Program Set 2 10 points) Credit card number validation Program Credit card numbers follow certain patterns: It must have between 13 and 16 digits, and the number must start with: 4 for Visa cards 5 for MasterCard credit cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card...

Validating Credit Card Numbers Write a program named Creditcard.java that prompts the user for a credit card number and determines whether it is valid or not. (Much of this assignment is taken from exercise 6.31 in the book) Credit card numbers follow certain patterns. A credit card number must have between 13 and 16 digits, and must start with: 4 for Visa cards 5 for Master cards 6 for Discover cards 37 for American Express cards The algorithm for determining...

Credit card numbers follow certain patterns. A credit card number must have between 13 and 16 digits. The number must start with the following: 4 for Visa cards 5 for MasterCard cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or is scanned correctly by a scanner. Almost all credit card numbers...

Computer Guesses - Create a page that allows the user to think
of a number from 1 to 100. Write a function that will guess the
number the user chose. The user will provide clues: higher or lower
and correct. It should take no more than 7 guesses to get the
correct number.
User Guesses - Create a page that generates a random number from
1 to 100. Allow the user only 7 guesses to guess the number.

Discuss the particulars of each attack scenario and how Kerberos defends against it. 1. A user gains access to a particular workstation and pretends to be another user from that workstation. 2. An attacker acts as the “man in the middle” between two computers (e.g. client and the server). The attacker spoofs each computer to “think” they have connected to the correct computer, when in fact the attacker is intercepting all transmissions. The attacker can then monitor or change any...

Write a Java Program that reads the following:
Ask the user for a balance. From the
accounts.dat file, display all the accounts that
have a balance of at least what the user entered.
accounts.dat is a binary file. Each entry
contains a credit card number (long), a balance (double), and a
cash back flag (boolean).

Write a C program that asks the user to think of an integer number from 1 to 20. Have the computer guess what the number is by using a binary tree to determine the next guess. You can create the binary tree “by hand” by typing in a set of malloc commands and explicitly linking the nodes. (make the tree completely, then traverse the tree) Use a menu to provide the user with a selection to answer the results of...

1. A computer security risk is any event or action that could cause a loss of or damage to computer hardware, software, data, information, or processing capability 2. A cybercrime is an online or Internet-based illegal act 3. Information transmitted over networks has a higher degree of security risk than information kept on an organization's premises 4. Users can take several precautions to protect their home and work computers and mobile devices from these malicious...

(1 point) Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace the card, and draw another card. You repeat this process until you have drawn 15 cards in all. What is the probability of drawing at least 5 diamonds? For the experiment above, let X denote the number of diamonds that are drawn. For this random variable, find its expected value and standard deviation E(X)=( o=
