500 words APA format

Please find the attachment and please follow the instructions

Explain and provide example when it is possible that will cover chapter 6 subjects:

•Network architecture components

• Distinguish between due care and due diligence.
• Based on your experience, provide examples of due care and due diligence.

 Many new clean tech ventures have relied on funding and partnership from established corporations. Select a recently funded clean tech venture with corporate venture involvement. Did the funding impact the structure of the new venture? What does the new venture expect to gain from the backing by the larger corporation? What does the larger corporation expect to gain from being involved in the new venture?

 You will develop your research project in stages throughout the course, to include:  selecting a topic, submitting an abstract/outline, and submitting your final project (paper) for evaluation.  You must support your materials by using at least five appropriate, properly cited sources in addition to your course textbook. Your project (paper) will comprise 3000 words (not including title and reference pages).  Your project (paper) must be formatted according to APA guidelines as a Word document, double spaced, Times New Roman, 12-font, with one inch margins. 

Text book: Technology Ventures : from idea to enterprise 5th edition by Thomas Byers ISBN: 9781260048490

 Select from the following list four (4) topics and discuss. Use only 50-words max per topic to discuss and present your answer.  The discussion questions this week are from Chapter’s 3 & 4  (Jamsa, 2013).Chapter 3 topics:

• Define and describe PaaS.
• List the benefits of PaaS solutions.
• Describe potential disadvantages of PaaS.
• Describe how a cloud-based database management system differs from an on-site database.
• List the computing resources normally provided with a PaaS.

Chapter 4 topics:

• Define and describe IaaS.
• Define and describe system redundancy. Discuss how you might use IaaS to implement a redundancy plan.
• Define and describe load balancing. Discuss how you might use IaaS to implement load balancing.
• Define and describe NAS. Assume you must implement a shared file system within the cloud. What company would you select? Why? What costs should your client expect to pay for cloud-based data on a gigabyte (GB) basis?
• Define and describe colocation. Discuss how you might use IaaS to implement colocation.
• Compare and contrast a cloud-based disk storage device (with a file system) with a cloud based database.
• Compare and contrast physical, dedicated virtual, and shared virtual servers. Search the web for companies that provide each. What cost should a customer expect to pay for each?

NOTE: You are required to use at least two-peer reviewed sources (besides your textbook) to answer the above questions. 

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:

https://www.geeksforgeeks.org/measure-execution-time-function-cpp/

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.

 Need help in modifying and implementing the C++ code according to the attached problem description. (C++17 complier)
