Question
Chapter 8, Problem 3RQ
Program Plan Intro
System vulnerability:
- When huge data amounts are been kept in electronic form, it becomes susceptible to many threats.
- The information systems in many locations are been interconnected through communication networks.
- The unauthorized access can occur at many access points in network and is not limited to single location.
- The data flowing over networks could be accessed; valuable information could be stolen while transmission or data could be altered without authorization.
- The denial-of-service attacks are launched by intruders to disrupt website operations.
- Internets are vulnerable than internal networks as it is open to everyone.
Explanation of Solution
Application Controls:
- Application controls denote specific controls that are exclusive to each application.
- It includes both manual as well as automated procedures.
- It ensures that authorized data is been processed by application.
- The types include:
-
o Input controls:
- It checks data for correctness as well as completeness while they go in system...

o Input controls:
Explanation of Solution
Risk assessment function:
- A risk assessment would determine risk level to firm if an explicit activity is not controlled properly.
- The information assets value, vulnerability point, likely problem frequency and damage potential can be determined by business managers.
- Controls could be added or adjusted to focus on greater risk areas.
- Security risk analysis would involve determination of what is needed to be protected and the manner to protect.
- It denotes an examining process for risks of firm and ranking for those risks by severity level.
- The cost effective decisions are been involved in process...
Explanation of Solution
Security policy, Acceptable use policy and Identity management:
- A security policy denotes ranking of information risks, identification of acceptable goals of security as well as identification of
mechanism to achieve goals.- o It drives policies that determine acceptable information resource usage of firm.
- o It determines access details of company’s information assets.
- An acceptable use policy denotes acceptable uses of resources of firm and equipment for computing.
- o It includes desktop, laptop, wireless devices, Internet and telephones.
- o It clarifies privacy, responsibility of user as well as personal usage for company equipment policies...
Explanation of Solution
Information systems auditing promotes control and security:
Information system auditing determines effectiveness of information system security as well as control.- An MIS audit would identify all control...

Change the following code so that there is always at least one way to get from the left corner to the top right, but the labyrinth is still randomized.
The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. Take care that the player and the dragon cannot start off on walls. Also the dragon starts off from a randomly chosen position
public class Labyrinth { private final int size; private final Cell[][] grid;

Change the following code so that it checks the following 3 conditions:
1. there is no space between each cells (imgs)
2. even if it is resized, the components wouldn't disappear
3. The GameGUI JPanel takes all the JFrame space, so that there shouldn't be extra space appearing in the frame other than the game.
Main():
Labyrinth labyrinth = new Labyrinth(10);
Player player = new Player(9, 0); Dragon dragon = new Dragon(9, 9);
JFrame frame = new JFrame("Labyrinth Game"); GameGUI gui = new GameGUI(labyrinth, player, dragon);
frame.add(gui); frame.setSize(600, 600); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true);

The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

- In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…arrow_forwardHow do you distinguish between hardware and a software problem?
