Textbook Question
Chapter 6, Problem R1RQ
Consider the transportation analogy in Section 6.1.1. If the passenger is analagous to a datagram, what is analogous to the link layer frame?
Expert Solution & Answer
Program Plan Intro
Link Layer:
- In the OSI (Open Systems Interconnection) model, data link layer is the 2nd layer. This layer is used to transfer data between neighboring network nodes on a Wide Area Network or on the same Local Area Network.
- This layer uses error detection bits and it corrects the errors.
Explanation of Solution
Transportation analogy:
In the section 6.1.1, the travel agent plans a trip for tourists from different places.
- The travel agent decides the convenient plans for the tourists and the agent makes three reservations.
- The three reservation trips are direct between two adjacent locations and also they contain different transportation modes.
- Here, if the passengers are analogous to the datagram, then the transportation modes are analogous to the link layer frame.
Therefore, the transportation modes are analogous to link layer frame.

Question 6:
A major Saudi book retailer is planning to develop a computer system to handle the store’s new online bookshop: BookShop.com. You have been chosen to do the analysis and design. As part of the development of the system, perform the following tasks:
1.Write Expanded Use Cases for buying a book from the shop using a credit card.
2.Draw an Expanded Use Case for the following interactions:
•Buying a book from the shop using a credit card.
•Checking the status of one’s orders (being filled, shipped, etc.)
•Pay for Product
•Validate customer identity
Use Case: Buy Book
Actors: Customer
Purpose: To buy a book from BookShop.com using a credit card.
Overview: A customer has selected a book to buy at the Murray.com website. The system prompts for the customer’s username and password. The customer enters these details. The system verifies the customer’s identity and retrieves the customer’s name and address, then prompts for…

- Apply a SQL injection (Search / GET) to list the users and passwords of the DB
Questions:
1.- What was the vulnerability used for the attack? What service was affected?
2.- What type(s) of attack(s) were made?
3.-What was the damage caused to the information asset(s)?
