Protocols, Services, and Data Transmission in Massive Systems

In today’s interconnected world, information systems are no longer confined to single servers or local networks; they are vast, distributed entities encompassing cloud infrastructures, global data centers, IoT devices, and millions of users. The ability to reliably, efficiently, and securely transmit data across these “massive systems” is entirely dependent on the foundational roles played by network protocols and services. Without their standardized rules and functionalities, the seamless flow of information that we often take for granted would be impossible.

Consider a scenario involving a globally distributed online service (e.g., a major social media platform, a large-scale e-commerce provider like Amazon, or a cloud computing provider like Google Cloud/AWS) that handles petabytes of data and millions of concurrent users.

In your initial post, address the following:

1. The indispensable role of protocols: Explain why network protocols are absolutely fundamental to ensuring proper data transmission in any system, big or small. Using your chosen globally distributed online service as an example, identify and briefly describe the function of at least two different network protocols (e.g., TCP, IP, HTTP, DNS, BGP, SSL/TLS) that are critical for its operation and data integrity.
2. Services for scale and reliability: Beyond raw protocols, network services provide essential functionalities that enable massive systems to operate efficiently and reliably. Identify and describe at least two critical network services (e.g., DNS, DHCP, Load Balancing, CDN, VPN, Network Monitoring) that your chosen online service would heavily rely on. Explain how each service contributes to ensuring data is properly transmitted, managed, or accessed across its massive infrastructure, emphasizing concepts like availability, performance, or security.
3. Consequences of protocol/service failure: What are the potential consequences if these essential protocols or services are misconfigured, become overloaded, or fail in a globally distributed online service? Discuss how such failures would impact data transmission, system functionality, user experience, and ultimately, the business operations and reputation of the company.

Response Requirements:

• Initial post: Your initial response should be at least 300 words, demonstrating a comprehensive understanding of network protocols and services and their critical importance in large-scale data communication.
• Reply posts: Reply to at least two classmates’ posts. In your replies, you might:
• Propose alternative protocols or services that could also be critical for their chosen system, with justification.
• Discuss how regulatory compliance or geographical distribution might influence the choice or implementation of certain protocols/services in their scenario.
• Elaborate on the challenges of managing and securing protocols and services at such a massive scale.

Scenario

You are the IT risk assessment lead at Health Network, Inc., a health services organization headquartered in Tampa, Florida. Health Network has over 700 employees throughout the organization and generates $500 million in revenue annually. The company has two additional locations in Seattle, Washington, and Arlington, Virginia. These locations support different aspects of corporate operations. Each facility is located near a data center, where production systems are located and managed by third-party data-center hosting vendors.

Health Network has three main products:

1. HNetExchange is the primary source of revenue for the company. The service handles secure electronic medical messages that originate from its customers, such as large hospitals, which are then routed to receiving customers such as clinics.
2. HNetPay is a web portal used by many of the companys HNetExchange customers to support the management of secure payments and billing. The HNetPay web portal, hosted at Health Network production sites, accepts various forms of payments and interacts with credit-card processing organizations, much like a web commerce shopping cart.
3. HNetConnect is an online directory that lists doctors, clinics, and other medical facilities to allow Health Network customers to find the right type of care at the right locations. It contains doctors personal information, work addresses, medical certifications, and types of services that the doctors and clinics offer. Doctors are given credentials and are able to update the information in their profiles. Health Network customers, which are hospitals and clinics, connect to all three of the companys products using HTTPS connections. Doctors and potential patients are able to make payments and update their profiles using internet-accessible HTTPS websites.

Health Network operates in three production data centers that provide high availability across the companys products. The data centers host about 1,000 production servers, and Health Network maintains 650 corporate laptops and company-issued mobile devices for its employees.

A previous risk assessment identified the following threats:

• Potential loss of data due to inappropriate hardware decommission
• Potential loss of protected health information (PHI) from lost or stolen company-owned assets, such as mobile devices and laptops
• Potential data loss due to corrupt production data resulting from a systems outage
• Internet threats from hackers and other malicious actors
• Insider threats due to social engineering, installation of malware and spyware
• Changes in the regulatory landscape that may impact operations

Based on the findings of this risk assessment, Health Network administration has determined that the existing risk management plan does not take into account the above threats and is therefore out of date. You have been assigned to develop a new plan.

