a.If passwords are three uppercase alphabetic characters long, how how much time would it take to determine a particular password, assuming that testing an individual password requires 5 seconds?

Argue for a particular amount of time as the starting point for "secure." That is, suppose an attacker plans to use a brute force attack to determine a password. For what value of x (the total amount of time to try as many passwords as necessary) would the attacker find this attack prohibitively long?

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.
