Scenario

As a security administrator for Always Fresh, you have been instructed to ensure that Windows

authentication, networking, and data access are hardened. This will help to provide a high level of

security.

The following are issues to be addressed through hardening techniques:

▪ Previous attempts to protect user accounts have resulted in users writing long passwords down

and placing them near their workstations. Users should not write down passwords or create

passwords that attackers could easily guess, such as words founds in the dictionary.

▪ Every user, regardless of role, must have at least one unique user account. A user who operates

in multiple roles may have multiple unique user accounts. Users should use the account for its

intended role only.

▪ Anonymous users of the web server applications should only be able to access servers located in

the demilitarized zone (DMZ). No anonymous web application users should be able to access any

protected resources in the Always Fresh IT infrastructure.

▪ To protect servers from attack, each server should authenticate connections based on the source

computer and user.

Tasks

Create a summary report to management that describes a hardening technique that addresses each

issue listed above. Provide rationale for each selection.

1. The following must be submitted by the end of the Residency day (7:30pm ET) on Saturday. No credit is available for submissions not made by this time. The system will not accept submissions made after this time. This is not a group assignment, so no collaboration or discussion is allowed; it must be worked on individually. Submit your responses to all three questions in a single document. There should be a single title page for the document. However, each question should have its own separate references page (a source may be reused for multiple questions). The total length of the document should be between 13 and 16 pages. Do not include the wording of the questions in your paper.
   Question 1:
   In 750-1000 words, identify and explain the five steps of forecasting, and then come up with an original example taken from your own professional experiences to illustrate these steps. Your response must be original. You must incorporate at least three reliable sources, both as references and corresponding in-text citations. APA format is expected.

   Question 2:
   In 750-1000 words, explain qualitative and quantitative forecasting, and then come up with an original example of each taken from your own professional experiences to illustrate these two forecasting types. Your response must be original. You must incorporate at least three reliable sources, both as references and corresponding in-text citations. APA format is expected.

   Question 3:
   In 750-1000 words, identify and explain the types of data patterns, and then come up with an original example of each (strive to make it based on your own professional experiences) to illustrate each data pattern type. Your response must be original. You must incorporate at least three reliable sources, both as references and corresponding in-text citations. APA format is expected.

2. By submitting this paper, you agree: (1) that you are submitting your paper to be used and stored as part of the SafeAssign™ services in accordance with the Blackboard Privacy Policy; (2) that your institution may use your paper in accordance with your institution’s policies; and (3) that your use of SafeAssign will be without recourse against Blackboard Inc. and its affiliates.

Prepare  an 8 page APA style paper and at least 3 additional peer reviewed resources. Include an introduction and  conclusion in the paper. Remember to use APA formatted headings for each  section of the paper and provided in text citations of the sources you  use. This paper should address the following questions:

(1)  Does Blockchain technology have the potential to cause the paradigm  shift in business practices that many experts are predicting? Explain  why or why not.  Support your answer with research. 

(2)  Is there evidence to suggest that Blockchain technology will change the  way HR is practiced? If there is, discuss that evidence. If there is  not, what issues exist that impede its adoption?

(3)  Which functions of human resource management could be most impacted by  Blockchain technology? How might the HR functions change? Support your  answer with research.

Course writing requirements:

• References  MUST be cited within your paper in APA format. Your reference page and  in-text citations must match 100%. Papers without in-text citations will  earn failing grades.
• Always include a cover page and reference page with ALL submissions (even initial discussion posts) 
• Provide  the EXACT web link on the reference page citations for all online  sources – do not provide just the home page, but the EXACT LINK – I  check all sources
• No abbreviations, no contractions – write formally
• Write in the third person formal voice (no first or second person pronouns)
• Write MORE than the minimum requirement of the word count assigned
• As  always, the word count is ONLY for the BODY of the paper – the cover  page, reference page, and / or Appendix (if included) do not count  towards the word count for the paper 
• Indent the first line of each new paragraph five spaces
• Use double-spacing / zero point line spacing, a running header, page numbers, and left justify the margins.

In 80 words or more explain what does the Chief Data Officer have to do with EDMS and data? 

Paste the code into MIPS 

Next, please comment each line of code in the .text section. Please do this FIRST! It will make tracing through the code much easier. 

Once you understand what the code is doing, you’ll notice there is a ‘print_a’ function that is not reachable through the execution path of the code as it’s written. Your job is to devise an input that overflows the call stack and overwrites the $ra register causing the program to execute the ‘print_a’ function. Please provide the successful input that triggers the overflow, a screenshot of the successful execution of your attack that prints the A+ message, and a detailed description of how you figured out how to exploit the buffer overflow and how you devised the proper input.

The major team research project will be turned in during residency weekend.  Each student will be assigned to a group (Executive Team) to complete the project. The research project will focus on research related to a cloud computing topic of your team’s choice.  Pre-work on the project including the proposed Title and Outline should be emailed to the professor early for review and acceptance on Saturday afternoon.  The team should then begin to work on the project Saturday afternoon of the residency to be sure it can be completed during the Residency weekend. 

Requirements for the research paper include… 

• Must be written in APA format and should be 20-25 pages long. 

• Contain at least 3-5 works cited (references)

• At least 2 of the works cited should be peer-reviewed articles ( not more than 5 years old)

• No Wikipedia citations

 Go online and research some tools that would be valuable in collecting both live memory images and images of various forms off media. Put together a shopping list for your manager that includes tools needed  to be purchased. Include a price if applicable. 

Many organizations lack a clear and concise security policy. Without a policy there is often an inconsistency in security focus by employees and management and increased opportunities for experiencing security incidents.

Respond to the following in a minimum of 175 words:

• Search the internet for two companies’ policies.
• Analyze the policies to determine commonalities.
• What would be your top three concepts that should be included in an organizational security policy mission statement? Explain your reasoning for your listed three concepts.