Directions

For this assignment, you will create a risk management plan for Health Network that contains the following objectives:

1. Importance: Explain the plans purpose and importance for the key stakeholders of the organization.
2. Scope: Define the scope and boundaries of the plan.
3. Risks: Identify the organizations primary internal and external risks based on the local environments where facilities are located.
4. Safety: Describe physical and safety considerations associated with the identified risks.
5. Business Impact: Conduct a business impact analysis (BIA) that determines the probability and significance of certain risky events and their potential impact on the various aspects of Health Networks business.
6. Mitigation: Identify strategies to mitigate these risks and to allow Health Network to continue operating (business continuity plan (BCP) and disaster recovery plan (DRP)) if these risks occur.

What to Submit

To complete this project, you must submit the following:

Risk Management Plan (5 to 10 pages)

The recommended length for this plan is 5 to 10 pages, single spaced

Paper A: Application of a decision making framework to an IT-related ethical issue.

This assignment is an opportunity to explore and apply a decision making framework to an IT-related ethical issue. A framework provides a methodical and systematic approach for decision making.

UMGC Module 2 – Methods of Ethical Analysis (see LEO Content Readings for week 2) describes three structured frameworks that may be used for ethical analysis, namely Reynolds Seven-Step Approach, Kidders Nine Steps, and Spinellos Seven-Step Process. There are several ways described in UMGC Module 2 to systematically approach an ethical dilemma, and while each of the frameworks described has its merits, each will result in an ethical decision if straightforwardly, objectively, and honestly applied.

In addition, consider the ethical theories described in Module 1 Introduction to Theoretical Ethical Frameworks (see LEO Content Readings for week 1) which help decision makers find the right balance concerning the acceptability of and justification for their actions. A separate write-up of the ethical theory that supports your decision is part of the following requirements.

For this paper, the following five elements must be addressed:

• Describe a current IT-related ethical issue: Since this is a paper exercise, not a real-time situation, you may want to construct a brief scenario where this issue comes into play, and thus causes an ethical dilemma. The dilemma may affect you, your family, your job, or your company; or it may be a matter of public policy or law that affects the general populace. See the list below for a list of suggested issues, which may be a source of ethical dilemmas.
• Define a concise problem statement that is extracted from the above description or scenario. It is best if you define a specific problem caused by the dilemma, that needs a specific ethical decision to be made, that will solve the dilemma. Be aware that if it is a matter of public policy or law, that it may require a regulatory body or congressional approval to take action to implement a solution.
• Analyze your problem using one of the structured decision-making frameworks chosen from Module 2. Make sure that you identify the decision-making framework utilized. In addition, the steps in the decision-making framework selected must be used as major headings in the Analysis section.
• Frameworks from Module 2: Ethical Decision Making; Training Ethical Decision Making; Managers Role in Ethical Conduct; and Codes of Conduct
• Consider and state the impact of the decision that you made on an individual, an organization, stakeholders, customers suppliers, and the environment, as applicable!
• State and discuss the applicable ethical theory from Module 1 that supports your decision.

Concerning your paper:

• Prepare a minimum 3- 5 page, double-spaced paper and submit it to the LEO Assignments Module as an attached Microsoft Word file.
• Use headings for each topic criteria
• Provide appropriate American Psychological Association (APA) source citations for all sources you use. In addition to critical thinking and analysis skills, your paper should reflect appropriate grammar and spelling, good organization, and proper business-writing style.
• Include a Cover Page with your Name, the UMGC/Name of the Class, and the Title of the Paper.

For example, Kidders approach has nine steps, which are:

• Recognize that there is a moral issue.
• Determine the actor (whose moral issue is it?).
• Gather the relevant facts.
• Test for right-versus-wrong issues.
• Test for right-versus-right paradigms (what sort of dilemma is this?).
• Apply the resolution principles (ends-based, rule-based, or care-based).
• Investigate the “trilemma” options (look for common ground or compromise).
• Make the decision.
• Revisit and reflect on the decision. (Kidder, 1995, p. 183-187)

Reminder: Each of the steps for whatever framework that you select must be a major heading in the Analysis section of your paper.

