Vulnerabilities of Embedded Operating Systems It is important to understand the different types of attacks that can occur depending on both the operation system and underlying hardware in order to properly provide effective local-oriented cybersecurity defensive strategies.
Vulnerabilities of Embedded Operating Systems
Create a 10- to 15-slide presentation that outlines the vulnerabilities of embedded operating systems, such as, but not limited to, IoT devices, programmable logic devices, and vehicle control systems. Address the following within the presentation:
Discuss the tools used by hackers to penetrate these devices and the effects of each penetration type.
Provide insight as to how embedded operating system vendors provide defenses against hacking attempts.
Describe, in steps, at least one strategy used to attack embedded operating systems.
Describe, in steps, at least one strategy used to defend against the chosen attack.
Explain ways in which you feel the programmers of embedded operating systems can improve on their existing attempts to secure the devices which host their programs.

As its name implies the article talks about how to install or replace a case fan in your PC. It talks about identifying faulty fans, what you need to know before installing a fan, choosing the right fan, among other things, before explaining how to install/replace the fan.
These instructions are okay, but definitely, have room for improvement.
How to Replace a Faulty Fan in PC Introduction Instructions
For this assignment, you will write a set of technical instructions on how to replace a faulty fan in a PC, based upon this article. Review the “Technical Instructions” slides from class, the additional help document available on Brightspace, as well as the textbook.
The technical instructions must tell the reader how to replace the case fan, not how to buy the new one.
Your audience is familiar with the appropriate tools but has never replaced a fan.
Create the first three sections of the document yourself (“Summary”, “Purpose”, and “Tools and Materials”). Pictures of the various materials/tools required are useful in the third section.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

1)Chapter 3 discusses methods to assess the quality of simulations. You learned about three different views of simulation quality.
Suppose you lead a task force that is developing a simulation to provide strategic planning recommendations for property use zoning for a county of 750,000 residents. The zoning board and county commissioners want a simulation that allows them to assess the impact of various zoning decisions based on a variety of dynamic factors, including age, race, education, and income status. Which of the three views discussed would provide the best quality assessment for this type of simulation? How would you ensure the highest level of accuracy with you simulation, and how would you go about determining accuracy?
You must do the following:
a) Create a new thread. As indicated above, identify which of the three views discussed in the chapter that would provide the best quality assessment for the situation described above, and explain your decision. How would you ensure the highest level of accuracy with your simulation, and how would you go about determining accuracy?
b) Select AT LEAST 3 other students’ threads and post substantive comments on those threads. Your comments should extend the conversation started with the thread.
2)Suppose you needed to replace 22 physical servers that are at end of life. You were trying to convince your boss that a cloud strategy is the best approach to replace the servers. Your boss is interested in your idea; however, he or she asked you to submit a business case.
To prepare for writing the business case, use this forum to discuss the following:
For your fourth programming assignment you will be writing the following C++ program: In a population, the birth rate is the percentage increase of the population due to births, and the death rate is the percentage decrease of the population due to deaths.
