Check the slides “OS Security II,” pg. 4-8. You are to implement a Dictionary Attack with and without Password Salt program in Python.

If you are not familiar with measuring execution time in Python, see the following website:

https://stackoverflow.com/questions/1557571/how-do-i-get-time-of-a-python-programs-execution

See the following steps.

1. Accept a user password of length N as keyboard input to your program. You can determine your own length N.

2. Compute the hash of the password from step 1.

Your hash function H() is simply the checksum. (See Assignment 2)

3. Now you become an attacker and try to find the password of length N.

Try every combination of length N password and for each combination, compute the hash and compare to the hash of the password from step 2.

Measure execution time.

4. Now let’s reinforce our password using the password salt. Accept an arbitrary non-negative integer number as keyboard input to your program.

5. Compute the hash of the concatenated password salt and password from step 4 and step 1. To compute the password salt portion of the checksum, you can treat the entire password salt as EITHER a single integer OR multiple one-byte integers.

6. Now you become an attacker and try to find the concatenated password salt and password.

Try every combination of an arbitrary non-negative integer number and length N password and for each combination, compute the hash and compare to the hash from step 5.

Measure execution time.

NOTE: your program should have separate functions for the checksum and the two dictionary attacks with and without the password salt by the attacker.

instructions:

1. Open the EX2019-ChallengeYourself-4-3 start file. The file will be renamed automatically to include your name. Change the project file name if directed to do so by your instructor, and save it.
2. If the workbook opens in Protected View, click the Enable Editing button in the Message Bar at the top of the workbook so you can modify the workbook. 
3. Change the name of Sheet1 to: NewHybrid
4. Apply the Retrospect theme.
5. Change the NewHybrid sheet tab color to Orange, Accent 1 (the fifth color from the left in the top row of theme colors). 
6. Add header and footer information to the NewHybrid worksheet. 
   1. Set the center header section to display the sheet name. 
   2. Add the page number to the left footer section.
   3. Set the right footer section to display the current date. 
7. Freeze panes so rows 1:8 and columns A:B remain in place when you scroll through the worksheets. 
8. Make a copy of the NewHybrid sheet, placing before the Working worksheet.
9. Change the name of the new sheet to: Option2
10. Change the Option2 sheet tab color to Green, Accent 6 (the first color from the right in the top row of theme colors). 
11. Change the values in the Option2 worksheet. 
    1. Change the amount borrowed (cell B3) to: 14,000
    2. Change the APR (cell B5) to: 1.9%
12. Delete any extra rows at the bottom of the worksheet where the payment due is 0 (row 41). 
13. Group the NewHybrid and Option2 worksheets. Make the following changes to both sheets at once. 
    1. Change the width of the Payment Date column (column C) to exactly 19. 
    2. Delete the extra column (column H).
    3. Unhide column G.
    4. Hide the gridlines so they do not appear onscreen.
    5. Ungroup the worksheets.
14. Hide the Working worksheet.
15. Delete the Sheet2 worksheet.
16. Change the page orientation for the NewHybrid sheet to Landscape. 
17. Modify the NewHybrid sheet so row 8 will repeat at the top of every printed page. 
18. Scale the Option2 sheet so all columns will fit on one page and all rows will fit on one page. 
19. Print preview the entire workbook.
20. Save and close the workbook.
21. Upload and save your project file. 
22. Submit project for grading.

Your task this week is to write a research paper discussing the concept of risk modeling. Please also evaluate the importance of risk models. Lastly, construct an approach to modeling various risks and evaluate how an organization may make decisions about techniques to model, measure, and aggregate risks.

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.

Complete the following assignment in one MS word document:

Chapter 1 –discussion question #1 & exercises 9 and 15 (limit to one page of analysis for question 15)

When submitting work, be sure to include an APA cover page and include at least two APA formatted references (and APA in-text citations) to support the work this week.
All work must be original (not copied from any source).

Required Books and Resources

 Business Intelligence and Analytics 

Portfolio Project: This week discuss a current business process in a specific industry. Note the following:

-The current business process itself.

-The industry the business process is utilized in.

After explaining the current situation, take the current learning from the course and:

• Explain a new technology that the business should deploy. Be specific, don’t only note the type of technology but the specific instance of technology. (For example, a type of technology is smart automation a specific type of automation is automated light-dimming technology).
• Note the pros and cons of the technology selected.
• Note various factors the business should consider prior to deploying the new technology

The above submission should be three pages in length. Remember the total length does not include the APA approved cover page or the references. There should be at least three APA approved references to support your work.

Create an array of ten strings. Write a program to join and split these strings. Feel free to use any whitespace character. Explain how the program works, when to use Python arrays, and when to use tuples, dictionaries, and sets. Explain how the program works and how it can be utilized to support an organization’s requirements.

Requirements:

• Maximum four to five pages in length is required.
