Imagine you are the CEO of a large technology company whose primary products include microprocessors and operating systems. You have three engineering departments. Each is headed by a passionate technologist in the role of chief engineer.
Here are their proposals for introducing the next “killer” product:
1. The chief of microprocessor engineering wants to introduce the next generation of the instruction set architecture (ISA). She wants to offer a new ISA that revolutionizes the instructions set the way RISC did to CISC.
2. The chief of motherboard engineering wants to make radical changes to the peripheral component interconnect (PCI) interface for hardware that will double PCI transfer speeds of the company’s motherboards without negatively impacting compatibility with the existing PCI standard. 
3.The chief of portability engineering wants to make the company’s portable operating system interface (POSIX) interface for system calls more compliant so that millions of Linux and Windows developers will have the same operating system interface.
In your initial post, describe which of these plans would you (as the CEO) approve and why? Be sure to justify your selection with technical details.

Introduction
The more preparation you put into the design of your database up front, the fewer problems you will run into in the future. You also will be able to build your database much quicker with this information planned out.
Directions
Build a data dictionary from your submitted datasets with the fields you plan to include in your database.
Your data dictionary should include:
Name of your database
Entity type
Attributes for each entity
Attribute data type
Required/optional attributes
Example of the attribute
Short description of data field
Will the field accept a NULL value?
Submit your file as an .xls file. If you used Google Sheets, export into .xls to upload.

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?

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.
