•Find a company that has suffered a security breach in 2019. Provide background information on the company such as the type of business, their services, public or private, locations, etc. The reader should have a good understanding of the company after reading the bio. Next, provide information on the security breach; the Who, What, When, Where, Why, and How. 

•Create an Incident Response Plan (IRP) for the company. You can use the breach as a foundation if desired. The IRP should be a professionally looking document that is included as an attachment.

•Create a Disaster Recovery Plan (DRP) for the company. Again, you can use the previous breach as a foundation if desired. The DRP should be a professionally looking document that is included as an attachment.

Will blockchain transform capital markets? Yes or no? Explain your reasoning

• Read the Case Study:
   (this case study is attached) 
• Write a summary analysis and what is your opinion of the discussion? What is the high point that convinces you that Corporate governance compliance does make a difference in the operating performance?

1. Calculate the timing of password-guessing attacks:

(a) If passwords are three uppercase alphabetic characters long, how much time would it take to determine a particular password, assuming that testing an individual password requires 5 seconds? How much time if testing requires 0.001 seconds?

(b) Argue for a particular amount of time as the starting point for “secure.” That is, suppose an attacker plans to use a brute-force attack to determine a password. For what value of x (the total amount of time to try as many passwords as necessary) would the attacker find this attack prohibitively long?

(c) If the cutoff between “insecure” and “secure” were x amount of time, how long would a secure password have to be? State and justify your assumptions regarding the character set from which the password is selected and the amount of time required to test a single password.

  2. Describe each of the following four kinds of access control mechanisms in terms of (a) ease of determining authorized access during execution, (b) ease of adding access for a new subject, (c) ease of deleting access by a subject, and (d) ease of creating a new object to which all subjects by default have access.

• per-subject access control list (that is, one list for each subject tells all the objects to which that subject has access)

• per-object access control list (that is, one list for each object tells all the subjects who have access to that object)

• access control matrix

• capability

3. Design a protocol by which two mutually suspicious parties can authenticate each other. Your protocol should be usable the first time these parties try to authenticate each other.

4. List three reasons people might be reluctant to use biometrics for authentication. Can you think of ways to counter those objections?

  5. If you forget your password for a website and you click [Forgot my password], sometimes the company sends you a new password by email but sometimes it sends you your old password by email. Compare these two cases in terms of vulnerability of the website owner.

  6. Defeating authentication follows the method–opportunity–motive paradigm described in Chapter 1. Discuss how these three factors apply to an attack on authentication.

  7. Suggest a source of some very long unpredictable numbers. Your source must be something that both the sender and receiver can readily access but that is not obvious to outsiders and not transmitted directly from sender to receiver.

  8. Humans are said to be the weakest link in any security system. Give an example for each of the following:

(a) a situation in which human failure could lead to a compromise of encrypted data

(b) a situation in which human failure could lead to a compromise of identification and authentication

(c) a situation in which human failure could lead to a compromise of access control.

 9. Explain why hash collisions occur. That is, why must there always be two different plaintexts that have the same hash value? 

10. What property of a hash function means that collisions are not a security problem? That is, why can an attacker not capitalize on collisions and change the underlying plaintext to another form whose value collides with the hash value of the original plaintext?

Select your final project topic. It must be unique. It should be a high level topic related to this course. Pick a topic that you will learn something from or that will be useful in your work. It must be specific not generic. Your final project will consist of a 12 minutes, 12 slide powerpoint presentation that you will present at residency and a 1 page single spaced summary and an annotated reference list as described below all of which will be submitted in Week 15. 

You must also respond to two of your peers’ proposals. Help them make a better, more focused, and more interesting presentation. 

Defend your choice of topic in 500 words or more. Include at least 3 expert supporting quotes surrounded by quotation marks and cited in-line. Provide an annotated reference list at the end. Annotations consist of two paragraphs of at least five sentences each about each of at least five references. The first paragraph should summarize the content of the source and the second are your thoughts or reflections about the source.

DEFINITION: a brief definition of the key term followed by the APA reference for the term; this does not count in the word requirement.

SUMMARY: Summarize the article in your own words- this should be in the 150-200 word range. Be sure to note the article’s author, note their credentials and why we should put any weight behind his/her opinions, research or findings regarding the key term.

ANALYSIS: Using 300-350 words, write a brief analysis, in your own words of how the article relates to the selected chapter Key Term. An analysis is not rehashing what was already stated in the article, but the opportunity for you to add value by sharing your experiences, thoughts and opinions. This is the most important part of the assignment.

REFERENCES: All references must be listed at the bottom of the submission–in APA format and only use journal articles

In chapter 7, the author briefly discusses how to deploy a smart contract. You’re using Ganache in your labs, but you’ll learn in future chapters about public test blockchains and production (live) blockchains. Once you deploy a smart contract, that smart contract code is stored on the blockchain forever (remember immutability?) Understanding that you cannot simply overwrite previously deployed smart contracts, contrast approaches to deploying traditional applications and blockchain apps. Does blockchain make deployments easier or harder? Are there any potential risks when deploying blockchain apps that either don’t exist in traditional environments or aren’t as prominent? What should a development organization do differently to mitigate these risks?

 Please use the attached rubric to guide your writing. Please review the example Literature Review for guidance. 

Requirements:

Times New Roman font, 12 point, double spaced

4-7 pages

10+ sources (Peer-reviewed articles )
