Note: Need Original Work as the paper will be checked via turnitin. I have added last week work as well which was done by youAssignment 5 –Application Classes and ArchitecturePurposeThe purpose of this assignment is to begin the design modeling for our ITOT Case Study. For this assignment, you will develop an application class diagram that includes entity, view, and controller classes as well as an architecture diagram.In this assignment we will begin the design for the case study, the IT Online Training Project. You have already completed sample analysis specifications for this case study. This assignment is based on the IT Online Training Project Requirements 2018R2. In this assignment you will develop an application class diagram and the software architecture for the application. The software architecture is usually developed at the very beginning of analysis and design, is continually updated, and is the guiding document for the design of the application.You will use the new Design Specification Template 2018 document to create your design specifications. Make certain that you keep the formatting and numbering of the template for your assignments. The Design Specification Template is a Word file with predefined sections that you will complete each week as you did with the Analysis Specification. In this assignment you will create an application class diagram for your detailed use case and you will also create a system architecture for your application.In this assignment you will complete the following sections of your Design Specification: 1, 1.1, 1.2, 1.3 Introduction to the Project 2, 2.1, 2.2, 2.3, 2.3 System Architecture Diagram for Case Study 3, 3, 3.1, 3.2, 3.3, 3.4, 3.5 4+1 Architecture 4, 4.1, 4.2 Application Class DiagramInstructions1. Review the IT Online Training Project Requirements 2018R2 and your previous submission for the project.2. Review the Quick Resources listed at the end of this assignment and the resources for Week 4..3. Open the Design Specification Template 2018 and save it as ENTD321Assignment5_FirstNameLastName.4. Sections 1, 1.1, 1.2, and 1.3. Complete Sections 1, 1.1, 1.2, and 1.3 of the Design Specification. These are just introductory comments. You can use the Analysis and Requirements Specification documents as references.Application Class Diagram5. Sections 4, 4.1, 4.2. Develop an application class diagram that includes entity classes (domain classes), view (boundary) classes like screens and forms, and controller classes that mediate between the view classes and model classes.5.1 Use your detailed use case (Manage Shopping Cart) as the basis as well as your sequence diagram. Review other use cases to make certain that the application class diagram supports the use case functions. Usually we start with one controller for each use case and name it using the name of the use case and the word "Controller".5.2 So for application class diagram start with a controller named after your detailed use case. Use your CASE tool to create the application class diagram. Add text that includes your name and course number directly on the diagram.5.3 Add view classes for the forms you identified for your detailed use case in your analysis specification. 5.4 Use your sequence diagram for your detailed use case and add the objects as classed to your application class diagram.5.5 Include a discussion of your application class model and how it works. 5.6 Insert your application class diagram into Section 4.1 of your design specification. Complete Sections 4 and 4.2 (discussion) of your design specification.System Architecture Diagram6. Sections 2, 2.1, 2.2, .2.3. Develop a System Architecture diagram for your IT Online Training application and include a discussion of the 4+1 architecture. Use some of the Microsoft suggested techniques or the web application techniques and present your architecture. I suggest that you might want to look at the Microsoft generic MVC architecture discussed in Lesson 5 and the Web Architecture article at the end of this assignment.6.1 Use your CASE or other tool and create an architecture diagram for the IT Online Training application. Insert it into Section 2.3 of your design specification. Complete Sections 2 (introduction to contents of section), 2.1 (assumptions and dependencies), 2.2 (general constraints), and 2.3.1 (discussion) of your specification.7.

This term paper involves putting together the various concepts learned throughout this course. You are tasked with designing the most secure network possible, keeping in mind your goal of supporting three (3) IT services: email, file transfer (centralized), and VPN. Your first step is to design a single network capable of supporting there three (3) different services. Once you have fully designed your network, you will need to provide three (3) workflow diagrams explaining how your designed network handles the three (3) different transactions. The first is an internal user sending an email using his / her corporate email address to a user on the Yahoo domain with an arbitrary address of user534@yahoo.com. The second workflow diagram should show a user initiating an FTP session from inside your network to the arbitrary site of ftp.netneering.com. The third workflow is an externally located employee initiating a VPN session to corporate in order to access files on the Windows desktop computer, DT-Corp534-HellenS, at work. Write a ten to fifteen (10-15) page paper in which you complete the following three (3) Parts. Note: Please use the following page breakdown to complete your assignment: Overall network diagram: One (1) page Datapath diagrams: Three (3) pages (one for each diagram) Write-up: six to ten (6-10) pages Part 1 1a.Using Microsoft Visio or its open source alternative, create a diagram showing the overall network you’ve designed from the user or endpoint device to the Internet cloud, and everything in between, in which you: Follow the access, core, distribution layer model. Include at a minimum: Authentication server (i.e. Microsoft Active Directory) Routers Switches (and / or hubs) Local users Remote users Workstations Files share (i.e. CIFS) Mail server Web servers (both internal and external) Firewalls Internet cloud Web proxy Email proxy FTP server (for internal-to-external transport) Explain each network device’s function and your specific configuration of each networking device. Design and label the bandwidth availability or capacity for each wired connection.Part 2 Using Microsoft Visio or its open source alternative, create a Datapath Diagram for the following scenario: Local user sends email to a Yahoo recipient. Local (corporate) user having email address jonny.hill@Corp534.com sends an email to user534@yahoo.com. Document and label the diagram showing protocols and path of the data flow as data traverses through your network from source to destination. Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5, 6, and 7 (OSI) protocols that are used for each flow. Show user authentication when necessary. Using Microsoft Visio or its open source alternative, create a Datapath Diagram for the following scenario: Local user, Jonny Hill, transfers file using ftp through the Internet to another company’s site (ftp.netneering.com). He has to access the secure shell using his active directory credentials to authenticate to the ftp server (linux running Redhat) on the DMZ. He needs to transfer files from his desktop across the Internet to ftp.netneering.com. Document and label the diagram showing protocols and path of the data flow as data traverses through your network from source to destination. Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5, 6, and 7 (OSI) protocols that are used for each flow. Show user authentication when necessary. Using Microsoft Visio or its open source alternative, create a Datapath Diagram for the following scenario: Remote user, Hellen Stover, connects via VPN from home through the Internet to her corporate desktop, DT-Corp534-HellenS. Hellen uses a browser to initiate her VPN connection. By browsing to https://VPNaccess.corp534.com, she arrives at a login page where she needs to authenticate using her Active Directory credentials before the VPN tunnel is built. Document and label the diagram showing protocols and path of the data flow as data traverses through your network from source to destination.Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5, 6, and 7 (OSI) protocols that are used for each flow.Show user authentication when necessary. Explain how your overall design protects the organization from both inside and outside attacks. Give examples.Explain how your layered design compensates for possible device failures or breaches in network security. Determine whether any possible bottlenecks exist in your design.Explain how to make the file transfer process more secure.Part 3 Use at least three (3) quality resources in this assignment.
