two (2) quality resources in this assignment other than the article linked above. Note: Wikipedia and similar websites do not qualify as quality resources. 

Your assignment must follow these formatting requirements:

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. 

I need python code which can do the following,
Convert nested or complex JSON file to CSV file with respect to a schema file( schema file contains the keys required to be kept inside )

Before converting the file, if the file is huge it needs to split into small files and there should not be any memory exceptions while processing the huge file while converting to csv from json.

Once the files are split, then each file needs to be processed in parallel using multiprocess.

As an IT manager, discuss how other departments in your company could use the data visualization and other information display techniques discussed in this chapter.  Please list at least four examples.

Your main discussion should be 300 words or more. Please use your own words. Do not copy-and-paste.

Work through Module 2: Lab Activity (see the attachment) and submit the deliverables listed in the document.

Suppose you needed to replace  22 physical servers that are at end of life.  You were trying to convince your boss that a cloud strategy is the best approach to replace the servers.  Your boss is interested in your idea; however, he or she asked you to submit a business case.   

To prepare for writing the business case, use this forum to discuss the following:

1. What is cloud computing?

2. What cloud computing terminology and concepts do one need to know to write the business case, why?    

Five short answer questions related to hash table and hashing.

The questions are in the file, and I also uploaded the book.
