Case Study 3: Security A large fast-food chain unveiled a new touch screen register for its franchises. Each cashier was assigned a user id and password combination to log in to the register. The system allowed the incorrect password to be entered four (4) times before the register would lock and require a manager to unlock it with a key card. To prevent unauthorized access the registers would lock after three (3) minutes if the screen was not touched. When the register locked only the cashier who was logged in prior to it locking could unlock it without a system restart.
