Expert Solution & Answer
Chapter 13, Problem 13.7E
Explanation of Solution
Attacks on equity trading system:
In the equity trading systems, user accounts and equity prices are replicated across servers so that orders can be placed making use of user account
Some of the attacks that can happen to equity trading system and the stratergies to counter them are:
- Attack in which a malicious user gains access to the system using accredited user credentials and then malicious orders are placed and stock is bought and sold.
The strategy to counter attack is mentioned below:
- Resistance: In order to place an order a dealing password is required which must be different from login password.
- Recognition: One can send a copy of order by email to authorized user with contact phone number and maintain user’s order history and unusual trading patterns...

A Personal Address Book application program allows the user to add, delete, search, save, and
load contact information. The program separates the user interface (command-line) and the
internal processing subsystem. The internal processing system consists of the following classes:
•
•
Contact Manager (responsible for add and delete operations)
Contact Finder (responsible for the search operation)
pataManager (responsible for save and load operations)
a. What design pattern can be used to implement the user interface? Explain your answer using a
class diagram for the entire system.
b. Draw a UML sequence diagram to show the behavioral view of the Personal Address Book
program, demonstrating what happens when a user enters new contact information.
A system comprises three components: A, B, and C. Calling A requires calling B, and calling B
requires calling A. Component C is responsible for dissimilar tasks T#1, #2, and T#3.
a. Comment on the modifiability of this system. What problems do you see in this system, and
how would you solve them?
b. Suppose that T#1 is performed by both component A and C. What does this indicate about A
and C? How would you solve this problem?

- Implement a C program to find the largest element in a given array. You must have a main function and a max function. The function int main() will declare an array with the values {12, 100, 10, 1000, 20, 5}. This array will be passed to the max function. The function int max() will perform the necessary operations to find the largest element of the array. After max () is finished, have main () print the largest value and its index in the array. Do not hard code your solution! If we test your code with different array values, we should still get the correct output.
