Question 1
a) Distinguish between an IP address and a port address. Your answer should describe the general packet structure (with diagram), which layers of the TCP/IP-OSI relate to IP address and port address, and how the IP address and port address ensure correct delivery of the packet.
They are both necessary for correctly routing traffic to its destination but have different scope. An IP address identifies a particular computer on the Internet. The port number identifies a particular program running on that computer.
b) List the five ‘quality of service’ parameters that we have discussed this semester and that form a central platform in information security management. Concisely explain the meaning of each of these parameters. Please give an everyday example of each parameter in business life.
1. Tangibles: Appearance of physical facilities, equipment, personnel, and communication materials. Example: have a clean office.
2. Reliability: Ability to perform the promised service dependably and accurately. Example: provide qualify services to customers.
3. Responsiveness: Willingness to help customers and provide prompt service. Example: fast E-mail response.
4. Assurance: Knowledge and courtesy of employees and their ability to convey trust and confidence. Example: train for qualify staffs
5. Empathy: Caring, individualized attention the firm provides its customers. Example: service with smile.
c) A work colleague says to you: “We do business via Web processing of payment card (i.e. debit and credit cards) information. We need to collect all payment card details for each transaction over a secured Web connection.” Which of the five quality of service parameters (ref: question (b)) are involved in logically securing this Web connection for each and every transaction? Explain your answer.
1. Reliability, the business process payment card which contain important information from customers. Thus, the reliability of business system may be showed
