Purpose
The purpose of the Unit 4 assignment is for you to engage in defining a mitigation strategy for a malware threat being introduced into the system. 
Assignment Instructions
You are a cybersecurity professional employed in a research and development firm working on medical research related to identifying effective treatments for several diseases. It is known that a similar type of research organization was recently hacked by a foreign state agent through the use of malware, and many patents and other intellectual property were stolen. Your CEO and CIO want to be certain that their organization’s systems are protected against this type of attack. They have asked you to perform a high-level risk assessment and provide a risk management approach related to this type of malware attack. Assume the following for the assignment:

The organization has an outward facing website that provides information on the research in progress and presents general news of interest to its followers. The web server housing this website is in the organization’s demilitarized zone (DMZ). The DMZ uses a single firewall system. Users can request information by submitting a form.
Servers on the internal network houses several databases. One holds all current patent information for patents held by the organization. The second database holds the researchers’ notes and all research project information for projects that are in progress. The patent database is encrypted. There is also a collaboration area where researchers that work together can share notes and ideas. A third database houses employee information. 
Also, on the internal network are an email server, print servers, and application servers.
The organization does not use any cloud computing. An incremental backup of the servers and databases is made daily and stored in the same building.
The organization has biometric identification to the external door and all internal lab rooms and server rooms. There are no security cameras. 

Use the following risk management approach to determine where compromises may exist, what the consequences of those compromises are, and controls and methods to reduce the likelihood of or severity of the compromise. Identify at least two vulnerabilities, threats, and risks. Recommend what you think is the best control for each vulnerability, threat, and risk identified.
Assignment Requirements
The paper should be at least 3 pages, use 12 pt. Times New Roman, and be in APA format.

The ability to deal with professional conflict is one of those soft skills that is very useful when working in teams. In 3-4 paragraphs, discuss the following:
Imagine you are on a team at work, and the Project Manager has asked each of the team members for their input on how the team is working together. What do you hope the other team members will say about you?
Suppose one of the team members isn’t contributing very much or providing you with something you need in order to proceed with your part of the project. How might you address the situation? Include a rationale for why you would take that approach.
What might you do if you approached the Project Manager about the issue with a teammate and the Project Manager ignored your concerns?

A family clinic contains a dataset as uploaded in the module for the final project. Identify how the following methods and techniques can be applied to the dataset to aid necessary decision support.
1. Description of the use of Information Entropy to identify the reduction in the possibility of the development of heart disease (this part may not need the dataset provided) based on changes in lifestyle
2. Your explanation must describe the random variable considered for the calculation

In your initial post, imagine that you are a user writing an email to an IT hel

In your initial post, imagine that you are a user writing an email to an IT help desk because your wireless internet is very slow.
In the email, explain what the issue is and provide some context that might help an IT professional resolve it. For example, you might state that you are having issues connecting to Wi-Fi on your computer or phone, or you are getting a 404 error when you try to access a webpage. Maybe your wireless router is blinking strangely.
You can describe an issue that you actually have experienced as a user in the past, or choose an issue that you think is common for many users to experience.
In response to two of your peers, answer the email as if you are an IT professional working at a help desk.
If you are having issues troubleshooting the user or system error because you do not have enough information, ask the user clarifying questions. Consider:

What important information do I need to know in order to troubleshoot the error?
Did the initial post provide me with enough information to identify the probable cause and to implement the fix?

If you believe that you have enough information, state your hypothesis concerning what is causing the issue.
RESPONSE 1
Dear IT Help Desk,
I am reaching out to you as I am currently experiencing significant issues with my wireless connection and would greatly appreciate your assistance.
For the past few days, my wireless internet has been intermittent and slow. This issue affects all the devices I connect to the network, including my laptop and cell phone. I have asked some of my peers if they are experiencing the same issues, however, they have all stated that they have not had any. Here are some details that might be helpful in diagnosing the problem:
When the issue is present and I run a speed test, the results are far below the speed I am supposed to be receiving compared to what I have received in the past and what my peers receive. During those times, I consistently get a download and upload speed of around 5 Mbps when others are seeing closer to 100 Mbps on both.
The slow speed is intermittent. Sometimes the speed is good, but other times the speed drops significantly. This issue occurs regardless of my relative location to the access point.
The access point nearest me appears to be functioning normally from what I can tell but I have noticed that one of the lights that was green now appears to be yellow and does not blink as quickly. I am unsure if this is related, or if this was a possible update to the access point. 
I have not noticed any error messages to indicate I have no connection to the access point, but I do experience frequent buffering when streaming videos and web pages can sometimes take a couple of minutes to load.
I have already tried rebooting my devices, but the issue persists. I also checked for any firmware updates on my equipment and applied them, but it did not resolve the problem. I would try to reset the access point, but it is high up and I would need a ladder.
Could you please investigate this issue and provide guidance on how to resolve this issue? Also, If you need any additional information or if there are specific steps I should follow, please let me know.
Thank you for your prompt attention to this matter.
RESPONSE 2
Dear IT Help Desk,
I am writing to report a persistent issue with my wireless internet connection. Over the past few days, I have been experiencing prolonged internet speeds and significant latency issues. Here are the details of the problem:
1. Devices Affected:
    My computer and phone experience slow speeds and high latency when connected to the WiFi network.
    I have tried connecting both devices in different rooms, but the issue persists regardless of location.
2. Symptoms:
    Web pages take an unusually long to load, often resulting in a 404 error before finally loading after multiple refresh attempts.
    Streaming services are buffering frequently, making it impossible to watch videos without interruptions.
    The latency is causing significant delays in online applications and video calls, which is affecting both my work and personal communication.
3. Router and Modem:
    The wireless router’s lights are blinking in a pattern I haven’t noticed before. Specifically, the internet light flashes rapidly and intermittently.
    I have tried restarting the router and the modem, which temporarily improves the situation, but the issue soon returns.
4. Network Configuration:
    I have yet to change my network settings or add new devices.
    I use a combination of 2.4 and 5 GHz bands, but both seem to be experiencing issues.
5. Interference and Signal Strength:
    The router is placed in a central location in my home, with minimal obstructions.
    No new electronic devices near the router could cause interference.
Your assistance in diagnosing and resolving this issue would be greatly appreciated. Thank you for your help.
Thank you,
Ismael Garcia Jr.

