Plagiarism can take different appearances in different fields of academic study, but it always comes down to not appropriately and accurately identifying a source every time information from the source appears.For a case study of plagiarism in the field of computer science, read the following article:Pedersen, T. (2001, April 19). A plagiarism case study (Links to an external site.) . https://www.d.umn.edu/~tpederse/Docs/A-Plagiarism-Case-Study.pdfAfter you read Pedersen’s case study, complete the following in your initial discussion post:1. Create your own example of plagiarism2. Provide an example of a way to cite the source properly3. Devise the punishment that you think is appropriate for the plagiarism example you created. Write a paragraph explaining how this punishment would be implemented.

ScenarioYou are a security professional for Blue Stripe Tech, an IT services provider with approximately 400 employees. Blue Stripe Tech partners with industry leaders to provide storage, networking, virtualization, and cybersecurity to clients.Blue Stripe Tech recently won a large DoD contract, which will add 30 percent to the revenue of the organization. It is a high-priority, high-visibility project. Blue Stripe Tech will be allowed to make its own budget, project timeline, and tollgate decisions.As a security professional for Blue Stripe Tech, you are responsible for developing security policies for this project. These policies are required to meet DoD standards for delivery of IT technology services to the U.S. Air Force Cyber Security Center (AFCSC), a DoD agency.To do this, you must develop DoD-approved policies, standards, and control descriptions for your IT infrastructure (see the “Tasks” section in this document). The policies you create must pass DoD-based requirements. Currently, your organization does not have any DoD contracts and thus has no DoD-compliant security policies, standards, or controls in place.

Your submission must include the following information in the following format:DEFINITION: a brief definition of the key term – (the definition should come from the article)SUMMARY: Summarize the article in your own words- this should be in the 200-word range. Be sure to note the article’s author, note their credentials and why we should put any weight behind his/her opinions, research, or findings regarding the key term.REFERENCE: The source for the analysis must be listed at the bottom of the submission – APA format required. Use only peer-reviewed journal articles for these assignments. Refrain from using blogs, .com’s, or other unreliable internet sources. Be sure to use the headers (Definition, Summary, Discussion, Reference) in your submission to ensure that all aspects of the assignment are completed as required. Any form of plagiarism, including cutting and pasting, will result in zero points for the entire assignment. Further, any flagged documents will result in zero points for the assignment. Flagged documents mean that an attempt at plagiarism exists, or manipulation of the Turnitin process has been attempted. This is unacceptable conduct and will not be tolerated.

After creating an initial draft of the risk management plan, the next step is to create a draft of the risk assessment plan.For this part of the project:Research risk assessment approaches.Create an outline for a basic qualitative risk assessment plan.Write an introduction to the plan explaining its purpose and importance.Define the scope and boundaries for the risk assessment.Identify data center assets and activities to be assessed.Identify relevant threats and vulnerabilities. Include those listed in the scenario and add to the list if needed.Identify relevant types of controls to be assessed.Identify the key roles and responsibilities of individuals and departments within the organization as they pertain to risk assessments.Develop a proposed schedule for the risk assessment process.Complete the draft risk assessment plan detailing the information above. Risk assessment plans often include tables, but you choose the best format to present the material. Format the bulk of the plan similar to a professional business report and cite any sources you used.

Discussion TopicThis week’s topic is Networks.Regarding the company you are writing about in your project – what issues will you have with NETWORKS between your Data Analytics function, your BIG DATA storage, your cloud presence, and your source data.For instance, are these things in the same place, or are they separated across the internet?If your data is mostly in Social Media, then what is the network path that it will traverse to get into your data warehouse?Where is your application software? Is it in the cloud with your data or is it in the data center with your data – or is there some other kind of arrangement?Is HIGH-SPEED communications a requirement for your DATA ANALYTICS function? If so why? If not why not?The answers to all of this will vary according to your different company designs so you’re going to need to start your answers by saying something like “My customers will get monthly reports …” or maybe “The data I am collecting happens in real time….”.]Other students should be able to read at least a little bit about your planned setup of the DA function at your chosen business and maybe add some suggestions on how your network should be setup. Consider this to be some FREE CONSULTING for your next assignment!!!250+ words, APA format, and one reference please603 Discussion 7Sub: Network and Information SecurityDiscussion TopicMalicious Code, or Malware, attacks all three information security properties: Confidentiality, Integrity, and Availability.

Do you foresee that the traditional computer will be replaced by mobile and smart technologies as a primary device form factor in the near future? If one looks at the world of education for example, the use of Google Chromebooks and Apple iPads are now running the majority of school infrastructures. Mobile apps replace traditional software. Can the same hold true for corporate enterprises today?

International Foodies is an importer of exotic foods from all over the world. You landed a summer internship with the company and discovered that their product lists and the suppliers they buy from are stored in Excel workbooks. You offer to help by using your newly gained knowledge of Access to create a relational database for them. You will begin by importing the workbooks from Excel into a new Access database. Your manager mentions that she would also like a table that specifies food categories so that you can relate the products you sell to specific categories in the database. You will create a table from scratch to track categories, create relationships between the tables, and create some baseline queries.Start Access. Open the downloaded Access file named Exp19_Access_Ch2_Cap_Foodies. Grader has automatically added your last name to the beginning of the filename. Save the file to the location where you are storing your files.You will examine the data in the downloaded Excel worksheets to determine which fields will become the primary keys in each table and which fields will become the foreign keys so that you can join them in the database.Open the Suppliers.xlsx Excel workbook, examine the data, and close the workbook. Open the Products.xlsx Excel workbook, examine the data, and close the workbook.You will import two Excel workbooks that contain supplier and product information into the database.Click the External Data tab, click New Data Source, point to From File in the Import & Link group, and then select Excel. Navigate to and select the Suppliers.xlsx workbook to be imported as a new table in the current database. Select First Row Contains Column Headings. Set the SupplierID field Indexed option to Yes (No Duplicates). Select SupplierID as the primary key when prompted and accept the table name Suppliers. Do not save the import steps.
