"We have 1.2 billion people and will be largest in terms of population country in the world in years to come. This (cyber crime) affect us perhaps much more than any other country in the world," Telecom and IT Minister Kapil Sibal said on sidelines of 3rd Worldwide Cybersecurity Summit.

The Minister added that priority for India at present is to protect its infrastructure like nuclear, aviation, banking infrastructure, among others.

"I presume multi-dimensional and multi-sectoral infrastructure will be established in different area. In the Department of Electronics and IT (DEITy) itself we must have investment of USD 200 million in next four years to create necessary infrastructure. We are working on that," DEITy Secretary J Satyanarayana said.

Sibal said global community must come together to resolve cyber security issues.

"Global community must realise that these issue cannot be resolved bilaterally. The nature of this space is that there are no boundaries," Sibal said.Citing reports, the Minister said that threats to Cyberspace have increased dramatically in the past years affecting 431 million adult globally or 14 adults victims every second or one million cybercrime victims every day.

"What is more worrisome is that cyber crime has now become a business which exceeds a trillion dollars a year in online fraud, identity theft...affecting millions of people around the world," Sibal said.

The Minister said no nation can fight cybercrime or secure its cyberspace in isolation and called for urgent need to work on agreements on international standards.

The Minister said that there is need to jointly work on devising standardised and coordinated response strategies along with comprehensive cyber security strategy.

"Among this, it very important to build awareness among users for responsive use of cyber space," he said.

The Minister extended India's support to global community in addressing cyber security challenge.

"India pledges to work with the global community in the field of cyber security and we believe that this initiative would be the foundation for economic growth, social progress...tacking cyber crime," Sibal said.
