The company is trying to decide between increasing the minimum password length of users, or requiring them to use extra symbols for their passwords. a) Use fundamental counting principle to determine the number of possible passwords for each of the provided scenarios (A, B, C and D) D) Then, determine how many times scenario

) or

) is more secure than the other. and how many times scenario C ) or D ) is more secure than the other. The best way to do this is to divide the greater number of arrangements by the smaller number of arrangements in each pair. wi) After this, analyze your results and create a short argument (roughly

sentences) on whether the company should increase the minimum password length, or require extra symbols in the passwords. You must justify the reasoring of your argument using your calculations. A) Require users to use extra symbols, increasing the number of choices per character by 11 . B) Require users to increase the minimum password length from 5 characters long to 6 characters long. C) Require users to use extra symbols, increasing the number of choices per character by 16. D) Require users to increase the minimum password length from 5 characters long to 7 characters long.
