Compare and contrast two layers of the Open Systems Interconnection (OSI) Reference Model, including the protocols that run on each layer.
All posts must be a minimum of 250 words. APA reference. 100% original work. no plagiarism. The Reference Model is a conceptual framework for understanding how computers communicate. The OSI model defines seven different layers of communication rules. Each layer of the OSI model has its own means of communication or protocol. The OSI model is used as a reference when explaining how data passed over the network moves through each layer. Each of the seven layers has specific responsibilities and logically interfaces to the layer above or below it. Each layer in the OSI model provides a different service needed for communication across an IP network and physical media. The top three layers often are called the “upper layers” since they deal primarily with application data. The lower layers deal primarily with getting packets to their destination. Many refer to these layers as infrastructure. Questions:1. For this discussion, compare and contrast two layers of the Open Systems Interconnection (OSI) Reference Model, including the protocols that run on each layer.2. What was the reason that IPv6 was introduced? Why do you think many organizations are not upgrading their network solely to IPv6 and run that protocol instead of running IPv4? 3. What is the purpose of subnetting when using IPv4 addressing? What role does subnet mask play in subnetting of IPv4?
What effect does the product placement have on the sales?
A popular consumer staple was displayed in different locations in the same aisle of a grocery store to determine what, if any, effect different placement might have on its sales. The product was placed at one of three heights on the aisle – low, medium, and high – and at one of three locations in the store – at the front of the store, at the middle of the store, and at the rear of the store. The number of units sold of the product at various height and distance combinations was recorded each week for five weeks, and the following results were obtained: What effect does the product placement have on the sales? For this you should: i) Analyze the data with an analysis of variance. Perform all the necessary tests (including testing for treatment means, interaction and, if necessary, for main effects), and state the hypotheses and conclusions for all of them. When testing for interaction, make sure you explain precisely what interaction means in the context of this problem. ii) Produce a profile plot of the mean number of items sold. Comment on this and relate it to your tests. iii) Perform any relevant comparison of means procedures. iv) State your recommendations on where the product should be placed.

Project Description The purpose of project is to write an executive proposal for a fictitious company called Advanced Research Corporation. The goal of the proposal is to persuade the executive management team to approve the purchase of a security testing software that can benefit the company’s corporate network security by testing and identifying vulnerabilities before they are exploited by hackers. The proposal must include a detailed description of the software, its purpose and benefits. Company Description Advanced Research Corporation Advanced Research is a startup medical research and development company. After five years of extraordinary success in the development of innovative medical and pharmaceutical products, Advanced Research is on its way to becoming a major player in the medical research and development industry. However, due to its success, Advanced Research has also become a major target of cybercriminals. Advanced Research has been the victim of cybercriminal attempts to steal intellectual property and sell it to Advanced Research’s competitors. It is suspected that the corporate network has been infiltrated from unauthorized sources more than once. In 2011, Advanced Research was falsely accused of unethical research and development practices. The false allegations resulted in the defacement of Advanced Research’s public website and several Denial of Service attacks at different times over a 9 month period that brought the corporate network to its knees. These attacks had a major impact on Advanced Research’s ability to conduct business and resulted in undesirable publicity for the company. Regardless of its security problems, Advanced Research has continued to grow as a company. Its research and development departments have grown over the years, due to the expansion of the company, in proportion to the increase in its business making up over 40% of the human resources. Advanced Research’s innovative research and development information is paramount to its continued success as a company. Although, no known attacks have occurred in last 18 months, the security of its network and intellectual property is still a major concern for the company. Because Advanced Research is a still fairly young company, management has been hesitant to budget for expensive security projects. However, this point of view is beginning to change. Particularly, because one of Advanced Research’s competitors, a major player in the medical research and development industry for over 40 years, experienced a loss of hundreds of millions of dollars in research data that was stolen from its corporate network by cyber thieves. Background and your role You are the IT Manager hired in 2012 to manage the physical and operational security of Advanced Research’s corporate information system. You understand information security issues better than anyone else in the company. You also know that the network is vulnerable to outside threats because it has experienced attacks in the past and because you haven’t had the resources to properly test the corporate information system to identify the vulnerabilities that might exist and take action prevent possible attacks. You have a responsibility to bring these concerns to the attention of the executive team and ask for approval to purchase the necessary testing software. Your education and training have introduced you to variety of security tools for testing computer and network security. The majority of these tools you either only read about or have practiced using in lab environment. You have decided to research some of these tools and test them out in your own lab environment and choose one for recommendation to executive team. You will need to present information that proves the chosen tool will be beneficial to the security of corporate information system. To accomplish this you will need to research the product, if possible, test the product in a virtual lab environment. If the tool is part of your iLab exercise, it is recommended that you practice using and testing the tool beyond the scope of the lab exercise. Based on your research and analysis, you will include this information in your proposal in way that the executive staff can understand and allowing them to make an informed decision to approve purchase of the product. The executive management team of Advanced Research: The software should test for one or more of the following types of attacks: Choose one or more tools to use in this scenario from the list of available security tools: Corporate Office Network Topology The Advanced Research main research and development facility is located in Reston Virginia. You have concerns about the sensitive information that is stored at this location as well as data that transmitted over the WAN to Advanced Research’s New York City headquarters location, business partners and clients. The Reston facility is also where the Advanced Research data center is located. The data center is where Advanced Research’s public website, email, databases and corporate intranet are hosted. The environment contains a mix of Microsoft and *NIX technologies.· 45 Windows 2008 Servers· 13 Windows 2003 Servers· 15 UNIX Servers· 2200 Windows XP and 7 Desktops· Web Servers: Apache and IIS· Services: FTP, SMTP, DNS, DHCP, VPN· Database: SQL, Oracle and MySQL· Network: Cisco Routers and Firewalls