Here are some suggested issues for you to consider, the additional text is designed to help you flesh out the issue:

1. Privacy on the Web: What is happening now in terms of privacy on the Web? Think about recent abuses and improvements. Describe and evaluate Web site policies, technical and privacy policy protections, and current proposals for government regulations.
2. Personal Data Privacy Regulations in Other Countries: Report on personal data privacy regulations, Web site privacy policies, and governmental/law enforcement about access to personal data in one or more countries; e.g., the European Union. This is especially relevant as our global economic community expands and we are more dependent on non-US clients for e-business over the Internet.
3. Computer-Based Crimes: Discuss the most prevalent types of computer crimes, such as Phishing. Analyze why and how these can occur. Describe protective measures that might assist in preventing or mitigating these types of crimes.
4. Government Surveillance of the Internet: The 9/11 attacks on the US in 2001 brought many new laws and permits more government surveillance of the Internet. Is this a good idea?
5. The Digital Divide: Does it exist; what does it look like; and, what are the ethical considerations and impact?
6. Privacy in the Workplace – Monitoring Employee Web and E-Mail Use: What are current opinions concerning the monitoring of employee computer use. What policies are employers using? Should this practice of monitoring, be authorized or not?
7. Medical Privacy: Who owns your medical history? What is the state of current legislation to protect your health information? Is it sufficient? There are new incentives with federal stimulus financing for health care organizations to develop and implement digital health records.
8. Software Piracy: How many of you have ever made an unauthorized copy of software, downloaded software or music (free or for a fee), or used copyrighted information without giving proper credit or asking permission? Was this illegal or just wrong? How is this being addressed?
9. Consumer Profiling: With every purchase you make, every Web site you visit, your preferences are being profiled. What is your opinion regarding the legal authority of these organizations to collect and aggregate this data?
10. Biometrics & Ethics: Your fingerprint, retinal-vessel image, and DNA map can exist entirely as a digital image in a computer, on a network, or in the infosphere. What new and old ethical problems must we address?
11. Social Networking: What are some of the ethical issues surrounding using new social networks? How are these now considered for business use? What are business social communities? Are new/different protections and security needed for these networks?
12. Gambling in Cyberspace: Is it legal? Are there national regulations and/or licensing? What are the oversight and enforcement requirements? Are there international implications? What are the social and public health issues?
13. Pornography in Cyberspace: For example, the U.S. Supreme Court ruling protecting as free speech computer-generated child pornography
14. Medicine and Psychiatry in Cyberspace: Some considerations include: privacy issues; security; third-party record-keeping; electronic medical records; access to information, even by the patient (patient rights); access to information by outsiders without patient knowledge; authority to transfer and/or share information. Are there any policies proposed by professional organizations?
15. Counterterrorism and Information Systems: Your protection versus your rights
16. Open-source Software versus Closed-source Software: Ethical ramifications and impact on intellectual property law
17. Creative Commons Licenses: How do they work and what are the legal and ethical impacts and concerns?
18. Universal ID card: What is the general position of the U.S. government about issuing each individual a unique ID card? Which individual U.S. government agencies have already provided a unique ID card? What steps have been taken to include individual ID information electronically in passports? How is privacy and security provided?
19. Video Games: Does playing video games distract from everyday responsibilities? Do video games correlate with real world violence? Why do game creators continually increase the violence of video games? What is video game addiction?
20. Cyberbullying: What is cyberbullying and what can be done to stop it?
21. Net Neutrality: What is the current position of the federal government and is it fair to all?

In addition to the list, It is beneficial to include new digital technologies that are emerging/have emerged, such as GenAI, Genome editing, alternate and virtual reality, remote work and monitoring to name a few.

We will be writing a 1500 word paper for a writing assignment I have to do. I will give you the requirements and what it is about. Based on the material covered in the Individual section of this course, this paper will investigate how to put some of the concepts presented into practice. IT is a highly complex environment, not just from the technology standpoint, but from the need to release software promptly. Applications are critical to keeping a business moving; if the business doesnt move, it does not make money. A business will probably lose customers if the applications are not working for an extended period of time.

