New Delhi, Dec 24 (ANI): Scientific Adviser to the Defence Minister and DRDO Director General Avinash Chander said that the country has one of the most difficult neighbourhoods in the world. Chander was delivering the 27th Intelligence Bureau Centenary Endowment Lecture 2014 in New Delhi. Addressing a gathering of security experts and Intelligence Bureau (IB) personnel on the subject 'Emerging Technological Challenges for National Security', Chander said security challenges are going beyond traditional domains of land, air and sea as the world is witnessing newer challenges due to the evolution of cyber space, which is both a bane and boon. Before independence, he further said, India was subjugated under foreign rule, whereas 67 years down the road, the country is facing internal and external challenges. Meanwhile, director of IB, Syed Asif Ibrahim, said the scientific and technological capital that we have acquired and accumulated has helped the country immensely in sustaining the overall growth trajectory.
