Problem 2-4. 3G/4G

While GSM is ubiquitously deployed, 3rd and 4th generation technologies such as UMTS and LTS are wide spread today. This question explores some of the security aspects of 3G/4G systems, especially as they relate to GSM. Universal Mobile Telecommunications System (UMTS) is a 3G system based on the GSM standard. The authentication and key agreement procedure in UMTS is similar to GSM, with some notable differences:

•The security algorithms and protocols used are negotiated between the operator and the mobile station during authentication.

•Both a cipher key and an integrity key are derived during authentication.

•In addition to the RAND challenge, the mobile network sends an AUTN message that contains a Message Authentication Code (MAC).

Research the UMTS authentication and key agreement (AKA) to answer the following questions:

(a) Briefly explain the purpose of the AUTN message.

(b) Assume Eve observes a < RAND, AUTN > pair for a particular IMSI during the device’s authentication. What prevents an attacker from replaying this same < RAND, AUTN > pair? Explain your answer; you may need to examine the 3GPP UMTS spec and AUTN messages in more detail to answer.

(c) Xavier Breath believes that both the AUTN and the integrity-protected protocol negotiation messages are required to ensure mutual authentication and prevent Manin-the-Middle attacks. Explain why, or argue why not.

(d) Xavier further argues that the UMTS authentication protocol prevents downgrade attacks (for instance where the mobile station is instructed to use no encryption). Explain why Xavier is correct or incorrect.

Long Term Evolution (LTE) is a popular 4G system enjoying increased deployment.

(e) Briefly describe at least two differences between EPS-AKA (LTE’s authentication and key agreement) and UMTS’s AKA.

Imagine that you have been tasked with creating a training and development program for midlevel business managers in an organization (you can use your actual organization or one that you create). A midlevel manager is defined as a manager of managers. You have to present your proposed training program to your supervisor. To do this, you must decide on a training model, conduct a needs analysis, write learning objectives, and create the content of the training. For your assignment, you will create a 12- to 14-slide presentation (not counting the title and reference slides) that includes specific information as outlined below.

The topic of the training can be any subject relevant to a midlevel manager that we covered in the course, such as how to deliver real-time coaching feedback, how to communicate unfavorable news to employees (e.g., compensation status changes), or how to communicate that a complaint has been made against an employee concerning harassment. If you are unsure that your topic is appropriate, contact your professor for approval.

  • Be sure to include the information below in your PowerPoint presentation.
  • Discuss your selected training process model, and describe why you recommend this model.
  • Explain the steps you would have taken to conduct a needs analysis.
  • State how this training links to the organizational objectives.
  • Provide a sample of two measurable course objectives (from input objectives through impact objectives).
  • Present one of the program’s completed modules. For example, this should be one or two of the objectives that inform or engage the participants in an activity.

Be sure to cite any sources used in a reference slide with proper APA style. In addition, a minimum of one academic source that was not used in the Unit III Lesson or listed in required reading must be used, cited, and referenced. If you need assistance, the CSU library staff can help you with your research for this assignment. You may also use the slide notes function to explain slide contents as necessary, but this is not required.

Prepare a word written report describing the culture of Walmart. Your analysis should consider: the fundamental type of organizational culture (see competing values framework pp.554-559) based on the way the culture impacts employee behavior; what practices keep the culture alive; how do employees learn the organization’s culture; and, how does the organization’s culture promote or inhibit organizational change. In your analysis, be sure to identify at least several “signs” that you feel best demonstrate the organization’s culture (e.g., stories, rituals, material symbols, language).

    The Electronic Health Record has become the primary tool for population health studies and the development of evidence-based medicine. 

    Since all the Virtual Lab assignments have been moved to this semester&#39;s Professional Practice Experience, the main assignments for this course will be related to health analytics and how the data in the EHR is used. 

    The first step will be to download R Studio to your computer so that you can take data from clinical databases or EHRs and analyze the data to derive meaningful information that will improve healthcare. 

    Watch the following YouTube Video – Getting Started with R and R Studio – and download R Studio to your computer. (If you need the video to be larger click on the YouTube symbol at the bottom of the screen to watch it in YouTube directly.)  

     

    Once you have downloaded R Studio you can watch another YouTube video that shows you how to do basic commands and set up your R Studio for data analysis –
