Only working on Section 3 for this assignment add to the file attached (the first part, including Section 1 & 2, has been completed).
Throughout this course, you will be working with a scenario in which some basic background information is provided about a consulting firm. This scenario and information is typical in many companies today. You are tasked to select a company that you are familiar with that is facing a similar situation. The company can be real or fictitious, but the framework and problems that it faces should be similar. The assignments that you complete each week are based on the problems and potential solutions that similar companies may face. The end goal for these assignments is to analyze the problems that the company faces with respect to the upcoming audit and to provide guidance on how it can provide security for its infrastructure.
Description
Create the following section for Week 3:
The case study company has provided you with the flexibility to identify many different information systems that are used by the employees. Some systems need strict access control, whereas others should be available to everyone. What access control methods need to be employed for the various systems? How can the company protect the new consultant network while providing the protection of data that the stakeholders and customers require?
In addition, you have been asked to describe 2 access control mechanisms and consider whether they can be used in the organization. Describe single sign-on (SSO) and virtual private network (VPN) technology and whether they can be used in the company.

In this module, you learned about how an OS can exist on a virtual machine. For example, you might use a MacBook and have macOS Catalina as the operating system installed on it. Then you might use Windows 10 as a virtual desktop on a virtual machine. This capability allows you to utilize both OSes on one computer. As you complete this module’s discussion, you and your peers will reflect on the value of virtualization, specifically in relation to operating systems.
In your initial post, address the following:
Provide an example of when an organization or an IT professional might choose to implement an operating system via virtualization, and explain how that example meets organizational needs.
In response to two of your peers, address the following:
If you agree, build upon the original poster’s claims and further the discussion. If you disagree, state your own argument in a constructive way.
Then answer the following questions:
Why is virtualization important, especially in relation to OSes? What makes virtualization important?
How is virtualization being used in the workplace today?
FOR OTHER FRIENDS REPLIES
1. There are many instances, within organizations, that call for using virtualization. One example would be two organizations collaborating, however, one organization (we’ll call them organization B) still uses legacy software that is specific to their older OS. Organization A could revert all their systems back to that version but the expense and practicality of it would be a nightmare to execute. Instead, organization A can simply use a virtualization machine that is based in a main computer or server and has instances set up across the organization where it is needed. The reason for having a VM set up on main server or computer is so that you only need one firewall to regulate all the packets to and from the VM. Then you set up a internal VM network on all company computers and run those instances through the firewall VM which is external (allows for internet connection).
This solution will allow organization A to use organization B’s legacy software without great expense or technical headaches. Ultimately leading to a successful, and ideally profitable, collaboration.
2. Imagine a situation where a company needs to run multiple operating systems on the same physical server for different purposes. By using virtualization, they can create multiple virtual machines (VMs) on a single physical server, each running its operating system.
This fulfills organizational needs in several ways:
1. **Resource Efficiency**: Virtualization allows better use of hardware resources by consolidating resources and reducing hardware costs and energy consumption.
2. **Isolation**: Each VM operates independently, enhancing system reliability and stability.
3. **Flexibility**: Virtualization offers the flexibility to quickly deploy and scale environments as needed.
4. **Security**: Virtualization can enhance security by isolating sensitive applications or environments.
Overall, implementing operating systems via virtualization allows organizations to optimize resource usage, increase flexibility, improve security, and streamline IT management processes, effectively meeting various organizational needs.

IT543-4: Design an implementation of cryptographic methods for an organization.
Assignment Instructions:
This assignment requires you to analyze a system, identify the cryptographic requirements, and then design a set of solutions to secure the data and the communication within the system. The system to be developed is based on the following scenario:
The ACME Yearbook Company has an existing desktop application that allows customers to create school yearbooks. The desktop application imports a portrait template containing a text document with student and faculty names, grades, and filenames. The filenames identify the yearbook photo for the respective individual. The application then allows the customer to edit the portrait database and design the school’s yearbook, including the ability to import additional photographs and lay out each yearbook page. When the yearbook is completed, the application uploads a data set to the portrait database “in the cloud” and all of the layout data for each yearbook page.
Note: Their previous product used CD ROMSs, and there was no Internet access for development, viewing, or purchase.
The company uses this data set to produce a high-resolution PDF of the yearbook, which is then used to produce the printed hardcopy yearbooks for the school. Additionally, the schools can request electronic copies of the yearbook on CDs for record-keeping or for direct sale to students to accompany their hard copies.
The ACME Yearbook Company has hired you to help them develop an Internet-based product to complement the existing desktop application. Write a report to the company explaining what features need to be added to their product to make it secure.
The Internet-based product should include the following additional features:
Allow all yearbook data to be stored on ACME’s servers, rather than on the customer’s local computer.
Allow the desktop product to be used to edit the yearbook and any new Internet version of the product.
Allow multiple people to edit the yearbook at the same time (including any students who are working on the yearbook).
Allow people to purchase copies of the completed yearbook using a credit card.
Allow a low-resolution PDF of the completed yearbook to be available to the school for proofing. Also, make available a high-resolution PDF that can only be accessed by ACME’s printing facilities and partners.
Security concerns include:
Licensing of the application client on school PCs.
Security for the output designs on the cloud and on CDs.
Secure storage of multiple yearbooks from multiple clients at ACME and in the cloud.
Online purchasing of electronic copies of yearbooks.
Communications security.
You must do the following:
Identify and list RISKS to be addressed.
Design a solution or a solution set.
You do not have to address all of the items below, but here are some possible topics to consider:
Email
Remote access (VPN)
Whole disk encryption
Encrypted flash sticks
E-commerce transactions
Database encryption
Use of hashes (e.g., for checksums, passwords, perhaps even credit card information)
Cloud access security
Digital certificates (at various levels)
DRM for electronic copies of yearbooks
Acceptable use policies regarding the use of company computers, personal computers, and perhaps even use of personal encryption
Identify potential vulnerabilities with your proposed solution. (Note: Not all vulnerabilities can be solved with encryption.)
Finally, in case the company cannot implement all of your suggestions at once, list the features that you recommend and rank order them by importance.
Your design should take into consideration the data storage, data processing, and data communication needs of the system.
It is anticipated that the length of the paper will be 10–12 pages.
Your job is to:
1) implement the one algorithm in these files that is not already implemented (merge sort),
2) Tell me in a comment in your code three things:
what the runtime of this algorithm is
whether it is “destructive”
whether it is “in-place”
3) submit timing data along with your code to show that your code actually has the runtime you claim it does.
Your submission will be:
– A zipped copy of all the files I’m providing, with the unimplemented algorithm implemented and the comments attached to taht algorithm indicating its properties (see above).
– And, in your zip file, you should include some kind of graph showing the growth of the runtime of your implementation of the algorithm, as determined by running it under different conditions and timing it, along with the raw timing data you used to make the graph.You can make the graph however you like (hand-drawn is fine).
