Under NO circumstances will late submissions be accepted! You must work individually. Good luck! Student Full Name: __________________________________ Student ID: ______________________ 1. [1 point] What is an information security policy and how is it applied to an organization’s information technology enterprise? 2. [1 points] What are some key trends and changes in cyber crime since the early 2000s? Give detailed examples. 3. [1 point] What are some primary characteristics between risk assessment and risk management that managers need to consider? 4. [1 point] Discuss some implications on network security by having multiple layers of protocols that must openly communicate with each other. 5. [1 point] What are some of the differences between DoS and DDoS? 6. [2 points] Describe some of the differences between network architecture and network implementation, and give some examples of their relationships or how they “function†together. 7. [1 point] Discuss what the concept of tunneling involves in relation to VPNs. 8. [1 point] Explain how PGP encryption works, and explain why it is considered a hybrid public/private key cryptography. 9. [2 points] What countermeasures would be important to control access to a server room? Discuss these in terms of cost, schedule and performance (e.g., importance, benefits, etc.). 10. Online Banking Case Study: Answer the following questions based on the information provided below. Information security risk assessment is the process used to identify and understand risks to the confidentiality, integrity, and availability of information and information systems. In its simplest form, a risk assessment consists of the identification and valuation of assets and an analysis of those assets in relation to potential threats and vulnerabilities, resulting in a ranking of risks to mitigate. The resulting information should be used to develop strategies to mitigate those risks. Risk assessments for most industries focus only on the risk to the business entity. Financial institutions must also consider the risk to their customers' information. For example, U.S. federal regulations require financial institutions to "protect against unauthorized access to or use of customer information that could result in substantial harm or inconvenience to any customer." ACME Financial Corporation is planning to roll out their new web and mobile online banking application. However, before deployment, the CEO has asked you (CISO) to assess risks and vulnerabilities, and provide strategies to protect customer data. For this analysis, you will utilize the following formula: Risk-Rating Factor = (Asset Impact x Likelihood) – Current Controls + Uncertainty You may assume that ‘Likelihood’ is a numerical value within the scale (0.1 – 1.0) and ‘Asset Impact’ is a numerical value within the scale (1 – 100). ‘Current Controls’ is a numerical value based on the percentage of risk mitigation from control mechanisms. ‘Uncertainty’ is a numerical value based on the current knowledge of the vulnerability. You shall determine all values based on your knowledge, experience and/or references for each of the five assets and vulnerabilities. Be sure to explain how you derived all values. 10a. [2 points] Describe how the information security group should be organized. Illustrate using a hierarchical organization tree. Also, list any policies that should be considered and by whom. 10b. [4 points] Identify and prioritize 5 assets by calculating risk determination based on vulnerability likelihood of occurrence, percentage of risk mitigated by controls, and uncertainty of knowledge. Complete Table 1 below with your data. Explain how you derived each data set. Example: Asset 1 has an impact of 100 and has one vulnerability where the likelihood is 0.1 with a current control that addresses 50% of its risk and current knowledge (assumptions and data) is at 80% accuracy.

[3 points] Based on the organizational structure, policies and risk assessment, what strategies will you implement to mitigate your risks. What other considerations will impact your decisions? You may also illustrate protection mechanisms in a system boundary diagram. CIS 5600 Final Exam Page 1 Write a 4- to 5-page report (excluding cover page and references) answering the following questions. 1. What are the functions of data link? 2. Why and where is flow control needed? Explain its parameters. 3. Explain stop-and-wait flow control with special reference to the handling of (i) a damaged frame (ii) a lost frame. 4. Explain HDLC. What are the categories of HDLC stations? 5. What is the configuration and modes of HDLC? 6. What does "switching" mean? Explain the three possible switching methods.
