Learning Objectives and Outcomes

• Examine IT infrastructure policies.
• Describe IT infrastructure policies based on the scenario given.

Scenario

You work for a large, private health care organization that has server, mainframe, and RSA user access. Your organization requires identification of the types of user access policies provided to its employees.

Sean, your manager, was impressed with the work you did on User Domain policies. This time, Sean is asking you to write descriptions for policies that affect server, mainframe, and RSA user access. 

Assignment Requirements

Research policies for each affected IT infrastructure domain, and place them into a table with an introduction explaining the following questions: Who? What? When? Why? Be sure to add a conclusion with a rationale for your selections. Reference your research so your manager may add or refine this report before submission to senior management.

Submission Requirements

• Format: Microsoft Word
• Font: Times New Roman, 12-Point, Double-Space
• Citation Style: Your school’s preferred style guide
• Length: 1–2 pages

Answering questions

Note: This one IP is worth 200 points. Parts 1 and 2 together are worth 100 points. Part 3, which is “summative” is worth 100 points. Part 1: In a two-phase, total-order multicast system, messages are sent in the following sequence from node S to G1 and G2. G1 and G2 are the members of the group. 1. S sends m1 to G1 2. S sends m1 to G2 3. S sends m2 to G2 4. S sends m2 to G1 Use the basic implementation of the Lamport clock. The clock s at each node start at: S: 4, G1: 6, G2: 1 Show the exchange of messages and their acknowledgments in a clock diagram using the basic implementation of Lamport’s clock. In which order and at what times are m1 and m2 delivered? Part 2. Draw a state diagram of Maekawa’s voting algorithm on the slide “Maekawa’s algorithm” in the “Distributed mutual exclusion” slide set. Note that the state diagram is from the point of view of any one of the nodes, called “this” node below. The state diagram cannot show the states of other nodes. i) Start with the basic case where “this” node wants the lock, gets it, and then releases it, and no other node wants the lock at the same time. In this case, “this” node goes through all the states in this order: Released and not voted Wanted and not voted Wanted and voted Held and voted Released and voted (Back to) Released and not voted Events are: acquire for when “this” node wants the lock release for when “this” node gives up the lock. 8/7/20 3:01 PM 15 request_received, reply_received, and release_received when a message from any node arrives at “this” node. The state diagram is similar the one of Ricart and Agrawala’s state machine (in the Distributed Mutual Exclusion PowerPoint deck) but has more states. *** If you do part i) more or less correctly, you will earn most of the points. *** ii) The complete solution includes the situations where “this” node votes on requests from other nodes. The states are the same as above, but there are additional transitions and actions. Use the “Maekawa scenario” slide in the Distributed Mutual Exclusion slide set, or Fig. D-10 in the Study Guide. Warning: There is an incorrect solution for this problem on the Web. It has extra, incorrect states. Part 3 (100 points): Summarize the course in your own words in an essay of 5-6 pages or so. Feel free to reuse any relevant DB posts as well as Unit 3 IP, but please correct any errors found. Edit it all into one paper that reads nicely from top to bottom and is styled according to APA. Include at a minimum: • How threads and safe objects interact. This can be in general or based on Ada or Java. • Entity-life modeling: the idea of finding event-sequence models of the domain and map them onto thread architectures in the software. Deadlock prevention. • The use of logical clocks for communication and/or for distributed mutual exclusion.  

• As the HU Investment Firm cybercrime expert, you are required to create a Cybercrime Mitigation Plan. The overall cybercrime mitigation plan should be written with a minimum of two to three sentence description of what the outline will cover under each section. 
• COPY THE CONTEXT FROM UNIT 5
• Use the following website as a guide to creating your Risk  Mitigation Plan
  • https://security.berkeley.edu/incident-response-planning-guideline (Links to an external site.)

Keep the following structure in mind as you develop your mitigation plan. You want to avoid or transfer as much serious risk as possible and have a detailed mitigation plan for the remaining risks.

Write your formal Mitigation Plan and ensure you include the following components:

• Understand the users and the needs of the users
• Research what the experts say about the needed mitigation for every element. Include that support in your report.
• Identify and evaluate recurring risks and explain in detail the plan to mitigate those risks
• Identify and explain opportunities to improve the system in order to reduce the negative impacts of some events
•  Propose a plan to promote collaboration and dialogue about risk management and mitigation planning
• Ensure that your writing is professional, well-supported, and easy to understand for non-IT people

1. HHS and the FTC recently launched an investigation into a major pharmacy chain for its information disposal practices. The regulators claimed that the pharmacy chain failed to protect customers’ sensitive financial and medical information by disposing prescriptions and labeled pill bottles in dumpsters that were accessible by the public. Based on the HIPAA (Health Insurance Portability and Accountability Act of 1996), what consequences should a company face for failing to properly dispose of customer information? For HIPAA act, you may check the website.

2. Trust is an important part of the continued growth and development of the Internet. This is particularly the case with respect to social networking. Media reports of disturbing stories and case law alike have shown some of the consequences that can arise when individuals create false social networking profiles. In a case in California, and individual established a fake MySpace profile of his former church pastor. On the profile, he posted content that suggested that the pastor used drugs and was homosexual. Can criminal charges be brought against the party that created the fake profile?

3. Read the Family Educational Rights and Privacy Act of 1974 (FERPA) at ED, discuss who has access to your educational record at APUS. Furthermore, what is the roles and responsibilities for APUS instructors and students to comply with FERPA

The attached journal article focuses on attribution theory and how it influences the implementation of innovation technologies. Two types of employee attributions are noted in the article (intentionality and deceptive intentionality), please review these concepts and answer the following questions:

1.    Provide a high-level overview/ summary of the case study

2.    Note how constructive intentionality impacts innovation implementations

3.    Find another article that adds to the overall findings of the case and note how attribution-based perspective enhances successful innovation implementations.  Please be explicit and detailed in answering this question.

Format Requirements:

1. The paper must be minimum 3 pages excluding title and references pages. 

2. Include references of at least 5 peer reviewed papers supporting your case study. 

3. The paper must comply APA Format and include a cover page, an  introduction, a body with fully developed content, a conclusion and  references.

The purpose of this programming project is to explore process synchronization. This will be accomplished by writing a program to solve the bounded buffer problem using monitor concept. Your program must be written using C or C++ and you are required to use the Pthread libraries. 

Bounded buffer is used to enable multiple producers and consumers processes to share memory. A producer can place items into the buffer only if the buffer has a free memory location to store the item. A producer cannot add items to a full buffer. A consumer can remove items from the buffer if the buffer is not empty. A consumer must wait to consume items if the buffer is empty. The “items” stored in this buffer will be integers. Your producer processes will have to insert random numbers into the buffer. The consumer processes will consume a number. 

 Discuss the team dynamics for a highly effective or ineffective team of which you were a member. Can you explain why the team performed so well or so poorly?
