Discussion 1/Discussion Question: If passwords are three characters of either uppercase or lower case alphabetic characters, how much time would it take to determine a particular password, assuming that testing an individual password requires 5 seconds? If the cutoff between insecure and secure were x amount of time, how long would a secure password have to be? State and justify your assumptions regarding the character set from which the password is selected and the amount of time required to test a single password. Does your answer change, if a computer can test 1,000 passwords per second? Explain what this tells you about passwords and why 2 factor authentication (or more) matters.
