Need 3 pages with peer-reviewed citations. No introduction or conclusion required.

Since it is so dangerous, why would designers install software into the kernel at all (or make use of kernel software)? If you were an antivirus designer or maker, what other methods do you utilize to prevent viruses?
Answer the questions with an APA-formatted paper (Title page, body, and references only).  Your response should have a minimum of 500 words.  Count the words only in the body of your response, not the references.  A table of contents and abstract are not required.

One of the big challenges with cloud-based reputation checks is performance. Users do not typically want to wait a few seconds while the reputation of potential URLs is checked. Most of us have come to expect that websites are at the immediate tips of our fingers and that access and loading of the content should take place rapidly and immediately. This presents a tricky security problem. Since the reputation service exists in the cloud, the challenge can be summed up as, “How can a reputation be securely retrieved without slowing Web access down so much as to create a poor user experience?”
Answer the questions with an APA-formatted paper (Title page, body and references only).  Your response should have a minimum of 500 words.

Overview
Throughout this course, you will be completing several labs. These labs have two purposes:
To provide you with valuable opportunities to “walk a mile in the shoes” of a forensic practitioner performing basic forensic tasks (Gaining this type of experience is necessary for managing and relating to the individuals and teams you will interact with in the field.)
To help you practice the communication and writing skills you will need to employ in both pieces of your final project
It is important to note that these activities are relevant to your final project. They are practice opportunities that focus on some of the specific topics and skills that need to be addressed in the network defense training manual you will create, and the milestones you will complete in modules throughout the course. It is expected that examples and details from your experiences with the labs will support the sections in your training manual.
Required Screenshots: In your lab report submission, be sure to include the screenshots outlined in the IT 643 Course Lab Guidelines document. Screenshots need to display your name and the date within the image. Follow these steps to complete the screenshot:
How to Take a Screenshot (in Windows)
Open Notepad and type your name and the date.
Place the Notepad screen next to the InfoSec lab you are completing.
Hit the Control and Print Screen keys together (Ctrl + PrtScr).
Open a Microsoft Word document and paste the screenshot.
When you have finished pasting screenshots, upload the entire Word document to your assignment.
What to Submit
For each lab assignment, follow the instructions provided in the prompt. Each lab assignment should be submitted as a Microsoft Word document with the required screenshots. Any sources must be cited according to APA style.

ASSIGNMENT 1:
In this journal reflection, you will answer the questions below to help you formulate your topic. 
Please address the following in your journal:
Identify a      topic in your specialization. (For IT students, Information Technology is      not a topic, however, Millennial’s perceptions of smart phone technology      could be a topic.  For leadership students, leadership or leadership      styles would be too broad.  You could, however, compare leader and      followers perceptions of leadership styles in private four year      institutions. These are examples).  
What is the      current problem related to your topic? Who is the problem happening to?      Where is the problem happening? Provide at least two citations to show      that the problem is still happening today. 
What part of      the problem listed in #2 do you want to research and why? 
What      methodology are you planning on using? (If you are unsure, do you plan on      a quantitative or qualitative study?  You will determine your      methodology in 839).
For the      methodology listed in #4, how and where will you get your data? 
What theories      or frameworks (i.e. transformational leadership theory, technology      acceptance model, etc) will guide your study? What are the origins of      these theories? 
Share your topic idea(s) by going to the “Week 1 Assignment – Journal Reflection on Topic Ideas” link above.

  
2.2 – Week 2 – Dissertation Summary
Overview: Using mentor or model texts is a strategy to improve your own writing.  The New York Times describes mentor texts as, “Demystifying the writing process via examples students can learn from and emulate.” In this assignment, you will locate a mentor text in the form of a dissertation that may or may not be similar to your own topic to use as a model while you write your chapter 2.  It is most helpful to find a dissertation with a literature review similar to your own, but if that is not possible, you may look for the next best option. 
Directions:
Use ProQuest Dissertations &      Theses Global database on the UC Library website to locate mentor text      dissertation (preferably it would be related to your topic). 
You may need to use advanced      search options to help narrow your search. 
Scan read the entire      dissertation.
Carefully read the      literature review section.
Provide a      one-paragraph summary of the entire literature review.  
Write a second      paragraph about what you learned through reviewing chapter 2. 
Additional Information:
ProQuest Dissertations & Theses Global database is accessible through the Databases link below the blue picture on the Library website. The Databases tab will access an alphabetical list of the Library databases. The dissertation database is listed twice, as Dissertations and Theses and as ProQuest Dissertations and Theses. Both links access the same database. Many of the dissertations published since 1997 are available in full text with a link to the PDF.
