Discussion Question 1:Describe Group Policy object and why an organization would choose to deploy Group Policy. Explain some of the settings within Group Policy that organizations might choose to keep their desktops and servers secure.Discussion Question 2:You are an administrator for a large organization with a group of web developers that works on UNIX machines. You need to come with a solution that enables the web developers to save their files on the Windows system so that those files can be backed up with all of your other data. Because the web servers are critical to the company, you must ensure that the data is available and backed up regularly. Describe your proposed solution.

1) In a corporate, networked setting, should end users be allowed to install applications on their company workstations, whether the applications are on a DVD or downloaded from the Internet? Be sure to weigh security against usability. 2) For this assignment, you are asked to locate any company privacy policy. Some of the more popular ones might include GOOGLE, APPLE, or MICROSOFT, but you may elect to review another agency. In 3- 4 paragraphs, explain what you find to be the most interesting information contained in that privacy policy. At the end of your report, please include a LINK to the policy you have reviewed. 

1.) Think of a poorly designed interface and a well-designed technology interface from your personal life. What are the characteristics of each? 2.)What are the differences between SDLC and Agile methods?3.)The head nurse at Regions Hospital is expecting to implement a new human-technology interface system that will expedite admissions for patients arriving by ambulance. This technology will involve scanning the barcode on the patient’s driver’s license while at the scene and electronically sending the personal data to the receiving emergency department.  Choose a method to implement this technology. Write out the steps to successfully complete this implementation (what is needed? look at the phases of system life cycle). Include a swim lane diagram of the new process. 4.) Does the above scenario represent a simple or complex health care system?  Provide a rationale

To enhance the security of information systems, enterprises are developing and adopting information system management systems. However, if an information management system is exploited, applications and the data they contain will be compromised. Therefore, it is important to perform a comprehensive security analysis throughout the enterprise.In your own words explain (a) the purpose of an security analysis, and (b) using fig 2.2 (“Knowledge sets that feed a security analysis”) as a guide, in your own words briefly explain what each knowledge domain entails. Please state your answer in a 1-2 page paper in APA format.  Include citations and sources in APA style.

In this programming project, you will be writing sending and receiving data link layer code for implementing a simple reliable data transfer protocol. There are two versions of this project, the stop and wait for version and the GBN version.This project prototypes are protocol3 and protocol5 in chapter 3 the data link layer of the textbook. You should implement the function from_physical_layer() and to_physical_layer() using UDP socket API. You should also implement other functions to make protocol3 and protocol5 runnable. Sender must display variable next_frame_to_send, ack_expected, s.seq. Receiver must display variable frame_expected. Sender will send 9 frames every 10 frames to simulate frame lose.You must submit the following files:The project design document: for example, flow chart and running screen display.Source code and executable file

C I A triad Nonrepudiation is the ability to have proof that a message originated from a specific party. In an email system, for example, nonrepudiation mechanisms ensure that every message can be confirmed as coming from a specific party or sender.Answer the following question(s):Do you think nonrepudiation falls under one of the tenets of the C-I-A triad (confidentiality, integrity, and availability)? Why or why not?Is the C-I-A triad adequate when selecting controls for a Windows system? Why or why not?
