Purpose

This discussion activity gives you the opportunity to solve a real world scenario. In doing so, you will learn the concepts of a software development cycle.

Directions

Part I: Complete Your Original Response to the Main Topic

You are a software developer for a Retail Point of Sale System Company. A client has made a request to upgrade the current system from command line interface to a graphic user interface. The client concerns on an effect to the current system with the change. The client does not want to lose any current data on the system. Provide recommendations and the change plan including the below requirements to the customer.

Requirements:

• Create a requirement plan (what need to be done to support this upgrade)
• Create a development plan (how to implement this upgrade with programming details explanation including technical details on this document)
• Create testing plan (how to ensure that the new upgrade works without affecting current system and no data lost.)

Posting your recommendations and the change plan

Once you have completed your recommendations and plan. Post it in the discussion forum by clicking the Reply link below.

• In the first line of your post, your should add your plan title and name.
• Your posting must include recommendations, a requirement plan, a development plan, and a testing plan.  

IN 250-300 words.  what a rootkit is ?

The readings this week discusses broad context of risk and investigative forensics. Part of risk management is to understand when things go wrong, we need to be able to investigate and report our findings to management. Using this research, or other research you have uncovered discuss in detail how risk and investigate techniques could work to help the organization. ERM helps to protect an organization before an attack, where as forensics investigate technique will help us after an attack – so lets discus both this week.

Please make your initial post should have 500 words and the post will do at least TWO of the following:

• Explain, define, or analyze the topic in detail
• Share an applicable personal experience
• Provide an outside source (for example, an article from the UC Library) that applies to the topic, along with additional information about the topic or the source (please cite properly in APA)

At least one scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.

1.) In no less than 250 words, describe the difference between a fat AP and a thin AP.  What is needed to deploy a thin AP?  Are there any security considerations to think about between the 2 different APs?  Respond to two other learners by the end of the week.

2.)  Have you or someone you know ever received a chain letter, phishing message, or some other fraudulent message via email? If so, please share this experience. Explain what type of message it was and what you did to get rid of it.

3.) Answer the below questions 

1 What is the basic building block of an 802.11 WLAN?

2 Define an extended service set.

3 List and briefly define IEEE 802.11 services.

4 Is a distribution system a wireless network?

5 How is the concept of an association related to that of mobility?

1.     

In this chapter we have looked at the point location problem with pre- processing. We have not looked at the single shot problem, where the subdivision and the query point are given at the same time, and we have no special preprocessing to speed up the searches. In this exercise and some of the following ones, we have a look at such problems. 

Given a simple polygon P with n vertices and a query point q, here is an algorithm to determine whether q lies in P. Consider the ray ρ := {(qx +λ,qy) : λ > 0} (this is the horizontal ray starting in q and going rightwards). Determine for every edge e of P whether it intersects ρ. If the number of intersecting edges is odd, then q ∈ P, otherwise q à∈ P. 

Prove that this algorithm is correct, and explain how to deal with degen- erate cases. (One degenerate case is when ρ intersects an endpoint of an edge. Are there other special cases?) What is the running time of the algorithm? 

2. Suppose you are given an n-vertex simple polygon, P. Describe how to build an efficient data structure for determining in O(log n) time whether a query point, q, is inside of P or not. What is the space and preprocessing time for your data structure?

3. The ray shooting problem occurs in computer graphics (see Chapter 8). A 2-dimensional version can be given as follows: Store a set S of n non-crossing line segments such that one can quickly answer queries of the type: “Given a query ray ρ—a ray is a half-line starting at some point—find the first segment in S intersected by ρ.” (We leave it to you to define the behavior for degenerate cases.) In this exercise, we look at vertical ray shooting, where the query ray must be a vertical ray pointing upwards. Only the starting point need be specified in such a query. Give a data structure for the vertical ray shooting problem for a set S of n non-crossing line segments in general position. Bound the query time and storage requirement of your data structure. What is the preprocessing time?

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. Evaluate the system engineering process from a design methods perspective and investigate Model-Based System Engineering (MBSE) used in your company.
2. Examine the requirements for system engineering program planning in the system engineering management plan (SEMP)
