Get Permission The Department of Homeland Security is warning U.S. companies about data theft risks associated with the use of Chinese technology and digital services. In an advisory, DHS says that American businesses that rely on Chinese tech will be prone to government-sanctioned data theft under a new law in China that enables the government to require firms to turn over data “under the pretense of national security.” U.S. businesses using Chinese technology - or services that are connected remotely to Chinese companies - should minimize the amount of data stored in China because it may be accessible by government authorities, DHS advises.
