Discussion 66

 

Murder Case

Preamble

An organization system administrator was labeled as the key suspect in a homicide case. The accused claimed that he was at work at the time of the murder. 

Police Intervention

The police asked his employer to help them verify his alibi. Unpredictably, the same organization, occasionally trained law enforcement personnel to investigate computer crimes and was eager to help in the investigation. 

Collaborative Strength: 

The organization worked with police to assemble an investigative team, seized the suspect computers in his office and residence, and backup tapes on a file server managed by his employer. All of these evidence were stored in a room to where only members of the team had access. 

Harsh Situation

At the initial stages, the operation appeared reasonably well documented, but the reconstruction process was a disaster. The investigators made so many omissions and mistakes that one computer expert when reading the investigator’s logs, suggested that the fundamental mistake was that the investigators locked all of the smart people out of the room. The investigators, in this case, were unaware of the situation and unwilling to admit the slip-up.

As a result of the investigators’ omissions and mistakes, the suspect’s alibi could not work together. Digital evidence to support the suspect’s alibi was identify later but not by the investigators. If the investigators had sought expert assistance to deal with a large amount of digital evidence, they might have quickly confirmed the suspect’s alibi rather than putting him through years of investigation and leaving the murderer to go free.

Lesson Learned

  • The case amplifies forensic investigators’ requirements to obtain fundamental knowledge of computers, compatible operating systems, and application software programs.
  • Forewarning forensic investigators to seek the assistance of the system administrator during the criminal investigation. 

Scenario 

  • You have been retained as a Deputy Technology officer at the University and charged with the responsibility of developing an Acceptable User Policy for the department of computer science based on this murder case.
  • Question 1
  • Use the AUP to amplify the advantages and disadvantages of investigators’ quarterly training on most currently used operating systems such as Microsoft Windows, Macintosh, UNIX, Linux, Sun System, and more. 

Scenario 2

  • The investigators, in this case, were unaware of the situation and unwilling to admit the slip-up. As a result of such omissions and mistakes, the suspect’s alibi could not work together. Digital evidence to support the suspect’s alibi was identify later but not by the investigators. If the investigators had sought expert assistance to deal with a large amount of digital evidence, they might have quickly confirmed the suspect’s alibi rather than putting him through years of investigation and leaving the murderer to go free.
  • Question 2 “Investigators allowed the Murderer to go free.”

2:1. Defend the impasse of the investigator’s unwillingness to admit the slip-up?

2:2 Use the Acceptable User Policy to amplify why the murderer was allowed to go free and penalties for violations.

Network Management

Instructions:

Part one:
–Create a network drawing for a mock company that has two sites in different geographic locations (at least 40 miles apart).

—One site must have at least one server.

—Appropriate cabling and connectivity between the two sites.

—Labeling to make the drawing professional.

–In a minimum of two paragraphs, describe the mock company, the networks, and type of connectivity to the other site, as well as the Internet that is in your drawing. Describe the network components that will be monitored and/or managed using an NMS(Network Management System).

Part Two:

-The minimum requirements are as follows:

—An executive summary of the implementation plan

—Professionally formatted comparison table of NMS products you considered including costs and features (you may have a bit of a time getting cost, but try or estimate and ensure you note if it is an estimation)

Linux Implementation Proposal: Training Guide

 

Linux Implementation Proposal: Training Guide

Hide Assignment InformationTurnitin®Turnitin® enabledThis assignment will be submitted to Turnitin®.Instructions

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.

How Will My Work Be Evaluated?

In this training guide, you will demonstrate how to install Linux and provide an overview of common commands for your client/customer. You’ll be combining your technical skills with effective communication techniques to provide learning resources for the client/customer.

The following evaluation criteria aligned to the competencies will be used to grade your assignment:

  • 1.1.4: Explain the relationship between the ideas presented to enhance clarity and comprehension. 
  • 1.2.2: Employ a format, style, and tone appropriate to the audience, context, and goal.
