 Read the attached article and write a summary of 2 and a half pages. 

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.

A project’s Work Breakdown Structure (WBS) and Gantt chart provide structure for a project. In this week’s assignment you develop both the WBS and Gantt chart for a fictitious organization. The Manage Your Health, Inc (MYH) scenario will be used in the weekly assignments for the rest of the course.

Review the Manage Your Health Scenario and follow the directions below for completing a WBS and Gantt chart.

Develop a work breakdown structure (WBS) for the project. Break down the work to Level 3 or Level 4, as appropriate. Use the Work Breakdown Structure Template and Work Breakdown Structure example in this text as guides. Upload the WBS in list form. The WBS should be based on the information that would be in a project scope of this scenario. You can review your project plan from Wk 1. 

Create a Gantt chart using the WBS you developed with Microsoft Excel or another software of your choice and approved by your instructor. Do not enter any durations or dependencies. 

Submit 2 deliverables: the WBS and Gantt Chart.

 You are the web master for the Republican Party National Committee. Prepare a risk assessment analysis for your website. Some questions to consider:

• Who is likely to attack your site?
• When are attacks likely to occur?
• What sort of attacks might take place?
• How can you best minimize attacks and protect the integrity of your site?

Security Breach Evaluation

Learning Objectives and Outcomes

• Analyze the given case study on security breach.
• Recommend controls to avoid an enterprise security breach.

Assignment Requirements

Read the text sheet named “Local Breach of Sensitive Online Data” and address the following:

Using what you have learned about security breaches, describe what measures should have been taken by the educational service and test preparation provider to avoid the security breach mentioned in the text sheet.

• Select a company of your choice and perform a case study similar to the Telenor case study described in the above article.
  • You may not have direct access to the company you select, which means you may not be able to conduct interviews, and you may not have access to all the information you would like access to.
• Your case study must follow APA guidelines (see my guide in Week 1)
• Your case study paper must be organized with the following level two headings. Use level one and level three headings as needed). 
  • Company Background
  • Company Business Strategy
  • Company IS/IT Strategy
  • IS Strategy Triangle (Read Shanardi and find other resources before arriving at the Friday meeting)
  • Strategic Alignment Model (Read Henderson and Venkatraman and find other resources before arriving at the Friday meeting)
  • Strategic Alignment Maturity Model (Read CIO wiki and find other resources before arriving at the Friday meeting)
  • Strategic Grid (Read McFarlan, McKenney, and Pyburn and find other resources before arriving at the Friday meeting)
  • Limitations (Cover the limitations of your study and paper)
  • Conclusions
• Your paper must include at least five scholarly sources beyond the resources provided on Blackboard
• Your paper must include a cover page with the names of all team members.

Review the following questions from Network security: Private communication in a public world and provide your responses in a Word document. In answering each prompt, be sure to defend your answers and explain how you have arrived at your solution.

1. Random J. Protocol-Designer has been told to design a scheme to prevent messages from being modified by an intruder. Random J. decides to append to each message a hash of that message. Why does this not solve the problem?

Hint: We know of a protocol that uses this technique in an attempt to gain security.

1. Suppose Alice, Bob, and Carol want to use secret key technology to authenticate each other. If they all used the same secret key, K, then Bob could impersonate Carol to Alice (actually any of the three could impersonate the other to the third). Suppose instead that each had their own secret key; so Alice uses KA, Bob uses KB, and Carol uses KC. This means that each one, to prove his or her identity, responds to a challenge with a function of his or her secret key. Is this more secure than having them all use the same secret key?

Hint: What does Alice need to know in order to verify Carol’s answer to Alice’s challenge?

1. Assume a cryptographic algorithm in which the performance for the good guys (the ones that know the key) grows linearly with the length of the key and for which the only way to break it is a brute-force attack of trying all possible keys. Then, suppose the performance for the good guys is adequate (e.g., it can encrypt and decrypt as fast as the bits can be transmitted over the wire) at a certain size key. Finally, suppose advances in computer technology make computers twice as fast. Given that both parties— the good guys and the bad guys— get faster computers, does this advancement in computer speeds work to the advantage of the good guys? The bad guys? Or does it not make any difference?

In each of your responses to the above scenarios, please ensure that you provide a brief explanation of why you chose to take your mentioned actions.
