Question for Week7:

In week #4, your midterm project was to provide a security assessment for Vestige, Inc, an online software company that specialize in selling ad spaces in their parent company’s magazine.  Vestige manages an online database that allows their customers to upload and pay for their business ads for magazine placement.  Because Vestige’s database needs to connect to the parent company’s database, the parent company has requested that Vestige system be assessed and verified as secure.

Now that you have provided your security assessment, the next step is to provide Vestige, Inc. with your Security Portfolio. Using this week’s Reading on the NIST framework that includes the 5-step process for creating a balanced portfolio of security products, your assignment will be to create a Security Portfolio with the following sections:

1. Cover Page (i.e. APA title page)

2. Background (provide a synopsis your midterm security assessment on Vestige)

3. For each security need identified (or needs to be identified) from your Week #4’s Midterm Assignment, Find the products that will deliver the needed capabilities for the right price, and tell why you chose that product.

This assignment should be about the security needs only.  Do NOT discuss how the client can achieve more business (That is not your job). Please use  APA format and include at least two references.

What is the history of the network models? What are four layers of the TCP/IP Model and how are they used? How does the networking protocol work?

Search the peer-reviewed literature to identify its potential impact on networking and what measures can be put in place to minimize the effect.

1. Transient Overloads: One drawback of RM algorithm is that task priorities are defined by their periods. Sometimes, we must change the task priorities to ensure that all critical tasks get completed. With average execution times, all the critical and non-critical tasks may be RM-schedulable. But, if we consider worst-case execution time we wish to schedule so that all critical tasks meet the deadline and the non-critical task may miss the dead line. The solution is to boost the priority of some critical tasks higher than the non-critical tasks. This is done by altering the “Period” of some critical tasks so that their priorities increase. For example: If we reduce the period of a task by k and have k number of tasks each small sub task will have period divided by K, and execution time divided by k. When the period is smaller, the tasks automatically get higher priority. We can also lengthen the period of non-critical tasks and make it larger than the largest critical task and increase the non-critical task’s execution time also.Carry out a period transformation for this task set to ensure that all the critical tasks will meet the dead line even with worst case execution timing.
   Draw for your modified table of tasks, timing diagram to show schedulability for average execution time and another diagram to show for worst-case execution time. Identify if any tasks miss the dead line.
2. Give explanation of your period transformations and solution.
3. What is CPU Utilization for average and worst-case execution times.
4. Considering Context switch time to be 1 ms, redraw the execution time line for this system for both average and worst case timing.
5. What is the system time-loading (CPU utilization) factor with the context switching included?

Option 1: Research Report / Individual Project 

Write a scholarly research report on a topic related to Software Engineering (see Appropriate Topics). Please see Important Notes and Document Details for detailed specifications. 

Appropriate Topics:

The Research Report should consist of a comparative analysis of two programming languages of your choice.

You’ve won the business! Faster Computing has agreed to the project. As the final stage of pre-implementation, you have been asked to produce a training guide that will demonstrate how to install Linux and provide an overview of several common commands, as follows:

(11.1.3: Install the software.) 

• Use a hypervisor of your choice to install Linux. Many hypervisors are available, such as Oracle’s VirtualBox, which is a free download. In addition, as part of UMGC’s agreement with VMware, you can download VMware Workstation for free. See below for specific screenshot requirements. You should include at least 3 screenshots (e.g., disk partitioning, timezone selection, creating the default account). Each screenshot should be accompanied by a brief explanation of what you did.
  NOTE: It is not necessary to include screenshots of installing the hypervisor software.

(1.2.3: Explain specialized terms or concepts to facilitate audience comprehension.)

• Demonstrate command-line operations that will provide the following information:
  • A listing of files in a directory and common file attributes
  • The current directory (hint: also known as the present working directory)
  • Create a file, then copy it to a different directory
  • Create a second file and move it to a different directory
  • Remove the first file, as well as the copy you created
  • The manual page for a given command
  • Create a text file, then use an editor to modify the content. Then display the content of the modified file

(1.4.2: Use vocabulary appropriate for the discipline, genre, and intended audience.)

In the above section (demonstrate CLI operations) show the commands with options/arguments (e.g., ls, cp, mv, rm) in your documentation as well as in your screenshots. 

(11.2.1: Configure technology according to stakeholder specifications and requirements.)

• Show running processes on the system. Demonstrate how to search for a specific process
• Forcibly stop a running process

In the above section (demonstrate CLI operations) show the commands with options/arguments (e.g., top, kill, -9, ps) in your documentation as well as in your screenshots. 

(13.1.1: Create documentation appropriate to the stakeholder.)

The deliverable for the final phase of the project is a written paper with screenshots. There is no minimum or maximum page requirement, but all of the requirements must be met.  Use the Training Guide Template to record your work. This section will be graded upon the overall usefulness of the training guide to the organization.

(11.3.1: Add and update systems as required.) 

This portion of the training guide helps determine your submission is unique.

Important Requirement

On the final screenshot, you need to open a command line and type in the following commands (without the quotes):

“date”

“echo CMIT391”

“echo ” (Replace your name here with your name)

The recommended format is to provide screenshots incorporated within the written narrative. The screenshots must all be your own. Screenshots from external sources are not permitted. You must include the specific screenshot listed above or your project will not be accepted.

(1.1.4: Explain the relationship between the ideas presented to enhance clarity and comprehension.)

The training guide must have a cover page, an introduction, summary, and at least 3-5 references.

(1.2.2: Employ a format, style, and tone appropriate to the audience, context, and goal.)

Employ proper spelling and grammar. All Linux commands must be lower case.

(2.2.3: Explain the assumptions underlying viewpoints, solutions, or conclusions.)

In your conclusion of at least a paragraph, summarize why using Linux is beneficial for employees, management, and the organization as a whole.

1. Discuss the key components of human resource management.  Pick at least four concepts from chapter nine and describe how these concepts interrelate to individual performance on a team.

2. Review table 9.2 and select one of the dimensions listed, note why it was chosen and how you relate to this behavior.  If you have a personal experience, please share.

3. How do leaders select the best talent? What are some tools they can use to select the best-talent?
