For this assignment, you will identify a computer system you have recently had experience with and prepare and attach a PowerPoint presentation (8-10 slides) describing a potential computer security problem related to that system. The target audience is a manager who you are trying to convince to initiate a project to investigate the potential security issues.

Suggestions:

• Begin with an description of the organization and the computer system you have chosen.
• Where necessary, you may make assumptions about any specifics–please note these as such in your presentation notes.
• Draw from the assigned readings (and independent research) to identify what topics should be included.
• If you feel that slide information is not self-explanatory, add additional details in the presentation notes.

See assignment 10-45 

Provide the answers to all the descriptive statistics, stated in the problem.  

Correct output is required.  Also, presenting the work in a very professional and visually appealing manner is required to get full credit.  

Do Not send the final results in a protected view.

Make sure your formulas are included in the worksheet,  This allows me to change the numbers and confirm that the new answer is calculated correctly.

 10-45. Because of the employees’ increased use of IS resources for private purposes at Campus Travel, you have announced that a new acceptable use policy will be implemented. You have set up a website for the employees to provide feedback to the proposed changes; the results of this survey are stored in the file EthicsSurvey.csv. Your boss wants to use the survey results to find out what the greatest concerns in terms of ethical implications are for the employees, so you are asked to do the following: 

■ Complete the spreadsheet to include descriptive statistics (mean, standard deviation, mode, minimum, maximum, and range) for each survey item. Use formulas to calculate all statistics for the responses to the individual questions.  (Hint: In Microsoft Excel, you can look up the necessary formulas in the category “Statistical”; you will have to calculate the ranges yourself.) 

■ Format the means using color scales to highlight the items needing attention.

 ■ Make sure to professionally format the pages before submitting them to your instructor. 

I have a computer information system assignment, I’m stress out with my finals and I really need t earn good grades for both my finals and this assignment I introduced to this web from one of my classmates hope someone can help me to succeed I’m good in computer but my instructor make everything a little bit complicated.  I attached all requirements. Due date November 21st.

Thank you 

 After reading Chapter 9 discuss how your employer prepares to establish, maintain, and execute your temporary work area to reestablish or maintain your business operations.  You can use information from your employer, outside research, or your personal work experiences as your basis for this discussion.

Description: The university maintains course schedules at http://appsprod.tamuc.edu/Schedule/Schedule.aspx for different semesters (spring, fall, winter, etc ). You will develop a Python program to dynamically complete certain tasks, such as list, find, sort, and save, in course listings from schedule portal. You will mainly use “request” and “BeautifulSoup” libraries (or similar, see exercise 12.1). The program will operate at different level: Semester and Department.  Your program will be a menu based application. Assume that you project file is myproject.py. Once you run, it will show last 5 semester (fall, spring, summer only, (not winter, may mini))

> python myproject.py
Choose a semester: 1) Sprint 2021   2)Fall 2020  3)Summer II  4)Summer I 5)Spring 2020 
Selection: 2

Here, your program will parse the data from website and show only last (most recent) 5 semesters. User will make selection, then, you will show departments for the selected semester (Fall 2020). Note that selected semester is visible before a “>” sign.

Fall 2020> Select a department:
1) Undeclared
2) Accounting and Finance
3) Art
4) Ag Science & Natural Resources

Fall 2020> Art > Select an option:
1) List courses by instruction name
2) List courses by capacity
3) List courses by enrollment size
4) List courses by course prefix
5) Save courses in a csv file
6) Search course by instruction name
7) Search courses by course prefix
Q)Go back
Selection: ??

Here, your program will parse the data from website and show all available department then list of tasks. Q (go back) option will take user to previous level. 

Course listing output should show the following fields. For instance for course listing for “Fall 2020> Computer Science & Info Sys> List the course by prefix ” should show

Please read the below discussion post and provide response in 75 to 100 words for each discussion post

Post#1

DAC is the way people can control their own content. This may sound obvious, but DAC, for example, is really useful for online users who have access to their information. It enables people to quickly and automatically remove or deny privileges. Reactive access control, More display and file sharing Laissez-faire provide users with good examples of DAC science.

A framework that uses DAC allows the resource owner to determine which subjects can access particular resources. This model is referred to as discretionary as access control is focused on the owner’s discretion. There is a different word, which is mostly used for modeling. This is the List of Access Control. A file ACL will list all licensed users and/or groups who have access and unique access to the file.

