The risk of data leak and hacking by cyber criminals is increasing as smartphones become more and more complex and internet penetration widens. India saw 53,000 incidents of cyber attacks last year, most of them allegedly coming from China, according to data released by the government. "Cyber security is one area where the threats are asymmetric; there can be rogue elements anywhere. There could be fancy products that may mean trouble to the nation. So we need to develop products that are one step ahead of adversaries," G Satheesh Reddy, chairman, Defence Research and Development Organisation, told NDTV.
