Review the following questions from Network security: Private communication in a public world and provide your responses in a Word document. In answering each prompt, be sure to defend your answers and explain how you have arrived at your solution.

1. Random J. Protocol-Designer has been told to design a scheme to prevent messages from being modified by an intruder. Random J. decides to append to each message a hash of that message. Why does this not solve the problem?

Hint: We know of a protocol that uses this technique in an attempt to gain security.

1. Suppose Alice, Bob, and Carol want to use secret key technology to authenticate each other. If they all used the same secret key, K, then Bob could impersonate Carol to Alice (actually any of the three could impersonate the other to the third). Suppose instead that each had their own secret key; so Alice uses KA, Bob uses KB, and Carol uses KC. This means that each one, to prove his or her identity, responds to a challenge with a function of his or her secret key. Is this more secure than having them all use the same secret key?

Hint: What does Alice need to know in order to verify Carol’s answer to Alice’s challenge?

1. Assume a cryptographic algorithm in which the performance for the good guys (the ones that know the key) grows linearly with the length of the key and for which the only way to break it is a brute-force attack of trying all possible keys. Then, suppose the performance for the good guys is adequate (e.g., it can encrypt and decrypt as fast as the bits can be transmitted over the wire) at a certain size key. Finally, suppose advances in computer technology make computers twice as fast. Given that both parties— the good guys and the bad guys— get faster computers, does this advancement in computer speeds work to the advantage of the good guys? The bad guys? Or does it not make any difference?

Kaufman, C., Perlman, R., & Speciner, M. (2011). Network security: Private communication in a public world. Upper Saddle River, NJ: Prentice Hall PTR. (note: this textbook is a reference for the assignment and not a required resource for learners)

In each of your responses to the above scenarios, please ensure that you provide a brief explanation of why you chose to take your mentioned actions.

The purpose of this hands-on project is to give students an opportunity to create a hierarchical folder structure (CLO 1, MLO 1.1) and explain key terms and concepts related to information systems (CLO 7, MLO 1.3). To do this, use the weekly readings, along with the video tutorial, to complete the Essential Concepts Project.

Part 1. Read the following modules in the Technology for Success textbook:

• Module 3: Computer Hardware (pages CC 3-1 to CC 3-28)
• Module 4: Operating Systems and File Management (pages CC 4-1 to CC 4-21)
• Module 5: Software and Apps (pages CC 5-1 to CC 5-33)

Next, create a new Microsoft Word document (.docx). In 2-3 pages, answer the following questions:

1. What does it mean to live in a “modern information society?”
2. What types of input and output devices would be ideal for a college student completing his or her coursework?
3. What characteristics are common among operating systems? List types of operating systems, and examples of each. How does the device affect the functionality of an operating system?
4. Leah Jacobs is starting her own dance studio and wants to create digital media and use productivity software to support her business. She is hiring a graphic artist to create a logo for her business. She wants to use the logo across all visual communications at the company, from business cards to database forms, to websites and social media. What programs and apps should she consider using to run her business?

Part 2. Create a class folder so that you can save files in the proper folders. As an organization scheme, do the following:

1. Create the folders you need onto the location of your choice. This may be your Documents folder, a flash drive, or the desktop if you are working on a CBU machine. Begin by creating a folder called LastnameFirstname. Inside of the LastnameFirstname folder, create a folder called CIS 265. Inside the CIS 265 folder, create the following folders: Office and Operating System, Word, PowerPoint, Excel, Access, and Outlook, Integrated Capstone Project.

2. Expand the hierarchical tree so that all the folders are visible (via Windows Explorer).

3. Press the Prnt Scrn button on your keyboard. This will take a snapshot of the screen and put it in the computer’s clipboard (temporary memory).

4. Open the document you’ve already created for this Essential Concepts assignment. Press the Paste button or press Ctrl and V. This should paste a picture of the screen onto the last page of the document.
5. The finished product should consist of a copy of the screenshot showing that you have created the folders.


(IMPORTANT: You should use these folders to save all your work throughout this course.)

Part 3. Attach and submit your completed project (which should be a single Word document with word processing and/or screen shots (in Full Screen Reading view) of all assignment components, labeled and in order) by the assigned due date.
