What Happened
The Defense Department has tightened cybersecurity requirements for tech companies that sell cloud computing services to the Pentagon.
The updates, issued this month, ban IT vendors from using China-based personnel to work on department computer systems and require companies to maintain a digital paper trail of maintenance performed by their foreign engineers.
Background
The changes follow a ProPublica investigation that exposed how Microsoft used China-based engineers to maintain government computer systems for nearly a decade — a practice that left some of the country’s most sensitive data vulnerable to hacking from its leading cyber adversary.
