Apply the Kandias et al (2010) insider threat prediction model to the Societe Generale incident (Sayer & Wailgum 2008) to analyse motive, capability and opportunity. Discuss whether multi-factor authentication would be an effective defense against this type of compromise, including consideration of different types of multi-factor authentication.

A research design is like a blueprint for conducting research. It guides the researcher in determining when and how often the data will be collected, what data will be collected and from whom, and how the collected data will be analyzed. While there are several research designs available, the most common designs associated with quantitative research include true experiments, quasi- experiments, pre-experiments and correlations. Instructions: First, select one quasi-experimental design and develop an example of a study that would require that design. Identify the independent and dependent variables, and discuss the necessary conditions required for that design. Then, answer the following questions: How could you change this study to make it a true experiment? What would be the advantages of using a true experimental design over a quasi-experimental design? In what situations might a quasi-experimental design be preferred over a true experimental design?

PowerPoint Presentation Instructions In this assignment, you will create a presentation for your organization to explain how successful collaboration can improve success and provide competitive advantages. Scenario: Your organization has used a variety of collaboration systems developed by some project managers. Some of these systems were successful while others were not. Your organization has one unique challenge—many of your employees are staffed at other locations or work from home (telework). You would like to standardize the collaboration process to improve team communication for all company projects. In your presentation, you should include the elements listed below. Explain why collaboration information systems (IS) are important from the organization’s perspective. Discuss how collaboration tools can improve team communication. Identify three tools that will be used for synchronous communications and three tools that will be used for asynchronous communications. Be sure to explain why you made these choices. Describe how project files, such as Microsoft (MS) Word, MS Excel, MS Project, and MS Visio, will be shared with team members. Be sure to explain the rationale behind your choice. Explain how the task list for managing tasks will be shared with team members. Be sure to explain the rationale behind your choice. Discuss how this new collaboration IS could provide competitive advantages for your organization. Your presentation should be a minimum of six slides in length (not counting the title and reference slides). Use of images, graphics, and diagrams is encouraged. You can use an industry of your choosing or examples from your personal or professional experiences in developing this assignment. You can also use the resources in the Unit II Suggested Reading section to assist you with this assignment. Be sure to follow the 7×7 rule (i.e., there should be no more than 7 words per line and no more than 7 lines per slide). You are required to use speaker notes to discuss the bullet points on your slides. You must use at least two academic resources to support your presentation, and you must cite (in APA format) any information on your slides or in your speaker notes that came from these sources.

Instructions: This is an individual assignment. Use the blackboard to submit your word file with answers by 11:59 pm on the due date (no hard copies please). Late submissions will receive a zero grade. Start working on this early.     1.  Business case: Analyze the following business case and provide your recommendations. Big E. Bank  Nancy Smith is the director of network infrastructure for Big E. Bank (BEB). BEB has just purchased Ohio Bank (OB), a small regional bank that has 30 branches spread over Ohio. OB has a WAN connecting five cities, in which it has branches, to OB’s main headquarters in Columbus. It has a series of MANs in those cities (MAN is a “Metropolitan Area Network”, which usually spans a city), which in turn connect to the LANs in each of the branches. The OB network is adequate but uses very different data link, network and transport protocols than those used by BEB’s network. Smith’s task is to connect OB’s network with BEB’s network. She has several alternatives. Alternative A is to leave the two networks separate but install a few devices in OB’s headquarters to translate between the set of protocols used in the BEB network and those in the OB network so that messages can flow between the two networks. Alternative B is to replace all the WAN, MAN, and LAN network components in OB’s entire network so that OB uses the same protocols as BEB and the two can freely communicate. Alternative C is to replace the devices in OB’s WAN (and possibly the MANs) so that each city (or each branch, if the MANs are replaced as well) can communicate with the BEB network but leave the LANs in individual branches unchanged. In this case, the device connecting the MAN (or the branch) will translate between the OB protocols and the BEB protocols. Your job is to develop a short list of pros and cons for each alternative and make a recommendation.       2. What are the network applications? Give two examples.       3. What is packet switching, and why is packet switching relevant to the Internet?   4. Give a brief explanation of the layers in the ISO Open system Interconnection model.             5. Describe types of interferences and how to mitigate them.             6. Describe multi-mode and single-mode fiber and their limitations.
