Topic: Noise is considered technology-based security alerts that distract from true security incidents.  What kind of user training should be conducted to deal with the issue of noise? How do you strike a balance between being overwhelmed with false positives and the danger of ignoring true incidents?  What effects would false positives have on an organization?  Make sure to cite your sources.

**Note: Noise is not technical noise, but the noise created from false positives.

Assignment should follow all APA rules and include a min. of (3) citation/reference.

Create a Khanacademy account in a role of a teacher. The tutorial of Khanacademy is at https://www.youtube.com/watch?v=LfzOmc2fCPQ.  You need to create at least one class, add at least five students (create fake names for your students) to each class,  you need to pick at least two tests for yourself to take, relating to your teaching content area so that you can show students how to take test in Khanacademy in your future class.  After that, you need to view the Praxis Core in Khanacademy by typing Praxis Core in Khanacademy search engine, or, in Khanacademy, you can click on Courses, then click on Praxis Core to view it. You can take several sample tests to practice on your Praxis skills in Math, Reading, and Writing. Praxis practice is useful for you to know about how to prepare for Praxis Cores. It’s free to practice within Khanacademy.

You will review both quantitative and qualitative research.  The topic is up to you as long as you choose a peer-reviewed, academic research piece.  I suggest choosing a topic that is at least in the same family as your expected dissertation topic so that you can start viewing what is out there.  There are no hard word counts or page requirements as long as you cover the basic guidelines.  You must submit original work, however,  and a paper that returns as a large percentage of copy/paste to other sources will not be accepted.  (Safe Assign will be used to track/monitor your submission for plagiarism. Submissions with a Safe Assign match of more than 25% will not be accepted.) 

Please use APA formatting and include the following information:

• Introduction/Background:  Provide context for the research article.  What led the author(s) to write the piece? What key concepts were explored? Were there weaknesses in prior research that led the author to the current hypothesis or research question?
• Methodology:  Describe how the data was gathered and analyzed.  What research questions or hypotheses were the researcher trying to explore? What statistical analysis was used?
• Study Findings and Results:  What were the major findings from the study? Were there any limitations?
• Conclusions:  Evaluate the article in terms of significance, research methods, readability and the implications of the results.  Does the piece lead into further study? Are there different methods you would have chosen based on what you read? What are the strengths and weaknesses of the article in terms of statistical analysis and application? (This is where a large part of the rubric is covered.) 
• References

Problem-1: Create the network topology 

Write a python script to create the topology given in the Fig.1. In this topology H1, H2, H3, and H4 are hosts and S1, S2, S3, and S4 are OpenFlow switches. Specify bandwidth, delay and loss rate for each link of your choice. Assign appropriate port numbers to the switch interfaces and accordingly use in your implementation.

Fig.1

Please refer attached document  for topology(Figure)

Problem-2: Push the flow rules 

Implement a controller which pushes flow rules on switches to satisfy following traffic constraints.

· No traffic should be allowed between H3 and H1.

· The HTTP traffic between H4 and H1 should be routed through Switch S2 and any other traffic between H4 and H1 should be routed through Switch S3.

· The traffic between H3 and H2 should be routed through Switch S3.

· The traffic between remaining nodes should follow shortest path.

Problem-3: Link Bandwidth Measurement 

Once the flow rules are pushed, create necessary traffic flows to calculate instantaneous bandwidth for the following:

· Measure and print the instantaneous bandwidth on the links connected to the Switch S2.

Problem-4: Packet loss Count for a specific traffic flow 

· Calculate the packet loss count between the switches S4 and S1 for the HTTP traffic flow

H4 —S4 — S2 — S1 — H1

· Calculate the packet loss count between the switches S4 and S1 for the non-HTTP traffic flow

H4 —S4 — S3 — S1 — H1

C sharp multiple choice question

Final Paper Assignment: 

Write a 3-4 page APA formatted paper comparing your organization’s disaster recovery and business continuity plans with the best practices outlined in your course text.  Content should include, but not be limited to:  selecting the DR. team, assessing risks and impacts, prioritizing systems and functions for recovery, data storage and recovery sites, developing plans and procedures, procedures for special circumstances, and testing the disaster recovery plan. 

Your paper should include an abstract and a conclusion and a reference page with 3-5 references:

 Mrs Parker owns and operates a meat shop that processes and packages parcels of minced meat that is being sold to schools in the US. Her scales are all calibrated to perform measurement in pounds, however when the parcels are packaged, they need to be labelled in ounces. Mrs Parker has established that 1 pound is equivalent to 16 ounces. In each production cycle, 250 packs of meat are processed and the weight in pounds varies for each package. Mrs Parker is also interested in knowing the total costs, the total revenue and the total profit of each production run, given that the costs to produce and package an ounce of meat is US $0.25 and that the selling price of an ounce of meat is US $0.55. Because you are a budding Software Engineer, she has sought your assistance in creating a software solution that can be used within the business establishment. 

Required: A. Specifically identify the type of control structure which is needed to process the meat in each production run and provide a reason for your choice (4 marks) 

B. Your solution needs to represent the meat packages which are to be processed, how would you represent this appropriately in your program and what has guided your choice?  (4 marks) 

C. Construct a C# program that will solve Mrs Parker’s dilemma by making use of the choices made above. 

i. Implementation of the control structure to process the meat (2 marks) 

ii. Implementation of the meat packages to be processed (2 marks) 

iii. Calculation of costs, revenues, and profits (6 marks) 

iv. Appropriate program outputs displayed to the user