What will be covered in this paper are some of the non-technical components in IT that need to be understood and utilized as a plan for a viable and growing business. We will use a model application as the conceptual backdrop to discuss these concepts. For this assignment, we will use an application in the business setting of the Rock Coast Bank. The application is a new mobile app that uses Blockchain as the mechanism to hold critical information about the users information (PII – Personally Identifying Information and possibly SPI – Sensitive Personal Information).

IT 140 Module Six Milestone Guidelines and Rubric

Overview

As you are preparing for your final text game project submission, the use of dictionaries, decision branching, and loops will be an important part of your solution. This milestone will help guide you through the steps of moving from your pseudocode or flowchart to code within the PyCharm integrated development environment (IDE).

You will be working with the same text-based game scenario from Projects One and Two. In this milestone, you will develop code for a simplified version of the sample dragon-themed game. The simplified version involves moving between a few rooms and being able to exit the game with an exit command. In the simplified version, there are no items, inventory, or villain. Developing this simplified version of the game supports an important programming strategy: working on code in small iterations at a time. Completing this milestone will give you a head start on your work to complete the game for Project Two.

Prompt

For this milestone, you will be submitting a working draft of the code for a simplified version of the text-based game that you are developing for Project Two. You will focus on displaying how a room dictionary works with the move commands. This will include the if, else, and elif statements that move the adventurer from one room to another.

1. Before beginning this milestone, it is important to understand the required functionality for this simplified version of the game. The game should prompt the player to enter commands to either move between rooms or exit the game. Review the and the to see an example of the simplified version of the game. A video transcript is available:
2. IMPORTANT: The Move Between Rooms process in the Milestone Simplified Text Game Flowchart is intentionally vague. You designed a more detailed flowchart or pseudocode for this process as a part of your work on Project One. Think about how your design will fit into this larger flowchart.
3. In PyCharm, create a new code file titled ModuleSixMilestone.py. At the top of the file, include a comment with your name. As you develop your code, you must use industry standard best practices, including in-line comments and appropriate naming conventions, to enhance the readability and maintainability of the code.
4. Next, copy the following dictionary into your PY file. This dictionary links rooms to one another and will be used to store all possible moves per room, in order to properly validate player commands (input). This will allow the player to move only between rooms that are linked.

Note: For this milestone, you are being given a dictionary and map for a simplified version of the dragon-themed game. Make sure to read the code carefully so that you understand how it works. In Project Two, you will create your own dictionary based on your designs.

#A dictionary for the simplified dragon text game

#The dictionary links a room to other rooms.

rooms = {

‘Great Hall’: {‘South’: ‘Bedroom’},

‘Bedroom’: {‘North’: ‘Great Hall’, ‘East’: ‘Cellar’},

‘Cellar’: {‘West’: ‘Bedroom’}

}

1. Next, you will develop code to meet the required functionality, by prompting the player to enter commands to move between the rooms or exit the game. To achieve this, you must develop the following:

• A gameplay loop that includes:
• Output that displays the room the player is currently in
• Decision branching that tells the game how to handle the different commands. The commands can be to either move between rooms (such as go North, South, East, or West) or exit.
• If the player enters a valid move command, the game should use the dictionary to move them into the new room.
• If the player enters exit, the game should set their room to a room called exit.
• If the player enters an invalid command, the game should output an error message to the player (input validation).
• A way to end the gameplay loop once the player is in the exit room

1. TIP: Use the pseudocode or flowchart that you designed in Step #4 of Project One to help you develop your code.
2. As you develop, you should debug your code to minimize errors and enhance functionality. After you have developed all of your code, be sure to run the code to test and make sure it is working correctly.

• What happens if the player enters a valid direction? Does the game move them to the correct room?
• What happens if the player enters an invalid direction? Does the game provide the correct output?
• Can the player exit the game?

What to Submit

Submit your ModuleSixAssignment.py file. Be sure to include your name in a comment at the top of the code file.
