New Delhi:A majority of the world's top airlines plan to invest in cyber security programmes, travel technology provider SITA said on Monday. According to a survey of the world's top 200 airlines conducted by SITA, a majority (91 per cent) said that they plan to invest in cyber security programmes over the next three years. The survey "SITA Airline IT Trends 2016" revealed that three years ago, less than half of airlines (47 per cent) had said that they were making advanced preparations to manage cyber risks. "The focus on cyber security also reflects the move to the 'Internet of Things' (IoT) in which a vast number of physical objects will become connected to the internet," the travel technology major said in a statement. "This enables tracking, data collection, analysis and control, which necessitates more security. An overwhelming majority of airlines (68 per cent) are investing in IoT programs in the next three years," it added.
