network security and system
At one millisecond per guess, it takes an attacker about 3.4 hours to try all possible upper-case only passwords of length


In case you have any doubts or you did not understand any step please feel free to ask your doubts in comments section. I would be happy to clarify it
DO GIVE A THUMBS UP!!

2. Trying the correctness of a password takes 1 millisecond in brute force attack. Assume that the user decides to use 6-character long password. For each of the following cases, find the total amount of time to try all possible passwords. (a) Lower-case letters are used (b) Lower or upper-case letters are used (c) Lower or upper-case letters or digits are used
PYTHON 1.Guessing many passwords: Write a function called guess_passwords. It doesn't take any arguments. It should use the function guess, trying out as many possible passwords as possible. Here are some methods you might try: Try out a hardcoded list of strings that you think people might use as passwords. Try out all words in the word file. Try out all character combinations of length 4 or less (or more if you don't mind waiting). Try out combinations of words...
Suppose that you open an email account and you are told that you need six-character password & the characters must be alpha-numeric ( either alphabetical or numerical). Assume that a lower case letter is different from an upper case one. a) How many passwords are possible? Give the exact answer and do not use scientific notation. Show some work. b) Suppose a computer hacker tries to guess what your password is by testing all possible passwords and it takes his...
please write about your computer network/internet access security system. Write a one to two page reflection on your experience in this week's lab. Were you surprised by any of the results? In what way? How do you feel about your information passing through a number of devices on the way to its destination? Would you feel differently if you knew some of those devices were not properly secured?
Alice wants to evaluate a picture-based password system. The system has a database of 100 different pictures. To select a password, the user is allowed to browse through the database of pictures and select 20 pictures as their password. To authenticate, the user is presented with 20 challenges. Each challenge consists of 2 pictures displayed to the user: one is randomly chosen from the user's password set, and the other is randomly chosen from the remaining 80 pictures. The user...

Part 1: Is this Crazy Password Valid? A good password (in this strange system) should have the following properties: Rule 1: The password should be between 4 and 25 characters inclusive, starting with a letter. Rule 2. The password should not be contained in a list (selected by the user) that contains passwords commonly used by many people thus making these passwords easy to guess. Comparisons with passwords from the list of common passwords should be case insensitive. For example,...
The opening case, ‘Hackers Attack the SWIFT Global Banking Network’, discusses breaches in the system of several banks that are a part of the SWIFT network. The case is an example of the importance of information system controls. Explain some of the security risks associated with information systems as well as some security and control measures that can be implemented to protect against these security risks. Hackers Attack the SWIFT Global Banking Network SWIFT, which stands for Society for Worldwide...
This project is to be performed individually or by a group of up to two students. You willl use C++ and /or Assembly programming language to develop the project described below. You will turn in a printout of the source code and a report as assigned. No late work will be accepted! Think about the following scenario: SYSTEM: An ATM requires a four digit pin-number (0 to 9999). ATTACK: A hacker is trying to find a PIN number to access...
