When going to China or Russia or other few countries that don’t allow encrypted devices to enter their borders without government approval, its hard-to-believe the precautions that employees of corporations with sensitive information take while travelling.
In a report given by ‘The New York Times’, there is a detailed information of precautions given by Brookings Instituion’s Kenneth G. Lieberthal. He has a seperate set of in-China and at-home devices. Some of the various precautions he takes includes removing the battery from his phone during meetings to avoid being recorded, he also keeps Bluetooth and Wi-Fi off at all times, and only copies and pastes his passwords from a flash drive in order to prevent keyloggers. Similar precautions are often used by amplyees at McAfee, Google, and various US government agencies.
