Please Upload a source code file for this assignment. Explain your program appropriately using comments the source code.

Check the attached files of “OS Security II,”  for further details of assignment. You are to implement a Dictionary Attack with and without Password Salt program in either C++ or Python.

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

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.

Write a brief reflection on this Cloud Computing and on how it will aid your professional career and development.

• How will this  Cloud Computing impact your professional objectives?
• What were the major work-related lessons that you learned?
• How will this  Cloud Computing prepare you for further studies related to your chosen Software career?

K-dimensional trees or k-d trees organize and represent spatial data. These data structures have several applications, particularly in multi-dimensional key searches like nearest neighbor and range searches. Here is how k-d trees operate:

• Every leaf node of the binary tree is a k-dimensional point
• Every non-leaf node splits the hyperplane (which is perpendicular to that dimension) into two half-spaces
• The left subtree of a particular node represents the points to the left of the hyperplane. Similarly, the right subtree of that node denotes the points in the right half.

You can probe one step further and construct a self-balanced k-d tree where each leaf node would have the same distance from the root. Also, you can test it to find whether such balanced trees would prove optimal for a particular kind of application.

1. Conduct research on the future directions for external storage technologies.
2. Compile a list of the various flash memory devices available today on the market. Include key features and approximate prices for each type

Please go through question document completely before providing the answer

Topic :Physical security

Students will create a Disaster Recovery Plan for either the organization they work for or one they wish to work for in the future.  The plan will follow the template/example provided.

**Even though this is a technical document, for academic purposes, all sources should be cited and referenced.

***Student may modify some of the sections per the company they have selected but all students will need to complete a DR Plan for the Portfolio Requirement.  

****SafeAssign should be turned on and reviewed since it will flag a lot of the common elements but we want to make sure the students are writing the content from scratch.

Case Study 3.1

Read “Can We Trust Big Data?” (see attached file)
Answer the questions

Please use this strategy when you analyze a case:

1. Identify and write the main issues found discussed in the case (who, what, how, where and when (the critical facts in a case).
2. List all indicators (including stated “problems”) that something is not as expected or as desired.
3. Briefly analyze the issue with theories found in your textbook or other academic materials. Decide which ideas, models, and theories seem useful. Apply these conceptual tools to the situation. As new information is revealed, cycle back to sub steps a and b.
4. Identify the areas that need improvement (use theories from your textbook)
   • Specify and prioritize the criteria used to choose action alternatives.
   • Discover or invent feasible action alternatives.
   • Examine the probable consequences of action alternatives.
   • Select a course of action.
   • Design and implementation plan/schedule.
   • Create a plan for assessing the action to be implemented.
5. Conclusion (every paper should end with a strong conclusion or summary)

Writing Requirements

• 3–5 pages in length  (excluding cover page, abstract, and reference list)
• APA format, Use the APA template located in the Student Resource Center to complete the assignment.
• Please use the Case Study Guide as a reference point for writing your case study.

Discussion 3.1

If the following data were stored as rasters, which ones would be discrete and which would be continuous: rainfall, soil type, voting districts, temperature, slope, and vegetation type?

WRITTEN INTERVIEW QUESTIONS

DOCTORAL CANDIDATES SHOULD PROVIDE AN AUTHENTIC PERSONAL STATEMENT TO EACH OF THE FIVE FOLLOWING QUESTIONS/PROMPTS REFLECTING ON THEIR INTERESTS. IN THE EVENT THAT ANY OUTSIDE RESOURCES ARE USED, RESOURCES SHOULD BE CITED IN APA FORMAT. SUBMISSIONS SHOULD BE A MAXIMUM OF 500 WORDS OR 125 WORDS PER QUESTION/PROMPT. IT IS BEST TO RESPOND TO EACH PROMPT/QUESTION INDIVIDUALLY FOR CLARITY OF THE REVIEWER. WRITING SAMPLES SHOULD BE SUBMITTED IN MICROSOFT WORD FORMAT AND INCLUDE THE CANDIDATE’S NAME.

1. PROVIDE A BRIEF INTRODUCTION FOCUSING ON YOUR EDUCATION, CAREER, AND DECISION TO APPLY TO UNIVERSITY OF THE CUMBERLANDS.

2. IN RELATION TO YOUR DOCTORAL PROGRAM APPLICATION, WHAT AREA OF RECENT RESEARCH IN THE FIELD WOULD YOU WANT TO STUDY, AND WHY?

3. HOW DOES YOUR CURRENT VOCATION RELATE TO YOUR APPLICATION TO THE DOCTORAL PROGRAM?

4. HOW WILL YOUR EXPERIENCES AND PERSONAL SKILLS HELP YOU TO BE SUCCESSFUL IN YOUR PROGRAM?

5. WHAT LONG-TERM GOALS DO YOU HAVE FOR APPLYING YOUR LEARNING FROM YOUR DOCTORAL PROGRAM?

Throughout the chapter, you have reviewed various examples of B2B and B2C stores where 1-1, 1-M, and M-M relationships are portrayed. Can you provide example use cases where a business would need data to be fairly rigid, applying a 1-1 model? How about fairly lenient, applying a M-M model?