Case study
Cyber Marketing, Inc. (CMI) is a marketing company that markets its products and services to thousands of its clients across North America. As a marketing company, the products and services catalog is an important corporate asset to keep up-to-date for its clients. In order to keep its products and services updated at all times, its corporate IT infrastructure plays an important role in processing data within and between the company and the clients. The following organization chart depicts the CMI executive management team.
Org chart
Your Role
For the assignments related to this case study, you will assume the role of a Cybersecurity Manager at Cyber Marketing Incorporated. You have been educated, trained, and hired to protect the physical, logical, and operational security of CMI’s corporate information system. CMI has experienced several cyber-attacks from outsiders over the past a few years. In 2013, the Oracle database server was attacked and its customer database lost its confidentiality, integrity, and availability for several days. Although the company restored the Oracle database server back online, its lost confidentiality damaged the company reputations. CMI ended up paying its customers a large sum of settlement for their loss of customer data confidentiality. Another security attack was carried out by a malicious virus that infected the entire network for several days. While infected, the Oracle and e-mail servers had to be shut down to quarantine these servers. In the meantime, the company lost $1.2 Million in revenue and intangible customer confidence.
CMI Network Diagram
You are responsible for a corporate WAN spanning 10 remote facilities and interconnecting those facilities to the central data processing environment. Data is transmitted from a remote site through a VPN appliance situated in the border layer of the routing topology; the remote VPN connects to the internal Oracle database to update the customer data tables. Data transaction from the remote access to the corporate internal databases is not encrypted.
A bulk of the data processing for your company is handled by Oracle database on a high-end supercomputer. The trusted computing based (TCB) internal network is situated in a physically separated subnet. This is where all corporate data processing is completed and the internal support team has its own intranet web server, a SUS server, an internal DNS, an e-mail system, and other support personnel workstations. Each corporate department is segregated physically on a different subnet and shares the corporate data in the TCB network.
Additional Information
In addition to the context provided above, you will find some other considerations regarding the CMI case study below:
Recently, your network engineers report that they’ve noted a significant spike in network traffic crossing into the internal networks. They report that they cannot be certain what or who is generating this traffic, but the volume and frequency of traffic are certainly abnormal. The management is very concerned about securing the corporate confidential data and customer information.
Increasingly, CMI’s CEO Thompson attempts to outsource IT competency. In fact, you’ve been told of a plan from COO Willy to outsource network management and security functions away from your department and to a service integrator. COO Willy warns you that the political environment will only become more contentious over time; you must make a compelling case as to what value your department can bring over an integrator that can provide secure services at 40% less annual cost than you.
The interrelationship between data and operations concerns you. Increasingly, some of the 10 remote sites have been reporting significant problems with network latency, slow performance, and application time-outs against the Oracle database. The company’s business model is driving higher and higher demand for data, but your capability to respond to these problems are drastically limited.
Mobility is important for the organization to interact with the customers and other co-workers in near real-time. However, the CEO is concerned with the mobility security and would like to research for the best practice for mobile computing. The CEO is willing to implement a BYOD policy if security can be addressed.
Employees enjoy the flexibility of getting access to the corporate network using a WiFi network. However, the CEO is concerned over the security ramifications over the wireless network that is widely open to the company and nearby residents.
The company plans to offer its products and services online and requested its IT department to design a Cloud Computing based e-commerce platform. However, the CEO is particularly concerned over the cloud computing security in case the customer database was breached.