Although all in the DAC world seems fine, this model has some problems. While this model has the best versatility of any model, it is its weakest point. For instance, when a user opens a virus-infected attachment, code can be installed on the background without the user being conscious. In general, this code inherits all of the user’s rights and permissions and can perform all user-related operations on the device.

A user is only permitted in the system by placing them on the system-associated Access Control List ( ACL). You need to realize that an entry in the ACL of a resource is known as the ACE. For the test, research this. These permissions are activated when a user or group owns an object within the DAC model, and when the user group og allows other users and groups within the same structure. The DAC model is focused on ownership of resources, which is essential for the review.

RBAC is a form of access control that, as you said, is capable of separating responsibilities in a system that fulfills multiple roles. Obviously in companies (such as Brewer, Nash or MCS), this is true but can also be used in a single operating system to enforce the less privileged principle. By letting users choose the positions they need for a particular task, RBAC is optimized for separating tasks.

If a user is allocated a task by an administrator that includes some predetermined system rights and privileges, the player will be able to access only certain system resources and perform certain functions that have to be allocated under the rules. Please note that RBACK is also known as the Non Discretionary Access Control because it is necessary for the review. The user functions are handled centrally by the system administrator.

If your Customer Service Representative is calling the cable provider to collect your pay-per-view, I would say I am sorry that you have been sent to Billing so that you can pay your expired bill they know that you have an outstanding bill. You pay your bill and inform me that I will get my service when you are moved to the bill. I see you want this service but that isn’t my role. They say let me pass you back.

MAC itself is vague, for many systems there are various ways of implementing it. You will also use a mixture of multiple paradigms in operation. For example, most DACs are used by UNIX and DAC privileges are bypassed by the root account. In an organization you can allow some DAC for employees to exchange information about your corporate file system in addition to separating the various divisions and teams with the MAC / RBAC.

A construction of control is one of the main elements that only occurs in the MAC. No amount of approval will get you to see a Top Secret Document if you have secret level clearance. It’s unusual that you need this building in commercial organizations. However, the second point, which is special to MAC, is that if you can not do an operation, you can not do it in particular.

Post#2

In the technological organizations, it is the security which most of the organizations are looking to perform their operations. There are opportunities within the an organization which sometimes slip away due to security concerns and the threat possibilities therefore a robust framework is required to mitigate all the threats. An information a system which can help in the mitigation of threats and keeps check on confidential information of the organization. This can be ensured by the three types of models of security in cloud computing technology. These systems are well implemented and built to perform access control modes. These are MAC, DAC and RBAC. “To implement get to  control,  it  has  been  said  that  all  the  accompanying customary  models  can  be  utilized  as  a  part  of  distributed computing: required access control (MAC), optional access control (DAC) (for instance, get to control records or ACLs), and nondiscretionary get to control (for instance, RBAC or assignment based access control” (Niranjan, 2018).

MAC is the Mandatory Access Control which uses a combination of different paradigms to implement security in many systems. MAC is a vague access control model which allows some DAC for coworkers to share data and manage the corporate file systems in the organization. Security labels are assigned to resource objects within the system which contain information based on two pieces and classify the confidential information. User attempts to access resource under MAC is assessed with the security labels.

DAC is the discretionary access control which allows users to control and access their own information and data. This type of access control systems is used for the desktop operating systems. DAC is assigned a Access control list which contains information about the groups and users who has permitted the access and the level of access given in the system to the user of the group. There are control access systems which are utilized within the system to provide security to the organization. “The organizations are adapting to cloud networks at a rapid pace due to the benefits like cost-effectiveness, scalability, reliability and flexibility” (Indu, 2018).

RBAC is the role based access control which is based on the mechanism which is the job oriented function and places as the user within the organization. It is the computer system which belongs to the system access control and performs all the necessary actions. The RBAC access model is also known as the non discretionary access control. RBAC introduces the absurdness within the system which allows the user to set a number of rules which is defined within the system administrator. It is the system and the situation which is based on the network connection and also permits the user to a particular time frame. “As the number of roles increase, the complexity is increased. To get rid of limitations of RBAC, the attribute base access control model has been introduced which has more flexibility” (Soni, 2019).
