How could a corporate user with an unauthorized Wireless USB CDMA adapter from Verizon create a backdoor into the network? CDMA broadcasts in plaintext. Since it is easy to do, an attacker is likely to hack the CDMA signal and intercept wireless packets. This would not create a backdoor since they are two separate networks. This would inadvertently create a network bridge that could allow access to content behind the business's security controls.

Part d: float check string has a method s.isdigit() that returns true if string s contains only digits and false otherwise, i.e. s is a string that represents an integer. write a function named float_check that takes one parameter that is a string and returns true if the string represents a float and false otherwise. for the purpose of this function we define a float to be a string of digits that has at most one decimal point. note that under this definition an integer argument will return true. remember “edge cases” such as “45.” or “.45”; both should return true. for example: float_check('1234') returns true float_check('123.45') returns true float_check('123.45.67') returns false float_check('34e46') returns false float_check('.45') returns true float_check('45.') returns true float_check('45..') returns false
