Jane has an intent to penetrate the network in an organization. She has used passive reconnaissance to gather extensive information on the company. She finds out the model numbers of routers and other devices by reading discussions between system administrators in forums. She also has a list of all the IT staff and their phone numbers. She also has the services running on ports on some machines she ran a network scanner on. Required:
a. What reasonable steps should the company have taken to prevent Jane from finding this information?
b. What steps should the company take to prevent or reduce the efficacy of port scans?

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
