Chapter 2, Problem 2.19.1E
Explanation of Solution
The value of $t2:
The given is:
$t0 = 0xAAAAAAAA
$t1 = 0x12345678
Let consider the given question as:
sll $t2, $t0, 4
or $t2, $t2, $t1
- The “sll” instruction is used to shift one position left to the bit. Here the register value “$t0” is shifted 4 positions left to the bit and finally store the result in the “$t2”.
- The “or” instruction is used to “OR” the constant value to the register “$t2” and store the result in the “$t2”.
Step1: Convert the hexadecimal value into the binary value.
The corresponding binary value of “A” = 1010
The corresponding binary value of “1” = 0001
The corresponding binary value of “2” = 0010
The corresponding binary value of “3” = 0110
The corresponding binary value of “4” = 0100
The corresponding binary value of “5” = 0101
The corresponding binary value of “6” = 0110
The corresponding binary value of “7” = 0111
The corresponding binary value of “8” = 1000
Step2: Left shift the “$t0” value
Here the first four bits removed and “0s” are added in the last 4 position

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 in the Login - Apply a SQL injection (Search / GET) to list the database tables
- 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)?
- Include screenshots of the entire procedure and the answers to each question
